View Objects Routines

Getting a View's Transforms

QuickDraw 3D provides routines that you can use to get matrix representations of the transforms associated with a view.

IMPORTANT

You should call these routines only between calls to Q3View_StartRendering and Q3View_EndRendering (or similar submitting loops). If you call them at any other time, they return kQ3Failure.
