Recently, my application has produced a problem with the drawing
order of various objects (I feel that the Z-buffering mechanism may be
the culprit). Essentially, when i change the scene graph by adding new
objects, the latest additions always appear on "top", regardless of
distance from the viewpoint or viewpoint position. This problem
developed only recently, so I restored an old working version, and the
problem has cropped up there, too. Although I do use a pair of GL calls to
turn on/off Zbuffering to draw 2D screen text, they do not seem to be the
source of my troubles. Are there any scene graph modifications/Performer
(1.2) calls that I could use to insure that the Z-buffering mechanism is
working properly? Thanks ...
Andy
