Purpose: stereo3D: two windows, draw same sphere in
both, then move it identically in both. ("Stereo" is
irrelevant to this apparent bug) :
scene1= #(standard 'display' setup)
scene2= #(same as above, different screen location)
ball1= #(define sphere standard way)
newxyz() #(a def:; creates, returns a random x,y,z)
#Put in a loop: (for or while)
BUG: Fails to draw in scene1.
Seems to *skip* it. Draws in scene2 only, correctly:
ball jumps around.
Moving the balls in two windows (two scenes) does not
work. I have NO idea why not. I have tried every
imaginable combination of draw commands.
#(Put in a loop like above)
ball= #(define shere standard way)
Draws balls in both windows, same places in both, but
does not delete/replace ("move") them.
IOW, drawing same item in two windows works;
*moving* a ball in two windows does not.
