QD3D 01 - Can't Turn Off DrawContext's clearImageMethod (1-June-95)
Q When we have the interactive renderer on, and we try to turn off the
DrawContext's clearImageMethod to kQ3ClearMethodNone, it still clears. This
works properly with the wire-frame renderer, but we need this feature in the
interactive renderer, as we are pasting in background pictures that we want to
act as a backdrop to our 3D models, and the interactive renderer always
obliterates the picture with the clearImageColor.
A This is a renderer-dependent feature that is supported by the wire-frame
renderer, but not the Interactive renderer. We intend to provide a "Clear with
picture" method in the next major release of QuickDraw 3D.
