Good job Flix, this will surely come handy. Decomposing concave meshes for collision shapes is always tedious

Maybe i am wrong but i think generic triangle meshes such as the btBvhTriangleMeshShape can only be used with static bodies (rigid bodies with a mass of 0). So you can not collide 2 object of this type together. For your dynamic bodies, always use simple collision shapes like spheres, boxes and so o...

this looks like a case of internal edge collision. Are you using a btBvhTriangleMeshShape for the terrain? if you are using btHeightfieldTerrainShape, change it for a btBvhTriangleMeshShape and look into the InternalEdgeDemo source code for details on how to use the internal edge utility to adjust t...

Well, anisotropic friction works great. It is in object coordinates and works in conjunction with the setFriction().

Good points Flix and thank you for the reply. Not to really answer your questions as i have the same ones but 1. I havent't found any demo or place explicitly using the setAnisotropicFriciton() or the m_anisotropicFriction directly. 2. I do suppose that it works out of the box as i can set setAnisot...

Hello, I have been experimenting with bullet for a while now and i really love it. So congrats to Erwin and other contributors for this great library. I would like to know if the btCollisionObject's anisotropic friction setting has to be applied in local object space or transformed world space? Is i...
