btBvhTriangleMeshShape construction speed...

Post by reltham »

Is there a way to make btBvhTriangleMeshShapes to build faster? I have code loading up was meshes and building btBvhTriangleMeshShapes and it's taking quite a long time (on the order of minutes) for around 5000 total objects.

You should be able to (de) serialize pre-constructed btBvhTriangleMeshShapes, completely eliminating build times.

See #define SERIALIZE_TO_DISK in Demos/ConcaveDemo/ConcavePhysicsDemo.cpp

Hope this helps,
