Hi there,

I have to create complex geometries for a web application using java3d and I would like to know whether degenerate QuadArrays, i.e. QuadArrays that actually are triangles, cause any problems.
For example, if I want to model a sphere with QuadArrays, then at the poles of the sphere there will always be two vertices in a QuadArray which are identical, i.e. the QuadArrays form triangles.

Does that cause any problems within the java3d library?
I'd like to avoid splitting up the geometry into a QuadArray and a TriangleArray. Using my web application's existing framework it would be far easier to model everything using QuadArrays, as long as that doesn't break java3d.

Any thoughts on that?

Thanks in advance,
Schorsch
