Normalizing a zero vector in btConnectivityProcessor

[cj3j]

I have a triangle mesh that's resulting in a zero vector being normalized in btConnectivityProcessor::processTriangle() It's the 'edge' vector:

Code: Select all

btVector3 edge(m_triangleVerticesA[sharedVertsA[1]]-m_triangleVerticesA[sharedVertsA[0]]);

I can't see anything obviously wrong with the mesh upon visual inspection. Any idea what would cause this? Is it okay to just exit out of the function when this situation occurs?

Nevermind? I had my m_equalVertexThreshold set too high.
