Detailed Description

This is the base class for objects and modifiers.

Anything with a representation in the 3D viewports is derived from BaseObject (including modifiers and controllers whose gizmos appear in the viewports). The methods here are things such as displaying the object in the viewports, checking for intersection of the object and points the user clicks with the mouse, snapping to the object, and computing various bounding boxes for the object. Also there are methods for returning the name of the object to appear in the modifier stack, a method to deal with creating the object in the viewports (if appropriate), and named selection set related methods. There are also methods that allow other plug-ins to access the changeable parameters of the object. Finally there are several method that deal with sub-object selection, sub-object display, sub-object hit testing, and moving/rotating/scaling sub-object components of the object.

◆ SetExtendedDisplay()

virtual void SetExtendedDisplay ( int flags )

inlinevirtual

This method is used for storing mode-dependent display attributes.

Before an object's Display() method is called, the appropriate bits of the extended display flag variable are set and this method is called. After that, the Display() method is called. If the object must display itself differently based on the settings of the extended display bit fields, then the object must save the flags passed into the this method. Otherwise, there is no need for the object to store the flags.

Parameters

flags The flags to store.

Reimplemented in MSModifierXtnd, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, and MSObjectXtnd< GenLight, MSPluginLight >.

◆ Display() [1/2]

virtual int Display	(	TimeValue	t,
		INode *	inode,
		ViewExp *	vpt,
		int	flags
	)

inlinevirtual

This is called by the system to have the item display itself (perform a quick render in viewport, using the current TM).

Note: For this method to be called the object's validity interval must be invalid at the specified time t. If the interval is valid, the system may not call this method since it thinks the display is already valid.

Parameters

t	The time to display the object.
inode	The node to display.
vpt	An interface pointer that may be used to call methods associated with the viewports.
flags	See Display Flags.

Returns: Default return value is -1, means this object doesn't have display function. 0 means it didn't draw anything in current frame. Otherwise return positive values..

◆ GetWorldBoundBox() [1/2]

virtual void GetWorldBoundBox	(	TimeValue	t,
		INode *	inode,
		ViewExp *	vp,
		Box3 &	box
	)

inlinevirtual

This method returns the world space bounding box for Objects (see below for the Sub-object gizmo or Modifiers gizmo version).

The bounding box returned by this method does not need to be precise. It should however be calculated rapidly. The object can handle this by transforming the 8 points of its local bounding box into world space and take the minimums and maximums of the result. Although this isn't necessarily the tightest bounding box of the objects points in world space, it is close enough.

Parameters

t	The time to compute the bounding box.
inode	The node to calculate the bounding box for.
vp	An interface pointer that can be used to call methods associated with the viewports.
box	Contains the returned bounding box.

Reimplemented in DummyObject, SimplePolyObject, TriObject, SplineShape, SimpleSpline, SimpleShape, SimpleParticle, SimpleWSMObject, SimpleObjectBase, PolyObject, PatchObject, MSPluginSimpleMeshMod, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSSimpleObjectXtnd, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, MSPluginObject< GenLight >, SimpleManipulator, LinearShape, GizmoObject, MSCameraXtnd, MSLightXtnd, and MSHelperXtnd.

◆ GetLocalBoundBox()

virtual void GetLocalBoundBox	(	TimeValue	t,
		INode *	inode,
		ViewExp *	vp,
		Box3 &	box
	)

inlinevirtual

This is the object space bounding box, the box in the object's local coordinates.

The system expects that requesting the object space bounding box will be fast.

Parameters

t	The time to retrieve the bounding box.
inode	The node to calculate the bounding box for.
vp	An interface pointer that may be used to call methods associated with the viewports.
box	Contains the returned bounding box.

Reimplemented in DummyObject, SimpleSpline, SimpleShape, SimplePolyObject, TriObject, SplineShape, SimpleParticle, SimpleWSMObject, SimpleObjectBase, PolyObject, PatchObject, MSSimpleModXtnd, MSPluginSimpleMeshMod, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSSimpleObjectXtnd, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, MSPluginObject< GenLight >, SimpleManipulator, LinearShape, GizmoObject, MSCameraXtnd, MSLightXtnd, MSHelperXtnd, and Manipulator.

