Can be initialized to a custom-fit bounding volume, otherwise the SceneGraph will automatically calculate one.
Can be initialized to a custom-fit bounding volume, otherwise the SceneGraph will automatically calculate one. If specified by the user then the Scene Graph will not update the bounding when vertex data is modified. In this case the user is responsible for updating the bounding volume.
If the vertex geometry is not accessible (stored only in the GPU memory) then the bounding volume must be provided by the user.
