Description:

This class provides an interface for calling functions that are exported from the 3ds Max executable. All the methods in this class are implemented by 3ds Max itself.

Methods are provided for putting up many standard 3ds Max dialogs, working with command modes, working with viewports, controlling the prompt, toolbar and status areas, and working with selection sets. There are also methods for creating objects and nodes in the scene, setting and getting the current time and animation ranges, working with the standard directories of MAX, and many more. See the Method Groups listed below for a breakdown of the various kinds of methods available. Note: When editing in the command panel, a developer gets passed an interface pointer during BeginEditParams(). This pointer is only valid before EndEditParams() is finished. A developer should not hang on to this pointer and call methods on it after EndEditParams() has returned.

Member Function Documentation

GetAppHFont()

virtual HFONT GetAppHFont ( )

pure virtual

Remarks

Returns the handle of the font used by MAX. The default font is the same one returned from GetAppHFont(). So if a developer makes a dialog in the rollup page the correct font will be used automatically.

RedrawViews()

virtual void RedrawViews ( TimeValue  t, DWORD  vpFlags = REDRAW_NORMAL, ReferenceTarget *  change = NULL  )

pure virtual

Remarks

This method may be called to cause the viewports to be redrawn.

Parameters:

TimeValue t

The time at which to redraw the viewports.

DWORD vpFlags=REDRAW_NORMAL

You may specify one of the following:

REDRAW_BEGIN

Call this before you redraw.

REDRAW_INTERACTIVE

This allows the view quality to degrade to maintain interactively.

REDRAW_END

If during interactive redraw the state degraded, this will redraw the views in the undegraded state.

REDRAW_NORMAL

This redraws the views in the undegraded state.

ReferenceTarget *change=NULL

This parameter is not used - always let it default to NULL.

Example:

ip->RedrawViews(ip->GetTime(),REDRAW_BEGIN);

// More code ...

ip->RedrawViews(ip->GetTime(),REDRAW_INTERACTIVE);

// More code ...

ip->RedrawViews(ip->GetTime(),REDRAW_END);

SetActiveViewport()

virtual BOOL SetActiveViewport ( HWND  hwnd )

pure virtual

Remarks

This allows you to specify the active viewport.

Parameters:

HWND hwnd

The handle of the window to activate.

Returns

TRUE if the viewport was not previously active; otherwise FALSE.

GetActiveViewExp()

virtual ViewExp& GetActiveViewExp ( )

pure virtual

Remarks

Returns the ViewExp reference of the active MAX viewport. NOTE: if none of the viewports are active, the first viewport of the current view tab is returned

ForceCompleteRedraw()

virtual void ForceCompleteRedraw ( BOOL  doDisabled = TRUE )

pure virtual

Remarks

Calling this method will cause all the viewports to be completely redrawn. Note: This method literally forces everything (every object, every screen rectangle, every view) to be marked invalid and then the whole scene is regenerated. (The individual object pipeline caches are not flushed, however.) So this routine is guaranteed to be slow.

Parameters:

BOOL doDisabled=TRUE

If TRUE disabled viewports are redrawn; otherwise they are not.

GetIObjCreate()

virtual IObjCreate* GetIObjCreate ( )

pure virtual

Remarks

Returns this interface pointer cast as a IObjCreate pointer.

GetIObjParam()

virtual IObjParam* GetIObjParam ( )

pure virtual

Remarks

Returns this interface pointer cast as a IObjParam pointer.

GetMAXHWnd()

virtual HWND GetMAXHWnd ( ) const

pure virtual

Remarks

Returns the window handle of 3ds Max.

GetQmaxMainWindow()

virtual MaxSDK::QmaxMainWindow* GetQmaxMainWindow ( ) const

pure virtual

Returns the Qt docking main window of 3ds Max.

Use this window to attach your toolbar or dock widget to the 3ds Max main UI. When you create new Qt toolbars or dock widgets, you must use the extended 3ds Max version QmaxToolBar and QmaxDockWidget instead of the Qt standard components.

See also

class QmaxToolBar, class QmaxDockWidget

DisplayActiveCameraViewWithMultiPassEffect()

virtual BOOL DisplayActiveCameraViewWithMultiPassEffect ( )

pure virtual

Remarks

This method will draw the active view (if it is a camera view with a multi-pass effect enabled) with that effect active.

Returns

TRUE if the active view is a camera view with a multi-pass effect enabled, FALSE otherwise.

SetActiveViewportTransparencyDisplay()

virtual BOOL SetActiveViewportTransparencyDisplay ( int  transType )

pure virtual

DisableSceneRedraw()

virtual void DisableSceneRedraw ( )

pure virtual

Turns off scene redraws.

In order to increase the speed of certain operations, scene redraw should be turned off temporarily, then once the operation completed, should be turned back on. Scene redraw should be disabled in implementations of the Renderer::Open() method and re-enabled in implementations of Renderer::Close() method.

Note

Calls to DisableSceneRedraw() and EnableSceneRedraw() should be paired up since the system counts the requests for disabling the scene redraw. If several scene disable requests are issued, it takes an equal number of scene enable requests to re-enable the redrawing of the scene.

See also

EnableSceneRedraw, IsSceneRedrawDisabled, class SuspendSceneRedrawGuard

EnableSceneRedraw()

virtual void EnableSceneRedraw ( )

pure virtual

Turns on scene redraws.

In order to increase the speed of certain operations, scene redraw should be turned off temporarily, then once the operation completed, should be turned back on. Scene redraw should be disabled in implementations of the Renderer::Open() method and re-enabled in implementations of Renderer::Close() method.

Note

Calls to DisableSceneRedraw() and EnableSceneRedraw() should be paired up since the system counts the requests for disabling the scene redraw. If several scene disable requests are issued, it takes an equal number of scene enable requests to re-enable the redrawing of the scene.

See also

DisableSceneRedraw, IsSceneRedrawDisabled, class SuspendSceneRedrawGuard

IsSceneRedrawDisabled()

virtual int IsSceneRedrawDisabled ( )

pure virtual

Tells whether the scene redraw is disabled.

Call this method to find out whether the scene redraw is disabled.

Returns

The count of scene redraw disable requests. This will be positive, if the scene redraw is turned off, and zero or negative if it is turned on.

See also

EnableSceneRedraw, DisableSceneredraw, class SuspendSceneRedrawGuard

RegisterRedrawViewsCallback()

virtual void RegisterRedrawViewsCallback ( RedrawViewsCallback *  cb )

pure virtual

Remarks

Registers a call back object that gets called every time the viewports are redrawn. The proc() method is called after the views are finished redrawing.

Parameters:

RedrawViewsCallback *cb

Points to the callback object whose proc() method is called when the viewports are redrawn. See Class RedrawViewsCallback.

UnRegisterRedrawViewsCallback()

virtual void UnRegisterRedrawViewsCallback ( RedrawViewsCallback *  cb )

pure virtual

Remarks

Un-registers the viewport redraw callback.

Parameters:

RedrawViewsCallback *cb

Points to the callback object to un-register. See Class RedrawViewsCallback.

RegisterSelectFilterCallback()

virtual void RegisterSelectFilterCallback ( SelectFilterCallback *  cb )

pure virtual

Remarks

Registers a call back object that gets called to filter the selection of nodes.

Parameters:

SelectFilterCallback *cb

Points to the callback object to register. See Class SelectFilterCallback.

UnRegisterSelectFilterCallback()

virtual void UnRegisterSelectFilterCallback ( SelectFilterCallback *  cb )

pure virtual

Remarks

Un-registers the select filter callback.

Parameters:

SelectFilterCallback *cb

Points to the callback object to un-register. See Class SelectFilterCallback.