◆ GetCreateMouseCallBack()

virtual CreateMouseCallBack* GetCreateMouseCallBack ( )

pure virtual

This method allows the system to retrieve a callback object used in creating an object in the 3D viewports.

This method returns a pointer to an instance of a class derived from CreateMouseCallBack. This class has a method proc() which is where the programmer defines the user/mouse interaction during the object creation phase.

Returns: A pointer to an instance of a class derived from CreateMouseCallBack.

Implemented in SimpleSpline, SimpleShape, SimpleModBase, MSPluginSimpleSpline, TriObject, SplineShape, SimpleOSMToWSMObject, SimpleWSMMod, PolyObject, PatchObject, PFSimpleAction, MSSimpleModXtnd, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSPluginSimpleManipulator, MSSimpleObjectXtnd, MSPluginSimpleObject, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, MSPluginObject< GenLight >, LinearShape, BoxGizmoObject, CylGizmoObject, SphereGizmoObject, and DummyObject.

◆ GetObjectName() [1/2]

virtual const MCHAR* GetObjectName ( )

inlinevirtual

Note: This method has been deprecated in terms of implementation as of 3ds Max 2022. Plugin developers should implement GetObjectName(bool localized) const instead. This method can no longer be overriden and calls to it are now forwarded to the function that replaced it with a "bool localized" value of true. This is done so that plugin developers who do not localize their plugins don't have to update all the places where they call this method. Plugin developers who do localize their plugins should analyze the places where they call this method to decide what value to pass it for the "bool localized" parameter.

See also: BaseObject::GetObjectName(bool localized) const

     {
         return GetObjectName(true);
     }

◆ GetObjectName() [2/2]

virtual const MCHAR* GetObjectName ( bool localized ) const

inlinevirtual

Returns: the name that will appear in the modifier stack.

Parameters

localized If true, then the object name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the object name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the object name in English.

Reimplemented in TriObject, SplineShape, SimpleOSMToWSMMod2, SimpleOSMToWSMMod, PolyObject, PatchObject, MSSimpleModXtnd, MSPluginSimpleMod, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSPluginSimpleManipulator, MSPluginSimpleSpline, MSSimpleObjectXtnd, MSPluginSimpleObject, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, MSPluginObject< GenLight >, LinearShape, BoxGizmoObject, CylGizmoObject, SphereGizmoObject, DummyObject, and PFSimpleAction.

◆ OKToChangeTopology()

virtual CoreExport BOOL OKToChangeTopology ( MSTR & modName )

virtual

Implemented by the System.

This method is called to see if any modifiers down in the pipeline depend on topology. It sends the message REFMSG_IS_OK_TO_CHANGE_TOPOLOGY to see if any modifiers or objects down the pipeline depend on topology.

Parameters

modName This parameter is set to the dependent modifier's name if there is an item that depends on topology.

Returns: TRUE if it is okay to change the topology; FALSE if it is not okay to change the topology.

Reimplemented in PFSimpleAction.

◆ ChangeTopology()

virtual BOOL ChangeTopology ( )

inlinevirtual

This method asks the question of an object or modifier "Do you change topology"? An object or modifier returns TRUE if it is capable of changing topology when its parameters are being edited; otherwise FALSE.

When an item is selected for editing, and there is a modifier in the pipeline that depends on topology, the system calls this method to see if it may potentially change the topology. If this method returns TRUE the system will put up a warning message indicating that a modifier exists in the stack that depends on topology.

◆ GetParamBlockIndex()

virtual int GetParamBlockIndex ( int id )

inlinevirtual

If a plug-in makes its parameter block available (using GetParamBlock()) then it will need to provide #defines for indices into the parameter block.

These defines should not be directly used with the parameter block but instead converted by this function that the plug-in implements. This way if a parameter moves around in a future version of the plug-in the #define can be remapped. A return value of -1 indicates an invalid parameter id.

Parameters

id	The parameter block id. See Parameter Block IDs.

Returns: The parameter block index or -1 if it is invalid.

Reimplemented in SimpleObject, SimpleMod, SimpleSpline, SimpleShape, SimpleParticle, SimpleWSMObject, and SimpleWSMMod.

