I'm rendering an animation with multiple triangle meshes.
In one frame of the animation all the triangles in one of the meshes 
degenerate and I get an error.  I've worked around it by including a 
"dummy" triangle hidden behind an opaque surface, but I was wondering if 
there's a more natural fix?
Thanks,
John

Just the obvious: don't create a mesh without any valid triangles. Check 
for the conditions that cause the degenerate mesh, and just don't 
specify it when they occur.
