Even Number of Triangles for Any 3D model - unknown - Sep 21, 2005 06:26 AM
Is it impossible for a 3D model to have an odd number of triangles? Assuming its got every edge has two triangles. Even Number of Triangles for Any 3D model - Zekaric - Sep 21, 2005 08:34 AM
If the surface is properly formed, no (I think); but if it has degenerate triangles, meaning two or more of a triangle's points are coincident, then all bets are off. I'm still trying to think of a case where it may fail but I'm not finding it. |
