Detailed Description

This method is obsolete.

Deprecated:: Use MHWRender::MRenderOverride instead.

MPx3dModelView is the class for user defined model views. The MPx3dModelView class works with the MPxModelEditorCommand class to create a user defined model editor that may be used in a window or in a scripted panel. When registering the model editor with the MFnPlugin::registerModelEditorCommand() method, an appropriate MPx3dModelView::creator() method is required. This class works for interactive Maya views and is not designed for rendering.

One of the interesting uses of a MPx3dModelView is that it allows multiple cameras to be drawn into the same window. Like a normal model view, this view has a main camera associated with it. This camera is obtained with the getCamera() method and is the camera used for manipulations and selection.

To setup a multiple camera draw, first the number of passes must be set by an overloaded multipleDrawPassCount() method. The preMultipleDraw() method allows any setup to be performed. The preMultipleDrawPass(unsigned int) is called for each pass, with the argument indicating which pass is currently being used. The camera for the specific pass may be set with the setCameraInDraw() method. The postMultipleDrawPass(unsigned int) method is called after the drawing for the indicated pass is complete. Finally any cleanup may be done with the postMultipleDraw() method.

During the drawing, a filter exists to determine which items should be drawn. The okForMultipleDraw(MdagPath &) allows filtering of what should be drawn. Another approach which is faster is to tuen on the view selected mode (setViewSelected()) and use the setObjectsToView() or viewSelectedSet() to specify which items should be drawn. These values may be set per pass so that each camera has control over what gets drawn.

Examples:: exampleCameraSetView/exampleCameraSetView.h, exampleCameraSetView/exampleCameraSetViewCmd.cpp, exampleCameraSetView/exampleCameraSetViewCmd.h, narrowPolyViewer/narrowPolyViewer.cpp, narrowPolyViewer/narrowPolyViewer.h, and narrowPolyViewer/narrowPolyViewerCmd.cpp.

Parameters

[out] ReturnStatus status

Returns: The name of the view.

Status Codes:

MS::kSuccess Operation successful

MString viewType ( ) const

virtual

Returns a string specifying the view type.

The view type should be a different string for every class derived from MPx3dModelView. The default type is "MPx3dModelView".

Returns: The view type

Examples:: exampleCameraSetView/exampleCameraSetView.h, narrowPolyViewer/narrowPolyViewer.h, and narrowPolyViewer/narrowPolyViewerCmd.cpp.

void preMultipleDraw ( )

virtual

This method is called before any drawing is performed in the model view.

It should control any setting required for every pass that will be drawn.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

void postMultipleDraw ( )

virtual

This method is called after the drawing is finished.

Any cleanup should be done by this method.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

void preMultipleDrawPass ( unsigned int index )

virtual

This method is called immediately before a specific pass is about to be drawn.

The unsigned int argument indictates which pass is about to be drawn.

Typically the camera (set with the setCameraInDraw method) and any pass specific settings would be made here.

Parameters

[in] index A number indicating which pass is about to be drawn.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

void postMultipleDrawPass ( unsigned int index )

virtual

This method is called when a specified pass is finshed.

Parameters

[in] index A number indicating which pass was just drawn.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

bool okForMultipleDraw ( const MDagPath & dp )

virtual

This method provides some filter capabilities as to what is drawn.

When ever a draw operation during the multiple camera drawing, this method will get called. If true is returned, then the object will be drawn.

This method is useful for filtering out multiple occurances of manipulators and ground planes.

To reduce the number of objects queried, look at the setViewSelected() method along with the setObjectsToView() method.

Parameters

[in] dp A MDagPath of the object that may be drawn.

Returns: true if it is OK to draw the passed object.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

unsigned int multipleDrawPassCount ( )

virtual

This method returns the number of multiple draw passes that are going to be made.

By default a 1 is returned.

Returns: The number of multiple draw passes that will be made.

Status Codes:

MS::kSuccess Operation successful

Examples:: narrowPolyViewer/narrowPolyViewer.h.

bool multipleDrawEnabled ( ) const

This method returns the multiple draw enable state for this view.

Returns: true if multiple draw is enabled.

void setMultipleDrawEnable ( bool enable )

This method turns enables/disables multiple camera drawing for this view.

If multiple draw is disabled, then this view will behave like a normal Maya view.

Parameters

[in] enable If true, then multiple draw is enabled.

bool destroyOnPanelDestruction ( ) const

This method queries the destruction setting for this MPx3dModelView which is employed when the panel associated with this view is destroyed.

By choosing to have the MPx3dModelView destroyed along with the panel, you are guaranteed that a new MPx3dModelView will be created the next time the editor is displayed.

Returns: true if this MPx3dModelView gets destroyed when its panel is destroyed (such as closing a torn-off window), and false if it is not to be destroyed.

void setDestroyOnPanelDestruction ( bool how )

This method enables/disables destruction of the MPx3dModelView object when the panel is destroyed.

By default, Maya does not destroy the MPx3dModelView when the panel is destroyed. Example cases of destroying a panel are when you tear off a panel, or close a torn-off panel.

By choosing to have the MPx3dModelView destroyed along with the panel, you are guaranteed that a new MPx3dModelView will be created the next time the editor is displayed.

