Function b3CreateMeshShape

) -> b3ShapeId

Create a mesh hull shape and attach it to a body. The shape definition is fully cloned but the mesh is not. Contacts are not created until the next time step. Mesh collision only creates contacts on static bodies. @warning this holds reference to the input mesh data which must remain valid for the lifetime of this shape @return the shape id for accessing the shape