RegisterDisplayFilterCallback()

virtual void RegisterDisplayFilterCallback ( DisplayFilterCallback *  cb )

pure virtual

Remarks

Registers a call back object that gets called to filter the display of nodes.

Parameters:

DisplayFilterCallback *cb

Points to the callback object to register. See Class DisplayFilterCallback.

UnRegisterDisplayFilterCallback()

virtual void UnRegisterDisplayFilterCallback ( DisplayFilterCallback *  cb )

SetSelectionType()

virtual BOOL SetSelectionType ( BOOL  autoWinCross, int  winCrossOrAutoDir  )

pure virtual

MakeExtendedViewportActive()

virtual void MakeExtendedViewportActive ( HWND  hWnd )

pure virtual

Remarks

This method is used with Extended Viewports (see Class ViewWindow). It is called when the extended viewport needs to become active. It should be called whenever the user clicks in the non-3D window (so as to deactivate the current 3D window, and redirect commands like the Min/Max toggle to the non-3D viewport window).

Parameters:

HWND hWnd

The handle of the window which to made active.

PutUpViewMenu()

virtual void PutUpViewMenu ( HWND  hWnd, POINT  pt  )

pure virtual

Remarks

This method is used with Extended Viewports (see Class ViewWindow). It is called to put up the view type popup menu (for example the right-click menu). It should be called when the user right-clicks in a dead region of the non-3D window. This brings up the view selection menu so that the user can choose to replace the current window with a 3D or other non-3D window without having to go to the Views | Viewport Config dialog directly.

Parameters:

HWND hWnd

The handle of the window the menu is to appear in.

POINT pt

The point at which the menu is put up.

Sample Code:

case WM_RBUTTONDOWN:
    pt.x = GET_X_LPARAM(lParam);
    pt.y = GET_Y_LPARAM(lParam);
    GetCOREInterface()->PutUpViewMenu(h, pt);

TrackViewPickDlg()

virtual BOOL TrackViewPickDlg ( HWND  hParent, TrackViewPick *  res, TrackViewFilter *  filter = NULL, DWORD  pickTrackFlags = 0  )

pure virtual

Remarks

This method brings up the track view pick dialog.

Parameters:

HWND hParent

The handle of the parent window.

TrackViewPick *res

The item chosen by the user. See Class TrackViewPick

TrackViewFilter *filter=NULL

The call back object to filter selection in the track view. See Class TrackViewFilter.

DWORD pickTrackFlags=0

See Track View Picking Flags IDs for a list of possible flags.

Returns

TRUE if the user selected OK to exit the dialog; otherwise FALSE.

Sample Code:

This code brings up the Track View Pick Dialog and filters the input to MAX's controllers. After the controller is selected GetValue() is called on it.

class MyTVFilter : public TrackViewFilter
{
    BOOL proc(Animatable *anim, Animatable *client,int subNum) {
        Control *c = (Control*)anim->GetInterface(I_CONTROL);
        return (c) ? TRUE : FALSE;
    }
};
 
void DoTest()
{
    TrackViewPick res;
    MyTVFilter tvf;
    BOOL okay = IP->TrackViewPickDlg(IP->GetMAXHWnd(), &res, &tvf);
    if (!okay) return;

TrackViewPickMultiDlg()

virtual BOOL TrackViewPickMultiDlg ( HWND  hParent, MaxSDK::Array< TrackViewPick > *  res, TrackViewFilter *  filter = NULL, DWORD  pickTrackFlags = 0  )

pure virtual

Remarks

This methods brings up a dialog that allows one to select multiple tracks. This method works much like the TrackViewPickDlg method above except it is passed a pointer to a table of a TrackViewPick items instead.

Parameters:

HWND hParent

The handle of the parent window.

MaxSDK::Array<TrackViewPick> *res

This is a table (See Template Class Tab) of items chosen by the user. See Class TrackViewPick.

TrackViewFilter *filter=NULL

The call back object to filter selection in the track view. See Class TrackViewFilter.

DWORD pickTrackFlags=0

See Track View Picking Flags IDs for a list of possible flags.

PushCommandMode()

virtual void PushCommandMode ( CommandMode *  m )

pure virtual

Remarks

This method pushes the specified command mode on the stack. Typically this is used by developers handling their own creation using ClassDesc::BeginCreate(). See Class ClassDesc for more details.

Note: This method works as documented but a developer may not want to use it. The problem is that other modes can be pushed on the stack (such as viewport transformation modes) and it becomes complicated to track when it is OK to pop your mode. See the methods below for alternatives (such as SetCommandMode).

Parameters:

CommandMode *m

A pointer to the command mode to push.

SetCommandMode()

virtual void SetCommandMode ( CommandMode *  m )

pure virtual

Remarks

This method sets the top of the stack to the specified command mode. A developer should call DeleteMode() to delete their command mode when done using it.

Parameters:

CommandMode *m

The command mode to set.

PopCommandMode()

virtual void PopCommandMode ( )

pure virtual

Remarks

Pops the command mode off the top of the stack.

GetCommandMode()

virtual CommandMode* GetCommandMode ( )

pure virtual

Remarks

Returns the current mode on the top of the stack.

SetStdCommandMode()

virtual void SetStdCommandMode ( int  cid )

pure virtual

Remarks

This is the typical method called by the developer to handle mouse interaction. It allows the developer to set the command mode to one of the standard command modes. For example: CID_OBJMOVE, CID_OBJROTATE, CID_OBJSCALE, CID_OBJUSCALE, CID_OBJSQUASH, CID_OBJSELECT, etc.

Parameters:

int cid

The index of the command mode to set. See Standard Command Modes to review the full list.

PushStdCommandMode()

virtual void PushStdCommandMode ( int  cid )

pure virtual

Remarks

Allows the developer to push one of the standard command modes on the command stack. For example: CID_OBJMOVE, CID_OBJROTATE, CID_OBJSCALE, CID_OBJUSCALE, CID_OBJSQUASH, CID_OBJSELECT, etc.

Parameters:

int cid

The index of the command mode to set. See Standard Command Modes to review the full list.

RemoveMode()

virtual void RemoveMode ( CommandMode *  m )

pure virtual

Remarks

Removes the specified command mode from the stack. This method pops items off the command mode stack up to and including the specified mode. The top item in the stack is then set as the active command mode. As usual, ExitMode() is called on the specified mode before it is popped and EnterMode() is called on the newly active mode.

Parameters:

CommandMode *m

Points to the command mode to remove.

DeleteMode()

virtual void DeleteMode ( CommandMode *  m )

pure virtual

Remarks

If the developer sets or pushes a command mode, this method should be called when the developer is done with the mode to ensure that it is no longer anywhere in the stack. If the mode is already deleted this method does nothing.

Note: It is normal for a developer to set the 'Select and Move' command mode to be the active one if their mode was at the top of the stack and is being deleted. For instance:

ip->SetStdCommandMode(CID_OBJMOVE);

ip->DeleteMode(&myCMode);

Parameters:

CommandMode *m

The command mode to delete.

GetCurPickMode()

virtual PickModeCallback* GetCurPickMode ( )

pure virtual

Remarks

If a Pick Mode is on top of the command stack, then this function will return the PickModeCallback. If the Pick Mode is not on top of the command stack the it returns NULL.

DoHitByNameDialog()

virtual BOOL DoHitByNameDialog ( HitByNameDlgCallback *  hbncb = NULL )

pure virtual

Remarks

This method is called to put up the standard MAX Hit By Name dialog.

If the callback is NULL this method does a standard select by name. The nodes chosen by the user are selected if the user selects 'Select' from the dialog to exit. Use Interface::GetSelNodeCount() and GetSelNode(i) to retrieve the results.

