The DisplayPipeline type exposes the following members.
Calculate a bounding to include in the Zoom Extents command.
Called after all non-highlighted objects have been drawn and PostDrawObjects has been called. Depth writing and testing are turned OFF. If you want to draw with depth writing/testing, see PostDrawObjects.
If Rhino is in a feedback mode, the draw overlay call allows for temporary geometry to be drawn on top of everything in the scene. This is similar to the dynamic draw routine that occurs with custom get point.
Called after all non-highlighted objects have been drawn. Depth writing and testing are still turned on. If you want to draw without depth writing/testing, see DrawForeground.
Called right before an individual object is being drawn. NOTE: Do not use this event unless you absolutely need to. It is called for every object in the document and can slow disply down if a large number of objects exist in the document
Called before objects are been drawn. Depth writing and testing are on.