Parameters

[in] how If true, destroy the MPx3dModelView when the panel is destroyed. If false (the default behaviour), the editor is retained.

MStatus updateViewingParameters ( )

This method tells the camera to set the view's transformation matrix.

Returns: Status code

void removingCamera ( MDagPath & cameraPath )

virtual

This method should be overloaded in MPx3dModelView derived classes.

It will get called whenever a camera that was used with this MPx3dModelView is deleted. The MPx3dModelView should then remove any reference to the deleted camera.

Parameters

[in] cameraPath The MDagPath for the camera that is about to be deleted.

Examples:: narrowPolyViewer/narrowPolyViewer.h.

MStatus setDoUpdateOnMove ( bool value )

Some viewports require a refresh when the user has moved the top level window.

This flag enables this custom view to trigger a refresh event when the top level window of the view is moved to a new location.

The default value for this flag is false.

Parameters

[in] value The state of the doUpdateOnMove flag.

Returns

Status code

Status Codes:

MS::kSuccess Method was successful
MS::kFailure Object error

bool doUpdateOnMove ( MStatus * ReturnStatus = NULL ) const

Returns the state of the doUpdateOnMove flag.

This flag tells the refresh architecture if it is necessary to refresh your view when the user moves the control window for this viewport. If this flag is true, then refresh will be triggered on window move.

Parameters

[in] ReturnStatus return status of the check

Returns

the state of the doUpdateOnMove flag

Status Codes:

MS::kSuccess Method was successful
MS::kFailure Object error

MStatus refresh	(	bool	all = `false`,
		bool	force = `false`
	)

Refresh the this view.

If all is set to true then all of the 3d-view will be refreshed.

If force is set to true, then the views will be refreshed even if they do not require it. This option should be used with extreme care because extra refreshes will greatly degrade application performance. In almost all cases it is better to use the default behavior where the view is only refreshed if it is required.

Parameters

[in]	all	If true then refresh all views, otherwise refresh this view.
[in]	force	If true then force views to refresh even if they do not require it.

Returns: Status code

This should only be called when setDrawAdornments has been set to false. And this method should only be called in the postMultiple* draw methods. This allows the drawing of display elements during a specific pass while attached to a specific camera.

Returns

MS::kFailure - invalid editor.
MS::kSuccess - success.

MStatus setDrawAdornments ( bool display )

Toggles the control of how adornments are drawn in the view.

Adornments are objects that are drawn in the viewport that are not scene entities. This includes the origin axis and the camera decorations like film gate and resolution gate. These items are usually drawn last and outside of the multiple refresh loop. You can choose to disable the drawing of the adornments by specifying false here, and you can control the drawing of the feature within their display loop calling displayAdornmentsNow() method on this class. By default this flag is true; so adornments are always drawn unless explicitly disabled by you.

Parameters

[in] display toggle to control the display of the adornments.

Returns: Status code

Status Codes:

MS::kSuccess Operation successful

bool drawAdornments ( MStatus * ReturnStatus = NULL )

Returns the state of the adornment drawing for this view.

MStatus beginXorDrawing	(	bool	drawOrthographic = `true`,

		M3dView::LineStipplePattern	stipplePattern = `M3dView::kStippleNone`,
		const MColor &	lineColor = `MColor(1, 1, 1)`
	)

Setup the context for exclusive-or (XOR) drawing.

In XOR drawing the color values of the pixels being drawn is exclusive-ored with the color values already present in the view. The advantage of this is that exclusive-oring the same pixels with the same color values a second time will restore the pixels to their original colors, making it possible to temporarily display and erase lines without having to redraw the entire view. This makes XOR drawing particularly useful for drawing guidelines for tools.

One disadvantage of XOR drawing is that the final color after the exclusive-or will not match your drawing color, except when the original color of the pixel was black. For example, XORing a white line across a red background will result in a cyan line and XORing it across a changing background will result in a line of changing colors. However in most situations where you would use XOR drawing the color of the lines is irrelevant just so long as they are visible.

It is an error to call beginXorDrawing() again before calling endXorDrawing() first.

Parameters

[in]	drawOrthographic	Draw using orthographic projection. Default is true.
[in]	disableDepthTesting	Disable depth testing during draw. Default is true.
[in]	lineWidth	Set up line width. Default is 1.
[in]	stipplePattern	Line stipple pattern. Default is M3dView::kStippleNone.

Returns: Status code

Status Codes:

MS::kSuccess Method was successful
MS::kFailure Object error

MStatus endXorDrawing ( )

If endXorDrawing() is called without first calling beginXorDrawing() an error will result.

Returns: Status code

Status Codes:

MS::kSuccess Method was successful
MS::kFailure Object error

MStatus setDrawColor	(	unsigned int	index,

The index argument is an index into the application's color tables. Valid values range between zero and the size of the table minus one. The size of the active and dormant color tables can be found using methods of this class. The background and template color tables are both of size one.

These indices do not directly correspond to those of the underlying OpenGL color index mode. Using the glIndex call directly is not recommended and may cause unpredictable results. This method should be used instead.

Note that this method will work in either RGBA mode or color index mode.

Parameters

[in]	index	index of the color to draw in