Parameters:

HitByNameDlgCallback *hbncb=NULL

Points to the callback object. See Class HitByNameDlgCallback. Developers should delete this callback when done.

Returns

TRUE if the user selects 'Select' from the dialog; otherwise FALSE.

ProgressStart()

virtual BOOL ProgressStart ( const MCHAR *  title, BOOL  dispBar, LPTHREAD_START_ROUTINE  fn, LPVOID  arg  )

pure virtual

Remarks

This method puts up a progress bar in the status panel. The function fn is then called and is passed the argument arg. This function fn does the processing work of the plug-in. See the sample code below.

Note: It is not possible to use the progress bar APIs in the create or modify branches of the command panel. In the create or modify branch of the command panel, EndEditParams() gets called from this method. This is because most of MAX is "shut down" during a progress operation. For example, it is not appropriate for users to be moving objects during an IK calculation, or changing the camera lens while a preview is being created (all these operations use the ProgressStart() API). It is for this same reason that the Transform Type-in, Medit, Track View and Video Post windows are hidden during a progress operation. Since EndEditParams() is called, the Interface pointer a plug-in maintains is no longer valid after the operation is started. This method is useful for Utility plug-ins, and Import/Export plug-ins however.

Parameters:

MCHAR *title

The title string for the progress bar to let the user know what is happening.

BOOL dispBar

If FALSE the progress bar is not displayed; if TRUE the progress bar is displayed.

LPTHREAD_START_ROUTINE fn

This is a pointer to a function that returns a DWORD and takes a single argument. When ProgressStart() is called, this function is called with the argument arg passed. This function should be declared as follows:

DWORD WINAPI fn(LPVOID arg)

LPVOID arg

This is the argument to the function fn.

Returns

TRUE means the progress mode was entered successfully. FALSE means that there was a problem. Currently the return value is always TRUE. When compiled for multi-threading (which is turned off in the 1.0 build), FALSE is returned if the new thread could not be created.

Sample Code:

This code demonstrates the use of the ProgressStart(), ProgressEnd() GetCancel() and SetCancel() APIs. There are two ways to use the APIs. One is to use a dummy function for fn in ProgressStart(). Then just call ProgressUpdate() from whatever function you want to do the processing. The other way is to use fn to do the processing.

In this version, the fn function passed to ProgressStart() performs the work.

DWORD WINAPI fn(LPVOID arg)
{
    int i, percent;
    Interface *ip = theUtility.ip;
    for (i = 0; i < 1000; i++) {
        percent = i/10;
        ip->ProgressUpdate(percent);
        if (ip->GetCancel()) {
            switch(MaxSDK::MaxMessageBox(ip->GetMAXHWnd(), _M("Really Cancel"), _M("Question"), MB_ICONQUESTION | MB_YESNO)) {
                case IDYES:
                    return(0);
                case IDNO:
                    ip->SetCancel(FALSE);
            }
        }
    }
    return(0);
}
 
void Utility::Test1()
{
    Interface *ip = theUtility.ip;
    LPVOID arg;
    ip->ProgressStart(_M("Title String"), TRUE, fn, arg);
    ip->ProgressEnd();
}
/endcode
In this version, the fn function passed to ProgressStart() is a dummy function, and the processing is done outside it.
/code
DWORD WINAPI fn(LPVOID arg)
{
    return(0);
}
 
void Utility::Test1()
{
    int i, percent, retval;
    Interface *ip = theUtility.ip;
    LPVOID arg;
    ip->ProgressStart(_M("Title String"), TRUE, fn, arg);
    for (i = 0; i < 1000; i++) {
        percent = i/10;
        ip->ProgressUpdate(percent);
        if (ip->GetCancel()) {
            retval = MaxSDK::MaxMessageBox(ip->GetMAXHWnd(), _M("Really Cancel"), _M("Question"), MB_ICONQUESTION | MB_YESNO);
            if (retval == IDYES)
                break;
            else if (retval == IDNO)
                ip->SetCancel(FALSE);
        }
    }
    ip->ProgressEnd();
}

ProgressUpdate()

virtual void ProgressUpdate ( int  pct, BOOL  showPct = TRUE, const MCHAR *  title = NULL  )

pure virtual

Remarks

This method updates the progress bar. As the function fn passed in ProcessStart() above is working it should periodically call this method to report its progress.

Parameters:

int pct

The percentage complete (0 to 99). This is what causes the progress bar to move.

BOOL showPct = TRUE

If TRUE, then the title parameter is ignored, and a percent is displayed to the right of the progress bar. If FALSE, then the title parameter is displayed next to the progress bar. This is for operations that are discrete – the title might change from "extruding" to "capping" to "welding" for example. Note that currently the Cancel button is not shown if showPct is set to FALSE, however the ESC key may be used to cancel.

MCHAR *title = NULL

If showPct is FALSE, this string is displayed next to the progress bar.

ProgressEnd()

virtual void ProgressEnd ( )

pure virtual

Remarks

This method removes the progress bar and frees the memory that was allocated internally to handle the processing.

GetCancel()

virtual BOOL GetCancel ( )

pure virtual

Remarks

This method returns the progress bar cancel button status. Also see SetCancel() below.

Returns

TRUE if the user pressed the cancel button; otherwise FALSE.

SetCancel()

virtual void SetCancel ( BOOL  sw )

pure virtual

Remarks

Sets the cancelled status returned from GetCancel(). This may be used if you want to give the user a confirmation dialog box asking if they really want to cancel. For example, when a MAX user creates an preview animation this API is used. If the user presses cancel, the preview code reads this via GetCancel(). Then a confirmation dialog is displayed asking the user if they indeed want to cancel. If the user selects that they don't want to cancel, this method is called passing FALSE. This sets the class variable that is returned by GetCancel(). The cancel request is ignored and processing continues.

Note that this will not cancel unless you implement code to process GetCancel(). It merely sets the state returned from GetCancel().

Parameters:

BOOL sw

TRUE to set the cancel flag; FALSE to clear the cancel flag.

CreatePreview()

virtual void CreatePreview ( PreviewParams *  pvp = nullptr, MSTR *  filename = nullptr, MSTR *  snippet = nullptr, MAXScript::ScriptSource  scriptSource = MAXScript::ScriptSource::NotSpecified  )

pure virtual

Remarks

This method is used to render a preview image (or animation) from the currently active viewport using the real-time (viewport) renderer.

Parameters:

PreviewParams *pvp

This class defines the way the preview is generated (via its data members). If NULL, the parameters from the preview rendering dialog box are used. See Class PreviewParams

MSTR *filename

The filename for the preview. If NULL, the filename setting from the preview rendering dialog is used. MSTR *snippet

The MXS code snippet to execute on each frame. The returned string from snippet is displayed in the rendering output. If this value is NULL, the setting in the preview rendering dialog is used.

MAXScript::ScriptSource scriptSource

If snippet is specified, the source of the snippet string.

GetGridSpacing()

virtual float GetGridSpacing ( )

pure virtual

Remarks

This method returns the grid spacing value that the user specifies in the Views / Grid and Snap Settings dialog in the Home Grid tab under Grid Spacing.

Implemented in Interface7.

GetGridMajorLines()

virtual int GetGridMajorLines ( )

pure virtual

Remarks

This method returns the value that the user specifies in the Views / Grid and Snap Settings dialog in the Home Grid tab under Major Lines every Nth.

Implemented in Interface7.

SetExtendedDisplayMode()

virtual void SetExtendedDisplayMode ( int  vflags )

pure virtual

Remarks

This method is used internally to set the extended display mode.

Parameters:

int vflags

See Extended Display Modes.

