I have seen a similar effect when displaying rows of sphere primitives that
overlap, I wasnt sure why and didnt consider it a problem - I assumed it was
to do with the number of triangles making the spheres. IE: triangles that
partially covered each other when spheres overlapped where removed rather
than clipped to the right shape?
I assume from reading below this is the culling problem?
Is it possible to get J3D to clip intersecting tringles when shape3D's
intersect so they render with 'flush' edges rather than just removing the
triangle?
