Re: appHACDDemo (and Convex Decomposition tool)

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

Re: btBvhTriangleMeshShape questions

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...

Re: Vehicle wheels bouncing (not btRaycastVehicle)

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...

Re: About anisotropic friction coordinate system

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

Re: About anisotropic friction coordinate system

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...

About anisotropic friction coordinate system

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...