GetExtendedDisplayMode()

virtual int GetExtendedDisplayMode ( )

pure virtual

Remarks

Returns the extended display mode flags. This method provides a mechanism to retrieve some additional information about an object that is more dependent on MAX than on the particular object. For example, when a spotlight is selected, it can use this method to detect that it is the only item selected, and display its cone. It checks this using and extended display mode EXT_DISP_ONLY_SELECTED. See Extended Display Modes.

SetFlyOffTime()

virtual void SetFlyOffTime ( int  msecs )

pure virtual

Remarks

This sets the custom control flyoff time to the value passed. This is the number of milliseconds the user must hold down on a flyoff button before the flyoff is activated.

Parameters:

int msecs

The number of milliseconds the user must hold down on the button before the flyoff is activated.

GetFlyOffTime()

virtual int GetFlyOffTime ( )

pure virtual

Remarks

Returns the number of milliseconds the user must hold down on a flyoff button before the flyoff is activated.

GetSysCursor()

virtual HCURSOR GetSysCursor ( int  id )

pure virtual

Remarks

This method returns the cursor handle for the standard MAX cursors. Use SetCursor() from the Windows API to set the cursor.

Parameters:

int id

One of the following values:

SYSCUR_MOVE, SYSCUR_ROTATE, SYSCUR_USCALE, SYSCUR_NUSCALE,

SYSCUR_SQUASH, SYSCUR_SELECT, SYSCUR_DEFARROW.

Returns

The handle of the cursor.

SetCrossHairCur()

virtual void SetCrossHairCur ( BOOL  onOff )

pure virtual

Remarks

This method is reserved for future use.

GetCrossHairCur()

virtual BOOL GetCrossHairCur ( )

pure virtual

Remarks

This method is reserved for future use.

RealizeParamPanel()

virtual void RealizeParamPanel ( )

pure virtual

SnapAngle()

virtual float SnapAngle ( float  angleIn, BOOL  fastSnap = TRUE, BOOL  forceSnap = FALSE  )

pure virtual

Remarks

Normally, with angle snap off, interactive rotation of a node uses a rate of 1/2 degree per pixel. With angle snap on, the angles are snapped to the nearest MAX angle snap value.

This method may be used when interactive rotation is taking place with the mouse to snap the angle passed to the nearest MAX angle snap value. In this method, the input value/output value snap correspondence is accelerated as the angle grows. This prevents the user from having to move the mouse too much with larger angle values. This is why this method does not return a linear relationship between the input angle and the snapped output angle.

Note that when angle snap is off, this method just returns the input value unaltered.

Note for R3: This method formerly was set up with a single parameter, the angle to be snapped. If the angle snap toggle was on, snapping occurred. If not, it did nothing. There were two problems with this:

1) A multiplier was applied to the angle input, giving faster interactive results in object rotations, etc. This had a negative effect if you just wanted your input angle snapped to the nearest snap angle.

2) It only snapped if the angle snap toggle was on. Sometimes, you might want to snap something to the angle snap value even if the primary toggle was off.

To remedy these shortcomings, the method has had two parameters added (fastSnap and forceSnap).

Parameters:

float angleIn

Angle to snap in radians.

BOOL fastSnap=TRUE

If TRUE the snapping multiplier is used; if FALSE it is not.

BOOL forceSnap=FALSE

If TRUE snapping is used even if the primary angle snap toggle is off.

Returns

Angle snapped to the nearest angle snap setting (considering acceleration if specified), in radians, to be used for interactive rotation.

SnapPercent()

virtual float SnapPercent ( float  percentIn )

pure virtual

Remarks

Given a value in the range 0.0 (0%) to 1.0 (100%) this method snaps the value using the current percentage snap.

Parameters:

float percentIn

The value to snap.

Returns

The snapped value where 0.0 = 0% and 1.0 = 100%.

GetSnapState()

virtual BOOL GetSnapState ( )

pure virtual

Remarks

Retrieves the snap toggle state.

Returns

TRUE if snap is on; FALSE if snap is off.

GetSnapMode()

virtual int GetSnapMode ( )

pure virtual

Remarks

Retrieves the current snap type.

Returns

One of the following values:

SNAPMODE_RELATIVE

SNAPMODE_ABSOLUTE

SetSnapMode()

virtual BOOL SetSnapMode ( int  mode )

pure virtual

Remarks

Set the current snap mode. Note that setting the mode to SNAPMODE_ABSOLUTE will fail if the reference coordinate system is not in set to Screen.

Parameters:

int mode

One of the following values:

SNAPMODE_RELATIVE

SNAPMODE_ABSOLUTE

Returns

Returns TRUE if succeeded; otherwise FALSE.

SetPickMode()

virtual void SetPickMode ( PickModeCallback *  pCB )

pure virtual

Remarks

This will set the command mode to a standard pick mode. The callback implements hit testing and a method that is called when the user actually picks an item. Note that this method, if called a second time, will cancel the pick mode and put the user into 'Select and Move' mode. This can be used to handle the case where a user clicks on a user interface control a second time to cancel to picking.

Sample code using this API is available in /MAXSDK/SAMPLES/OBJECTS/MORPHOBJ.CPP. A utility plug-in that uses this API is /MAXSDK/SAMPLES/UTILITIES/ASCIIOUT.CPP.

Parameters:

PickModeCallback *pCB

A pointer to an instance of the class PickModeCallback.

ClearPickMode()

virtual void ClearPickMode ( )

pure virtual

Remarks

This method is called to make sure there are no pick modes in the command stack.

PickNode()

virtual INode* PickNode ( HWND  hWnd, IPoint2  pt, PickNodeCallback *  filt = NULL  )

pure virtual

Remarks

This method hit tests the screen position for nodes and returns an INode pointer if one is hit, NULL otherwise.

Parameters:

HWND hWnd

Handle of the window to check.

IPoint2 pt

Point to check in screen coordinates.

PickNodeCallback *filt=NULL

This callback may be used to filter nodes from being picked. See Class PickNodeCallback.

Returns

INode pointer of node that was hit; NULL if no node was found.

BoxPickNode()

virtual void BoxPickNode ( ViewExp *  vpt, IPoint2 *  pt, BOOL  crossing, PickNodeCallback *  filt = NULL  )

pure virtual

Remarks

This method performs a node level hit test on the specified rectangular region. Use either the ViewExp::GetClosestHit() or ViewExp::GetHit() method to access the result.

Parameters:

ViewExp *vpt

The viewport to perform the hit testing.

IPoint2 *pt

These points specify the box region to hit test. The first point in the array is the lower left. The second point is the upper right.

BOOL crossing

If TRUE Crossing selection is used; otherwise Window selection is used.

PickNodeCallback *filt=NULL

This callback may be used to filter nodes from being picked. See Class PickNodeCallback.

CirclePickNode()

virtual void CirclePickNode ( ViewExp *  vpt, IPoint2 *  pt, BOOL  crossing, PickNodeCallback *  filt = NULL  )

pure virtual

Remarks

This method performs a node level hit test on the specified circular region. Use either the ViewExp::GetClosestHit() or ViewExp::GetHit(int i) method to access the result.

Parameters:

ViewExp *vpt

The viewport to perform the hit testing.

IPoint2 *pt

These points specify the circular region to hit test. The first point in the array is the center. The second point is a point on the radius.

BOOL crossing

If TRUE Crossing selection is used; otherwise Window selection is used.

PickNodeCallback *filt=NULL

This callback may be used to filter nodes from being picked. See Class PickNodeCallback.

FencePickNode()

virtual void FencePickNode ( ViewExp *  vpt, IPoint2 *  pt, BOOL  crossing, PickNodeCallback *  filt = NULL  )

pure virtual

Remarks

This method performs a node level hit test on the specified arbitrary polygonal region. Use either the ViewExp::GetClosestHit() or ViewExp::GetHit() method to access the result.

