Convex FALSE faces

[vralexllobet]

I have a question about creating faces with many angles either as convex or concave.
Recently I tested fps timings on a huge number of boxes with faces that were all convex or all concave with the same final face and noticed no difference in fps.

Is there a disadvantage to making a face with many angles, some >180 degrees internally, as one big face as opposed to making the face from smaller, all convex TRUE, faces?

Convex faces are faces where all interior angles are ≤ 180°, concave faces are faces where some initerior angles are > 180°. Because all faces with more than 3 vertices are triangulated, it should make no difference in performance if you set convex to TRUE or to FALSE. If you have only triangles you can also use IndexedTriangleSet or TriangleSet, which are optimised for this case.

But if you really have concave faces you will see a visual difference:

To set convex to FALSE is a hint to the browser to use a more complex triangulation technique. Rendering performance should be equal to a convex TRUE geometry but the build time of this geometry is probably a bit slower.
