MDrawRequestQueue Class Reference

#include <MDrawRequestQueue.h>

Class Description

This method is obsolete.

Use MHWRender::MRenderItem and MHWRender::MPxGeometryOverride instead for Viewport 2.0 support.

This class defines a simple interface for a collection of MDrawRequest objects.

An MDrawRequestQueue object is passed to the getDrawRequests method of a user defined shape's UI class (MPxSurfaceShapeUI). This queue keeps track of all the things that need to get draw when a refresh of the view occurs.

Maya will call the getDrawRequest methods of all the visible DAG objects before a refresh happens. Then as the refresh happens, each draw request will be processed and the corresponding draw method for each DAG object will get called. For user defined shapes MPxSurfaceShapeUI::draw will get called.