Parameters:

ViewExp *vpt

The viewport to perform the hit testing.

IPoint2 *pt

These points specify the fence region to hit test. It is assumed the last point is connected to the first point to close the region. The fence knows when it's out of points when it hits a point that has negative x and y values. So, the initializer IPoint2(-1, -1) added to the bottom of this IPoint2 list signals the end.

BOOL crossing

If TRUE Crossing selection is used; otherwise Window selection is used.

PickNodeCallback *filt=NULL

This callback may be used to filter nodes from being picked. See Class PickNodeCallback.

RegisterSubObjectTypes()

virtual void RegisterSubObjectTypes ( const MCHAR **  types, int  count, int  startIndex = 0  )

pure virtual

Remarks

This method registers the sub-object types for a given plug-in object type. See the Advanced Topics section on ~{ sub-object selection }~ for more details.

Parameters:

const MCHAR **types

Array of strings listing the sub object levels. The order the strings appear in the array sets the indices used for the sub-object levels. Level 0 is always object level, the first string corresponds to level 1, and the second string corresponds to level 2, etc. In the sample code below, "Center" is level 1 and "Gizmo" is level 2.

int count

The number of strings in the array.

int startIndex=0

Specifies which string to display initially in the sub-object type combo box. This is needed because the NURBS object computes its sub-object list dynamically, and sometimes it add a new sub-object level while already in a sub-object level. The default value of zero replicates the original behavior.

Sample Code:

const MCHAR *ptype[] = { _M("Center"), _M("Gizmo") };

ip->RegisterSubObjectTypes(ptype, 2);

AppendSubObjectNamedSelSet()

virtual void AppendSubObjectNamedSelSet ( const MCHAR *  set )

pure virtual

Remarks

A modifier may call this method to add sub-object named selection sets to the named selection set drop down list in the MAX toolbar. This should be done whenever the selection level changes (in the Modifiers BaseObject::ActivateSubobjSel() method). See Class BaseObject for additional methods associated with sub-object named selection sets.

Parameters:

const MCHAR *set

The named selection set to add to the list.

ClearSubObjectNamedSelSets()

virtual void ClearSubObjectNamedSelSets ( )

pure virtual

Remarks

This method clears the named sub-object selection sets from the drop down.

ClearCurNamedSelSet()

virtual void ClearCurNamedSelSet ( )

pure virtual

Remarks

This method clears the current edit field of the named selection set drop down.

SetCurNamedSelSet()

virtual void SetCurNamedSelSet ( const MCHAR *  setName )

pure virtual

Remarks

Sets the edit field of the named selection set drop down to the set whose name is passed.

Parameters:

MCHAR *setName

The name of the selection set to make current.

NamedSelSetListChanged()

virtual void NamedSelSetListChanged ( )

pure virtual

Remarks

Calling this method tells the system that the named sub-object selection sets have changed and that the drop down needs to be rebuilt. This will cause BaseObject::SetupNamedSelDropDown() to be called on the current item being edited. This is often called inside restore objects that undo changes to the selection set. This causes the system to check if the current item being edited is in sub-object selection mode, and if so, will cause SetupNamedSelDropDown() to be called. Note that restore objects can be invoked at any time and the user may not be in sub-object selection mode (for instance they might be in the Display panel). Restore objects however can simply call this method and the system will figure out if the drop down needs to be updated.

GetSubObjectLevel()

virtual int GetSubObjectLevel ( )

pure virtual

Remarks

Returns the state of the sub object drop-down.

Returns

0 is object level and >= 1 refers to the levels registered by the object using RegisterSubObjectTypes(). The value refers to the order the item appeared in the list. 1 is the first item, 2 is the second, etc.

SetSubObjectLevel()

virtual void SetSubObjectLevel ( int  level, BOOL  force = FALSE  )

pure virtual

Remarks

Sets the sub-object drop down. This will cause the object being edited to receive a notification that the current sub-object level has changed (via BaseObject::ActivateSubobjSel()).

Parameters:

int level

The level registered by the object using RegisterSubObjectTypes(). 0 indicates object level. Values greater than 1 refer to the order the items appeared in the list.

BOOL force = FALSE

If this parameter is TRUE, this method will set the level even if the current level is the same as the level requested. This is to support objects that change sub-object levels on the fly, for instance NURBS.

GetNumSubObjectLevels()

virtual int GetNumSubObjectLevels ( )

pure virtual

Remarks

This method returns the number of sub object levels that the currently edited object (or modifier) has. Like the other sub-object related methods in this class, this method will only return a valid answer if the modifier panel is displayed.

PipeSelLevelChanged()

virtual void PipeSelLevelChanged ( )

pure virtual

Remarks

Plug-ins call this method to notify the system that the selection level in the pipeline has changed. The selection level flows up the pipeline so if you change the selection level you affect things later in the pipeline. For example an edit modifier that changes the sub-object level from vertex to object level must call this method after making the change to notify the system. Note that it is only called for modifiers whose sub-object levels propagate up the pipeline. For example, when entering a sub-object level within the Bend modifier, PipeSelLevelChanged() is not called.

This method should be called from within ActivateSubobjSel() to notify the system that a selection level has changed in the pipeline. Note that calling this method from within ModifyObject() is no good since it involves re-evaluating the pipeline, which will call ModifyObject(), which will the call PipeSelLevelChanged() again, etc.

GetPipelineSubObjLevel()

virtual void GetPipelineSubObjLevel ( DWORDTab &  levels )

pure virtual

Remarks

Gets the sub-object selection level at the point in the pipeline just before the current place in the history.

Parameters:

DWORDTab &levels

The sub-object level. This value depends on the object. The only level defined is level 0, which means 'object' level selection.

SubObHitTest()

Parameters:

TimeValue t

The time of the hit testing.

int type

The hit test type. See Scene and Node Hit Test Types. int crossing

Nonzero for crossing selection; 0 for normal (window).

int vflags

The flags for hit testing. See Scene and Node Hit Testing Flags IPoint2 *p

Point to check in screen coordinates.

ViewExp *vpt

An interface pointer that may be used to call methods associated with the viewports.

Returns

Nonzero if the item was hit; otherwise 0.

GetModContexts()

virtual void GetModContexts ( ModContextList &  list, INodeTab &  nodes  )

pure virtual

Remarks

A modifier may be applied to several objects in the scene. This method retrieves a list of all the ModContexts for the modifier at the current place in the modifier stack. It also gets a list of the nodes the modifier is applied to. For example a modifier may store data into the local data portion of the ModContext for each object affected by the modifier. In order to get at this data it needs to get each ModContext.

Note: this method returns only the ModContext of the currently selected objects, even if the modifier is applied to several objects.

Parameters:

ModContextList& list

A reference to the list of ModContexts. See Class ModContextList.

INodeTab& nodes

A reference to the table of each of the nodes. See Class INodeTab.

InProgressiveMode()

virtual bool InProgressiveMode ( )

pure virtual

Remarks

Returns TRUE is 3ds Max is in progressive mode. See BeginProgressiveMode().

BeginProgressiveMode()

virtual void BeginProgressiveMode ( )

pure virtual

Remarks

Turns on progressive mode for SetNodeTM().

In certain situations, a time sequence of matrices is computed and sent to the node via INode::SetNodeTM(TimeValue t, const Matrix3& tm). If the node employs the standard PRS controller and the rotation is the standard Euler XYZ controller, 3ds Max can achieve better animation results if it computes euler angles at the current frame based on those from the previous frame. Progressive mode tells the Euler controller to derive angles based on the previous frame. It is assumed that in this mode, SetNodeTM() is called in a strictly forward time order.

