Hi M&M,
<< 3DS uses a Z-buffer, by which it knows how far away from the camera each
pixel of each object is.. >>
I believe that 3DS *provides* a Z-buffer to IPAS programmers but uses
an A-buffer internally. Because the Z-buffer operates in image
precision, it is subject to aliasing. The A-buffer addresses this
problem by using a discreet approximation to unweighted area
sampling.
