Does the Bullet library support (continuous) swept-sphere collision detection against concave meshes? The demo only shows continuous convex detection. Is continuous concave possible?
Thanks in advance

Sorry for the large delay.
Bullet can do continuous collision detection between sphere versus 3d polysoup (terrain), by creating a 'temporal AABB', and then doing CCD between sphere versus each triangle that overlaps with this temporal AABB. This temporal AABB encloses the full motion (begin, in-between and end position) of the sphere.
This feature used to be working, but the CCD feature hasn't been activated in recent releases. When I get back to enabling CCD response (using time of impact), I'll doublecheck this is working properly.
Thanks for the feedback,
Erwin