Usage:

GetCOREInterface()->BeginProgressiveMode();

for (t = start_time, t < end_time; t += time_per_frame) {

node.SetNodeTM(t, tm_at_t);

}

GetCOREInterface()->EndProgressiveMode();

To test whether 3ds Max is currently in progressive mode, use:

if ( GetCOREInterface()->InProgressiveMode() )...

EndProgressiveMode()

virtual void EndProgressiveMode ( )

pure virtual

Remarks

Turns off progressive mode. See BeginProgressiveMode().

pure virtual

Remarks

This method is used to add a rollup page to the command panel. It returns the window handle of the rollup page.

Parameters:

HINSTANCE hInst

The DLL instance handle of the plug-in.

MCHAR *dlgTemplate

The dialog template for the rollup page.

DLGPROC dlgProc

The dialog proc to handle the messages sent to the rollup page.

MCHAR *title

The title displayed in the title bar of the rollup page.

LPARAM param=0

Any specific data to pass along may be stored here. This may be later retrieved using the GetWindowLong() call from the Windows API if it was set in the window using SetWindowLong().

For example, at the beginning of the dialog proc do something like:

BOOL CALLBACK MyDlgProc(

HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {

MyUtil *u = (MyUtil *)GetWindowLong(hWnd, GWL_USERDATA);

if (!u && message != WM_INITDIALOG ) return FALSE;

. . .

Then inside the code block handling the WM_INITDIALOG message do something like:

switch (message)
{
    case WM_INITDIALOG:
        u = (MyUtil *)lParam;
        SetWindowLong(hWnd, GWL_USERDATA, (LONG)u);
        . . .

Then later in the dialog you can access the object passed in – in the case above an instance of MyUtil (using u->).

DWORD rollUpFlags=0

The following flag value may be used:

APPENDROLL_CLOSED

Starts the page in the rolled up (closed) state.

int category = ROLLUP_CAT_STANDARD

The category parameter provides flexibility with regard to where a particular rollup should be displayed in the UI. RollupPanels with lower category fields will be displayed before RollupPanels with higher category fields. For RollupPanels with equal category value the one that was added first will be displayed first. Although it is possible to pass any int value as category there exist currently 5 different category defines: ROLLUP_CAT_SYSTEM, ROLLUP_CAT_STANDARD, and ROLLUP_CAT_CUSTATTRIB.

When using ROLLUP_SAVECAT, the rollup page will make the provided category sticky, meaning it will not read the category from the RollupOrder.cfg file, but rather save the category field that was passed as argument in the CatRegistry and in the RollupOrder.cfg file.

The method will take the category of the replaced rollup in case the rollUpFlags argument contains ROLLUP_USEREPLACEDCAT. This is mainly done, so that this system works with param maps as well.

Sample Code:

hBendParams = ip->AddRollupPage(hInstance, MAKEINTRESOURCE(IDD_BEND_ROLLUP), BendParamDialogProc,_M("Parameters"), (LPARAM)this );

Returns

The window handle of the rollup page.

Remarks

This method allows hand cursor scrolling in the command panel when the user clicks and drags the mouse in an unused area of the dialog. When the user mouse-es down in dead area of the command panel, the plug-in should pass mouse messages to this function which will pass them on to the rollup.

Note: This method is obsolete in MAX 2.0 and later. These messages no longer need to be passed along as this is handled internally.

Parameters:

HWND hDlg

The window handle of the dialog.

UINT message

The message sent to the dialog proc.

WPARAM wParam

Passed in to the dialog proc. Pass along to this method.

LPARAM lParam

Passed in to the dialog proc. Pass along to this method.

Sample Code:

case WM_LBUTTONDOWN: case WM_LBUTTONUP: case WM_MOUSEMOVE:
    ip->RollupMouseMessage(hDlg,message,wParam,lParam);

BOOL redraw=TRUE

If set to FALSE, the current time will be set to the specified time but the viewports will not be redrawn.

GetAnimRange()

virtual Interval GetAnimRange ( )

pure virtual

Remarks

pure virtual

Remarks

Registers a callback object that will get called every time the current animation time is changed.

Parameters:

TimeChangeCallback *tc

Points to the callback object to register. See Class TimeChangeCallback.

UnRegisterTimeChangeCallback()

virtual void UnRegisterTimeChangeCallback ( TimeChangeCallback *  tc )

pure virtual

Remarks

Points to the callback object to un-register. See Class CommandModeChangedCallback.

RegisterViewportDisplayCallback()

virtual void RegisterViewportDisplayCallback ( BOOL  preScene, ViewportDisplayCallback *  cb  )

pure virtual

Remarks

Registers a ViewportDisplayCallback whose Display() method will be called to allow a plug-in to draw in the MAX viewports.

Parameters:

BOOL preScene

If TRUE the callback will be called before objects are rendered (typically, but not always); if FALSE the callback is called after the objects are rendered.

In some cases redrawing the viewports may take two passes; once to re-render the background plane and once to re-render the foreground plane. In this case the order of events would be:

Call pre callbacks

Render scene

Call post callbacks

Call pre callbacks

Render scene

Call post callbacks

The two calls to callbacks in the middle are neither pre nor post callbacks. However you could also look at this as two separate redraws.

ViewportDisplayCallback *cb

Points to the callback object. See Class ViewportDisplayCallback.

UnRegisterViewportDisplayCallback()

virtual void UnRegisterViewportDisplayCallback ( BOOL  preScene, ViewportDisplayCallback *  cb  )

pure virtual

Remarks

Call this method to un-register the viewport display callback object.

Parameters:

BOOL preScene

If TRUE the callback will be called before object are rendered (typically, but not always); if FALSE the callback is called after the objects are rendered.

ViewportDisplayCallback *cb

Points to the callback object. See Class ViewportDisplayCallback.

NotifyViewportDisplayCallbackChanged()

virtual void NotifyViewportDisplayCallbackChanged ( BOOL  preScene, ViewportDisplayCallback *  cb  )

pure virtual

Remarks

This method is called to inform MAX that the viewport callback has changed. This is similar to when an object that is part of the reference hierarchy changes and it needs to call NotifyDependents() with the message REFMSG_CHANGE to inform the items that depend on it. In a sense a ViewportDisplayCallback is like an object in the scene in that it has a Display() method that is called. However, the callback is not actually an object that is part of the reference hierarchy so it cannot send a REFMSG_CHANGE message when it changes. So this method provides the equivalent functionality. If the callback changes this method needs to be called.

To understand why this is needed consider that if a plug-in called RedrawViews() five times in a row, the viewports may be redrawn the first time (if something has changed), but the next four calls won't do anything. This is because MAX maintains some flags that indicate if things have changed or not and these flags are reset on the first redraw to indicate that everything is up to date. Therefore, when a ViewportDisplayCallback changes, it needs to call this method to let MAX know that changes have been made and the viewports indeed need to be redrawn the next time RedrawViews() is called.

Parameters:

BOOL preScene

If TRUE the callback will be called before objects are rendered (typically, but not always); if FALSE the callback is called after the objects are rendered.

ViewportDisplayCallback *cb

Points to the callback object. See Class ViewportDisplayCallback.

RegisterExitMAXCallback()

virtual void RegisterExitMAXCallback ( ExitMAXCallback *  cb )

pure virtual

Remarks

Registers a ExitMAXCallback whose Exit() method will be called when MAX is about to exit. The return value from the callback allows the plug-in to decide if MAX exits or not.

Parameters:

ExitMAXCallback *cb

Points to the callback object. See Class ExitMAXCallback.

UnRegisterExitMAXCallback()

virtual void UnRegisterExitMAXCallback ( ExitMAXCallback *  cb )

pure virtual

Remarks

Un-registers the exit callback so it's no longer called.

Parameters:

ExitMAXCallback *cb

Points to the callback object. See Class ExitMAXCallback.

GetRightClickMenuManager()

virtual RightClickMenuManager* GetRightClickMenuManager ( )

pure virtual

Remarks

Using this pointer a developer can add to the menu that pops ups when the user clicks the right mouse button. Example code is available in: /MAXSDK/SAMPLES/MODIFIERS/EDITSPL.CPP.

See also

Class RightClickMenuManager.

Returns

A pointer to the RightClickMenuManager.

RegisterDeleteUser()

virtual void RegisterDeleteUser ( EventUser *  user )

pure virtual

Remarks

Registers a callback invoked when the user presses the Delete Key. This allows the developer to override the default processing of the Delete Key.

Parameters:

EventUser *user

Pointer to an instance of the EventUser class.

Sample Code:

See /MAXSDK/SAMPLES/MODIFIERS/EDITSPL.CPP.

UnRegisterDeleteUser()

virtual void UnRegisterDeleteUser ( EventUser *  user )

pure virtual

Remarks

Un-registers a Delete Key callback.

Parameters:

EventUser *user

Pointer to an instance of the EventUser class.

MakeNameUnique()

virtual void MakeNameUnique ( MSTR &  name )

pure virtual

Remarks

Generates node names that are unique within the current scene. Given a name, this method will modify it to ensure it's unique. It does this by appending a unique numeric suffix to the end of the name. Notes:

• Calling this method repeatedly with the same original name that is not used by any node in the scene, it will return each time the same name. So, for a node name to be considered by this method as being in use, the node needs to be in the current scene.
• Names of scene xrefed nodes are not considered as being part of the current scene.
• Calling this method after Interface::CreateObjectNode(Object*) can result in the name suffix to be greater than the value expected by the client code. For example, if Box001 already exists in the scene, calling Interface::CreateObjectNode(Object*) to create a new Box object, then calling Interface::MakeNameUnique() to create a unique name for it, will yield Box003 as new unique name, while Box002 should be the correct new name. The solution is to either call Interface::CreateObjectNode(Object*) only, which will create a new name, or first call Interface::MakeNameUnique() with a root name and then call Interface::CreateObjectNode(Object*, const MCHAR*) to create the object with the desired new name. See also class NameMaker for ways to create unique names for other scene entities than nodes, such as layers, materials, etc.

Parameters:

MSTR &name

The name to make unique. Any existent numeric suffix is stripped before the name is made unique.

CreateObjectNode()

virtual INode* CreateObjectNode ( Object *  obj )

pure virtual

Remarks

Creates a new node in the scene with the given object. Normally a developer will use the standard creation methods for procedural objects and this method is not used. However if the developer wants to handle the creation process on their own they may need to use this method.

See also

Object Creation Methods.

Parameters:

Object *obj

Pointer to the Object to create.

Returns

Pointer to the node created. See also Interface::CreateObjectNode(Object*, const MCHAR*)

Returns

Pointer to the camera object created.

CreateTargetObject()

virtual Object* CreateTargetObject ( )

pure virtual

Remarks

Creates a new node in the scene with the given object. Normally a developer will use the standard creation methods for procedural objects and this method is not used. However if the developer wants to handle the creation process on their own they may need to use this method.

See also

Object Creation Methods.

Parameters:

Object *obj

Pointer to the Object to create.

Returns

Pointer to the node created. See also Interface::CreateObjectNode(Object*, const MCHAR*)

CreateLightObject()

virtual GenLight* CreateLightObject ( int  type )

pure virtual

Remarks

Creates a new node in the scene with the given object. Normally a developer will use the standard creation methods for procedural objects and this method is not used. However if the developer wants to handle the creation process on their own they may need to use this method.

See also

Object Creation Methods.

Parameters:

Object *obj

Pointer to the Object to create.

Returns

Pointer to the node created. See also Interface::CreateObjectNode(Object*, const MCHAR*)

CreateInstance()

virtual void* CreateInstance ( SClass_ID  superID, Class_ID  classID  )

pure virtual

Remarks

Creates an instance of a registered class. This will call Create() on the class descriptor.

Parameters:

SClass_ID superID

The super class ID of the item to create an instance of.

Class_ID classID

The class ID of the item to create an instance of. See Class Class_ID.

Returns

Pointer to the created instance.

Note:

There is a global method that duplicates the functionality of this class method to let you create an instance of any registered class wherever you are (without the interface pointer):

void* CreateInstance(SClass_ID superID, Class_ID classID);

BindToTarget()

virtual int BindToTarget ( INode *  laNode, INode *  targNode  )

pure virtual

Remarks

This method binds a node to a target using a lookat controller.

Parameters:

INode *laNode

Pointer to the node to assign the lookat controller to.

INode *targNode

Pointer to the target node.

Returns

Returns TRUE if the node was bound; otherwise FALSE.

Sample Code:

This method is used in /MAXSDK/SAMPLES/OBJECTS/CAMERA.CPP.

IsCPEdgeOnInView()

virtual int IsCPEdgeOnInView ( )

pure virtual

Remarks

This method returns nonzero if the construction plane is 'head on' in the current viewport. For example if the construction plane was XY and you were looking from the Front view, this method would return nonzero. This is used for example during object creation because this process doesn't work very well when the view is 'head on'.

Returns

Nonzero if the construction plane is 'head on' in the current viewport; otherwise 0.

For use with extended views: - make the extended viewport active (set on mouse click, for example) -put up the view type popup menu (put up on right-click, for example)

DeleteNode()

virtual unsigned int DeleteNode ( INode *  node, BOOL  redraw = TRUE, BOOL  overrideDriven = FALSE  )

pure virtual

Deletes the specified node from the scene.

Call this method to delete a specific node from the scene.

• The children of the deleted node will maintain their position.
• Empty group heads resulting from the deletion of the node will also be deleted.
• System nodes are not deleted by this method. Use the system's methods to modify its node structure. Use Interface9::DeleteNodes to delete all nodes of a system object.
• The selection state and deletion of the node will be undo-able after calling this method, provided that the undo system was engaged. For example, to delete the first node in the current selection set, one could use the following code:

  theHold.Begin();
  Interface* ip = GetCOREInterface()
  ip->DeleteNode(ip->GetSelNode(0));
  theHold.Accept(_M("Delete"));

  The string used in the Accept() method appears in the undo list.

Note that the object reference of the node is deleted as well if the only item referencing that object is the node. This is because when the node is deleted, it first deletes all its references. Whenever a reference is deleted, if the item is the last reference, then the system deletes the item as well. If the node deletion occurs while the undo system was engaged, RestoreObjs will hold references to the items removed from the node, preventing their immediate deletion.

Parameters

[in]	node	The node to be deleted
[in]	redraw	If FALSE the viewports will not be redrawn after the node is deleted. This allows several nodes to be deleted at once without the viewports having to be redrawn after each one.
[in]	overrideDriven	If TRUE, this method will delete nodes whose TM controllers implement Control::PreventNodeDeletion() to return TRUE. Control::PreventNodeDeletion() controls whether the node can be deleted from the scene. This parameter allows a driver controller to easily delete driven nodes if it needs to.

Returns

The number of nodes that were deleted.

GetRootNode()

virtual INode* GetRootNode ( )

pure virtual

Remarks

Returns a pointer to the root node. From the root node one can retrieve the children (using INode::NumberOfChildren(), and INode::GetChildNode(i)). This allows a developer enumerated the scene by enumerating the node tree.

SetNodeTMRelConstPlane()

virtual void SetNodeTMRelConstPlane ( INode *  node, Matrix3 &  mat  )

Parameters:

INode *node

The node whose transform will be set.

