Changes in rayTest from v2.81 to v2.82

[Spaddlewit]

My program was using v2.81, and I recently upgraded to v2.82. My rayTest calls are producing some very wacky behavior. What was changed with the rayTest between v2.81 and v2.82?

Specifically, I'm performing a ray test against a btBvhTriangleMesh.

There is an issue with one of the ray cast functions, we need to fix it.

In the meanwhile, enable this flag for the old behavior:

Code: Select all

resultCallback.m_flags |= btTriangleRaycastCallback::kF_UseSubSimplexConvexCastRaytest;

I filed it in the new issue tracker at github, will be fixed for next release:
