Box to Trimesh Collisions #396

Open ghost opened 6 years ago

ghost commented 6 years ago

How feasible is it that Box to TriMesh collision can be added to the library? It looks like it hasn't been developed for over 2 years so I'm guessing that it is unlikely. But it would be very useful. Sphere to TriMesh is a bit limiting.

Yes, I think it's unlikely. Apparently there were attempts at convex to Trimesh collisions, but it's all commented out.

From what I understand schteppe isn't entirely done with Cannon, but he's busy with other things at the moment.

Have you heard of Ammo.js? It definitely supports Box to Trimesh, as well as any other collision pair you can think of, but I did find it to be lacking in other areas.

Thanks for the advice.

Have you heard of Ammo.js https://github.com/kripken/ammo.js? It definitely has Box to Trimesh collisions, but I found it to be lacking in many other areas.