◆ Move()

virtual void Move	(	TimeValue	t,
		Matrix3 &	partm,
		Matrix3 &	tmAxis,
		Point3 &	val,
		BOOL	localOrigin = `FALSE`
	)

inlinevirtual

When this method is called the plug-in should respond by moving its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	This value is a vector with X, Y, and Z representing the movement along each axis.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin.

◆ Rotate()

virtual void Rotate	(	TimeValue	t,
		Matrix3 &	partm,
		Matrix3 &	tmAxis,
		Quat &	val,
		BOOL	localOrigin = `FALSE`
	)

inlinevirtual

When this method is called the plug-in should respond by rotating its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	The amount to rotate the selected components.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin. Note: This information may be passed onto a transform controller (if there is one) so they may avoid generating 0 valued position keys for rotation and scales. For example if the user is rotating an item about anything other than its local origin then it will have to translate in addition to rotating to achieve the result. If a user creates an object, turns on the animate button, and rotates the object about the world origin, and then plays back the animation, the object does not do what the was done interactively. The object ends up in the same position, but it does so by both moving and rotating. Therefore both a position and a rotation key are created. If the user performs a rotation about the local origin however there is no need to create a position key since the object didn't move (it only rotated). So a transform controller can use this information to avoid generating 0 valued position keys for rotation and scales.

◆ Scale()

virtual void Scale	(	TimeValue	t,

inlinevirtual

When this method is called the plug-in should respond by scaling its selected sub-object components.

Parameters

t	The time of the transformation.
partm	The 'parent' transformation matrix. This matrix represents a transformation that would take points in the modifier's space and convert them into world space points. This is constructed as the node's transformation matrix times the inverse of the ModContext's transformation matrix. The node whose transformation is used is the node the user clicked on in the scene - modifiers can be instanced so there could be more than one node.
tmAxis	The matrix that represents the axis system. This is the space in which the transformation is taking place.
val	This value is a vector with X, Y, and Z representing the scale along X, Y, and Z respectively.
localOrigin	When TRUE the transformation is occurring about the sub-object's local origin. See the note above in the Rotate method. The following methods may be used to receive notification about the starting and ending phases of transforming the item when in sub-object selection.

◆ CloneSelSubComponents()

virtual void CloneSelSubComponents ( TimeValue t )

inlinevirtual

This method is called to make a copy of the selected sub-object components of the item.

If this is called on an object, the selection level of the object is used to determine which type of sub-objects are cloned. For instance in a Mesh, the selection level determines if selected verticies, edges or faces are cloned. If this is called on a Modifier then the selection level of the modifier is used.

◆ SubObjectIndex()

virtual int SubObjectIndex ( HitRecord * hitRec )

inlinevirtual

Returns the index of the sub-object element identified by the HitRecord hitRec.

See Class HitRecord. The sub-object index identifies a sub-object component. The relationship between the index and the component is established by the modifier. For example an edit modifier may allow the user to select a group of faces and these groups of faces may be identified as group 0, group 1, group 2, etc. Given a hit record that identifies a face, the edit modifier's implementation of this method would return the group index that the face belonged to.

◆ ActivateSubobjSel()

virtual void ActivateSubobjSel	(	int	level,
		XFormModes &	modes
	)

inlinevirtual

When the user changes the selection of the sub-object drop down, this method is called to notify the plug-in.

This method should provide instances of a class derived from CommandMode to support move, rotate, non-uniform scale, uniform scale, and squash modes. These modes replace their object mode counterparts however the user still uses the move/rotate/scale tool buttons in the toolbar to activate them. If a certain level of sub-object selection does not support one or more of the modes NULL may be passed. If NULL is specified the corresponding toolbar button will be grayed out.

Parameters

level	The sub-object selection level the command modes should be set to support. A level of 0 indicates object level selection. If level is greater than or equal to 1 the index refers to the types registered by the object in the order they appeared in the list when registered by Interface::RegisterSubObjectTypes(). See Class Interface.

◆ NewSetByOperator()

virtual void NewSetByOperator	(	MSTR &	newName,
		Tab< int > &	sets,
		int	op
	)

inlinevirtual

To support the Edit Named Selections dialog, plug-ins must implement this method.

The user may bring up the Edit Named Selections dialog via the Edit / Edit Named Selection ... command. This dialog allows the user to create new selection sets using 'boolean' operations to the sets including 'Combine', 'Subtract (A-B)', 'Subtract (B-A)' and 'Intersection'. This method is called on the plug-in to generate a new selection set via one of these operations. This method assumes the developer will append a new seleciton set with the name passed. This will result in two sets with identical names. Then the system will call RemoveSubSelSet() afterwards, so that the first one that is found (the old one, since the new one was appended) will be deleted. Note: Developers need to implement Undo / Redo for modifications to their named selection sets. See /MAXSDK/SAMPLES/MODIFIERS/MESHSEL.CPP for an example.

Parameters

newName	The new name for the selection set is passed here.
sets	A table of the selection sets to operate on. There are sets.Count() sets in the table.
op	One of the following values defined in Arguments for BaseObject::NewSetByOperator()

◆ NumSubObjTypes()

virtual int NumSubObjTypes ( )

inlinevirtual

Objects and modifiers that support subobjects have to overwrite this method - as well as GetSubObjType() - and return a class derived from ISubObjType in GetSubObjType().

Developers can use the GenSubObjType for convenience. If the parameter passed into GetSubObjType is -1, the system requests a ISubObjType, for the current SubObjectLevel that flows up the modifier stack. If the subobject selection of the modifier or base object does not affect the subobj selection that flows up the stack, the method must return NULL. See meshsel.cpp for a sample implementation.

Returns: The number of sub-object types supported by the object or modifier.

Reimplemented in SimpleModBase, SplineShape, and PatchObject.

1099 { return 0;}

◆ GetSubObjType()

virtual ISubObjType* GetSubObjType ( int i )

inlinevirtual

Returns a pointer to the sub-object type for the sub-object whose index is passed.

If the parameter i passed is -1 the system requests an ISubObjType for the current SubObjectLevel that flows up the modifier stack. If the subobject selection of the modifier or base object does not affect the sub-object selection that flows up the stack NULL must be returned. See the sample code in /MAXSDK/SAMPLES/MODIFIERS/MESHSEL.CPP.

Parameters

i	The zero based index of the sub-object type to get. See the remarks above.

Returns: The sub-object type. See Class ISubObjType.

Reimplemented in SimpleModBase, SplineShape, and PatchObject.

1110 { return NULL; }

◆ GetSubObjectLevel()

virtual CoreExport int GetSubObjectLevel ( )

virtual

This method returns an integer which indicates the current sub-object level of the modifier or base object.

Returns: A value of 0 indicates object level. A value of 1 through NumSubObjTypes() are the sub-object levels in the same order as they are returned by GetSubObjType(int i) (with an offset of 1 of course).

Reimplemented in PatchObject.

◆ HasUVW() [1/2]

virtual BOOL HasUVW ( )

inlinevirtual

Call this method to find out if the object has UVW coordinates.

This method returns TRUE if the object has UVW coordinates; otherwise FALSE. In 3ds Max 2.0 and later there is code in the renderer that will automatically turn on the UVW coordinates of the base object if UV's are missing (and needed). The base object has to implement two simple methods to make this work: HasUVW() and SetGenUVW(). Developers are encouraged to put these methods in their objects: it makes using the program easier for the user. If they are not implemented, it doesn't cause any real harm: it will just operate as before and put up the missing UVW's message. Here is how the procedural sphere implements these methods:

BOOL SphereObject::GetGenUVW()
{
    BOOL genUVs;
    Interval v;
    pblock->GetValue(PB_GENUVS, 0, genUVs, v);
    return genUVs;
}
 
void SphereObject::SetGenUVW(BOOL sw)
{
    if (sw==GetGenUVW()) return;
    pblock->SetValue(PB_GENUVS,0, sw);
}

Important Note: The pblock->SetValue() will cause a call to NotifyDependents(FOREVER, PART_TEXMAP, REFMSG_CHANGE), which will invalidate the UVW cache. It is essential that this call be made, so if the 'generate UVW' boolean is not handled by a parameter block, then NotifyDependents() needs to be called explicitly. Also Note: For "modifiable objects" that pass up the pipeline getting modified, such as TriObject, EditTriObject, etc., which cannot generate their own UVWs, but can carry them in their data structures, only this HasUVW() method needs to be implemented. For example, here is the implementation for TriObject: BOOL TriObject::HasUVW() { return mesh.tvFace?1:0; }

Reimplemented in MSPluginSimpleSpline, TriObject, PolyObject, ShapeObject, Object, MSSimpleModXtnd, MSPluginSimpleMeshMod, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSSimpleObjectXtnd, MSPluginSimpleObject, MSShapeXtnd, MSPluginShape, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, and MSPluginObject< GenLight >.