Matrix3& mat

The transformation matrix.

SelectNode()

virtual void SelectNode ( INode *  node, int  clearSel = 1  )

pure virtual

Remarks

This selects the specified node, either adding it to the current selection set, or creating a new selection set with the node.

Note: A developer should call theHold.Begin() before this method and theHold.Accept() after this call. Otherwise, MAX may crash if the user selects undo after this call has been issued. See the sample code below. Also see The Undo and Redo System for more details on this system.

Parameters:

INode *node

The node to select.

int clearSel = 1

If zero, the node is added to the current selection set. If nonzero, the node replaces the selection set.

Sample Code:

theHold.Begin();
ip->SelectNode(node);
MSTR undostr; undostr.printf("Select");
theHold.Accept(undostr);

GetActiveGrid()

virtual INode* GetActiveGrid ( )

pure virtual

Remarks

Returns the active grid node or NULL if the home grid is in use.

StopCreating()

virtual void StopCreating ( )

pure virtual

Remarks

Calling this method will result in ending the currently active object creation mode. The plugin's ClassDesc::EndCreate() method will also be called as a result of calling StopCreating(). Most often this method is called either from custom creation command modes in response to a change in the current object selection, or from functions that need to change the current object selection and could be invoked virtually any time, such as via a hot-key or MAXScript. Note that this method should not be called from within an object's creation callback in order to stop creating the current object. Rather, CREATE_STOP should be returned from the creation callback procedure. For more information, see Object Creation Methods.

NonMouseCreate()

virtual Object* NonMouseCreate ( Matrix3  tm )

pure virtual

Remarks

This creates a new object/node without going through the usual create mouse proc sequence. The matrix is relative to the construction plane. This must be called during the creation phase of an object. For example, the procedural sphere uses it when the user clicks on the 'Create' button after they type in the parameters for the sphere. See Object Creation Methods.

Parameters:

Matrix3 tm

The transformation matrix relative to the construction plane.

NonMouseCreateFinish()

virtual void NonMouseCreateFinish ( Matrix3  tm )

pure virtual

Remarks

This method is presently only used in the Line object. It's used for repositioning the pivot point of the object at the end of the creation process. You simply pass it the new matrix, and the creation manager sets the TM for the node being created to the given TM * the construction plane TM.

Parameters:

Matrix3 tm

The transformation matrix relative to the construction plane for the node.

Pointer to the table of nodes to 'flash'.

Sample Code:

INodeTab flash;
INode *node;
for (int i=0; i<ip->GetSelNodeCount(); i++)

}
ip->FlashNodes(&flash);

TranslateAndDispatchMAXMessage()

virtual void TranslateAndDispatchMAXMessage ( MSG &  msg )

pure virtual

Remarks

If a plug-in needs to do a PeekMessage() and wants to actually remove the message from the queue, it can use this method to have the message translated and dispatched.

Parameters:

MSG &msg

The message from PeekMessage().

CheckMAXMessages()

virtual BOOL CheckMAXMessages ( )

pure virtual

Remarks

This will go into a PeekMessage() loop until there are no more messages left. This is a way a plug-in can relieve control to the system.

There may be certain circumstances where a plug-in wants to give control back to MAX. For example a plug-in may put up a progress bar with a cancel button during a lengthy operation. However the cancel button would not receive any messages if the user was clicking on it because no messages are being dispatched.

This method will relieve control and let any messages that are in the queue get processed. If there are no messages it will return right away. This provides a way for a plug-in to yield control.

Note: A developer must be prepared to handle a lot of different conditions if this is done. For example the user could click on the delete key and delete the object that was being processed. EndEditParams() could be called on the plug-in. So in EndEditParams() there must be some logic to signal the other lengthy process that EndEditParams() was called.

Returns

If this method returns FALSE then the user is attempting to quit MAX and the caller should return.

As shown above, this method does not automatically set the values for envMap and atmos. You must do this manually if you are using the RendParams object to initialize the renderer. Then you can call Renderer::Open(..., rp, ...). In MAX 2.0 and later, atmos and envMap are properly initialized without the above code.

Parameters:

RendParams &rp

This is the class instance whose data is filled in. See Class RendParams.

ViewExp *vpt

This pointer only needs to be passed in if the RendType is RENDTYPE_REGION or RENDTYPE_BLOWUP. In these cases it will set up the RendParams regxmin, regxmax, regymin, regymax from values stored in the viewport.

pure virtual

Remarks

This method returns an instance of the ITrackBar class. This class may be used to manipulate the track bar. See Class ITrackBar.

SetIncludeXRefsInHierarchy()

virtual void SetIncludeXRefsInHierarchy ( BOOL  onOff )

pure virtual

Remarks

This method allows a plug-in to specify whether scene XRef objects are hidden from the hierarchy when it is traversed. Normally this parameter is set to FALSE except during rendering. If a plug-in wants access to XRef scene objects then it should set this to TRUE and traverse the scene and then set it back to FALSE when it's done.

Most of the time the XRef trees (whose root node is a child of the client scene's root node) are skipped when traversing the hierarchy. When this option is turned on, all root nodes will include child XRef scene root nodes in any traversal related functions such as NumberOfChildren() and GetChildNode(i).

This option is turned on automatically before rendering and turned off after so that scene XRefs appear in the production renderer. Note: This option should not be left on if it is turned on since it would cause scene XRef objects to be accessible to the user in the client scene.

Note that plug-ins can also access XRef objects using the Class INode XRef methods.

Parameters:

BOOL onOff

TRUE to include XRefs in the hierarchy; FALSE to not include them.

GetIncludeXRefsInHierarchy()

virtual BOOL GetIncludeXRefsInHierarchy ( )

pure virtual

Remarks

Returns TRUE if XRefs are included in the traversal of the scene hierarchy; otherwise FALSE. See the method above for details.

IsXRefAutoUpdateSuspended()

virtual BOOL IsXRefAutoUpdateSuspended ( )

pure virtual

Remarks

Returns TRUE if the automatic updating of XRefs is suspended; otherwise FALSE. When an XRef file is changed and that causes an XRef object to update, the old XRef object gets deleted from memory which can cause problems for some plug-ins. For example, the Dynamics system would have a problem if an update occurred while a solution was solving. This method is used to disable the automatic updating to prevent the problem.

SetXRefAutoUpdateSuspended()

virtual void SetXRefAutoUpdateSuspended ( BOOL  onOff )

CaptureSubObjectRegistration()

virtual bool CaptureSubObjectRegistration ( bool  OnOff, Class_ID  cid  )

pure virtual

Remarks

This method is used to lock and unlock subobject mode registrations and is primarily used by the FileLink wrapper classes acting as proxies to other classes in 3D Studio VIZ. When a class calls this method with OnOff set to TRUE, then other classes are prevented from registering new subobject modes. This continues until the original class "releases" by calling CaptureSubObjectModes(FALSE, myClassID). The second argument insures that only the class which does the capture can do the release. Note that this is used only by certain VIZ plugins.

Parameters:

bool OnOff

TRUE to prevent other classes from registering new subobject modes.

Class_ID cid

The class ID.

Returns

TRUE is successful, otherwise FALSE.

Returns

TRUE if successful, otherwise FALSE.

GetImportCtxNode()

virtual INode* GetImportCtxNode ( void  )

pure virtual

Remarks

On drag-and-drop, if the drop type is a file, the drop handler searches for an importer plugin that can handle the file (based on its extension). Some drop operations, such as bitmaps and material XML files, can or must be dropped on to an object in the scene.

Returns

The node that the operation is performed on, if one is "hit" at the drop location. It returns NULL if no nodes were found at the drop location.
