Hi, I noticed calcVertexTangents uses Vec4f texcoords, rather than Vec3f. Further probing shows that it stores the sign of the cross-product computed when orthogonalizing the tangent space basis in the fourth vec.
My own TS-calc routines don't use that at all. I'm curious which cases it is good to have access to that info?