◆ HasUVW() [2/2]

virtual BOOL HasUVW ( int mapChannel )

inlinevirtual

Call this method to find out if the object is has UVW coordinates for the specified mapping channel.

This method returns TRUE if the object has UVW coordinates; otherwise FALSE. See the method HasUVW() above for more details.

Parameters

mapChannel See Mapping Channels.

Reimplemented in TriObject, PolyObject, ShapeObject, Object, and MSModifierXtnd.

1166 { return (mapChannel==1) ? HasUVW() : FALSE; }

BaseObject::HasUVW

virtual BOOL HasUVW()

Call this method to find out if the object has UVW coordinates.

Definition: object.h:1160

◆ SetGenUVW() [1/2]

virtual void SetGenUVW ( BOOL sw )

inlinevirtual

This method is called to change the state of its Generate UVW boolean.

If the state changes, the object must send a REFMSG_CHANGE up the pipeline by calling NotifyDependents(). This applies to map channel 1.

Parameters

sw	The new state for the generate UVW flag.

Reimplemented in MSPluginSimpleSpline, ShapeObject, MSSimpleModXtnd, MSPluginSimpleMeshMod, MSModifierXtnd, MSPluginModifier, MSSimpleManipulatorXtnd, MSSimpleObjectXtnd, MSPluginSimpleObject, MSShapeXtnd, MSPluginShape, MSObjectXtnd< GenCamera, MSPluginCamera >, MSObjectXtnd< HelperObject, MSPluginHelper >, MSObjectXtnd< ShapeObject, MSPluginShape >, MSObjectXtnd< GeomObject, MSPluginGeomObject >, MSObjectXtnd< GenLight, MSPluginLight >, MSPluginObject< ShapeObject >, MSPluginObject< HelperObject >, MSPluginObject< GeomObject >, MSPluginObject< GenCamera >, and MSPluginObject< GenLight >.

◆ SetGenUVW() [2/2]

virtual void SetGenUVW	(	int	mapChannel,
		BOOL	sw
	)

inlinevirtual

This method is called to change the state of its Generate UVW boolean for the specified mapping channel.

If the state changes, the object must send a REFMSG_CHANGE up the pipeline by calling NotifyDependents().

Parameters

mapChannel	The mapping channel index. See Mapping Channels.
sw	The new state for the generate UVW flag.

Reimplemented in ShapeObject, and MSModifierXtnd.

1178 { if (mapChannel==1) SetGenUVW (sw); }

BaseObject::SetGenUVW

virtual void SetGenUVW(BOOL sw)

This method is called to change the state of its Generate UVW boolean.

Definition: object.h:1171

◆ ShowEndResultChanged()

virtual void ShowEndResultChanged ( BOOL showEndResult )

inlinevirtual

This method notifies the BaseObject that the end result display has been switched (the "Show End Result" button has been toggled).

Sometimes this is needed for display changes. This method is implemented in Edit Mesh, which uses it as shown below: void EditMeshMod::ShowEndResultChanged(BOOL showEndResult) {

NotifyDependents(FOREVER, PART_DISPLAY, REFMSG_CHANGE);

}

This allows the Edit Mesh modifier to update itself in repsonse to a user click of the "Show End Result" button in the modifier panel.

Parameters

showEndResult TRUE if Show End Result is on; FALSE if off.

Reimplemented in SplineShape, PatchObject, and MSModifierXtnd.

1190 { }

◆ HasViewDependentBoundingBox()

virtual BOOL HasViewDependentBoundingBox ( )

inlinevirtual

This method return true if GetWorldBoundBox returns different boxes for different viewports.

It is used to inhibit a caching of the bounding box for all viewports. This was added to allow developers to disable the bounding box cache. It may be overridden to return true if an object has a dynamic drawing style, or as the method suggests is view dependent.

Returns: true if the bounding box should not be cached for use on all viewports, false otherwise.

1199 { return false; }
