Description
Once you have created a rigid body in the world, you need to add one or more collision shapes to it so that it is able to collide with other bodies.
The collision shapes are also the way to represent the mass of a Rigid Body. Whenever you add a collision shape to a rigid body, you need to specify the mass of the shape. Then the rigid body will recompute its total mass, its center of mass and its inertia tensor taking into account all its collision shapes.
ConcaveMeshShape
The ConcaveMeshShape class can be used for a static concave triangular mesh.
It can be used to describe an environment for instance. Note that it cannot be used with a dynamic body that is allowed to move. Moreover, make sure to use a ConcaveMeshShape only when you are not able to use a convex shape and also try to limit the number of triangles of that mesh because collision detection with ConcaveMeshShape is quite expensive compared to convex shapes.
