But I believe that there is a bug which prevents it from working when you use view-frustum culling. I'd have to double check that.The main reason that I wasn't sure is that the geometry classes include a shape reference. But they can only remember one. So what if you have 100 shapes sharing the same geometry?
Consider this as a bug. The reason for this is that currently the shape has a bounding volume which gets updated whenever the geometry changes. So the geometry triggers its shape to update the volume if needed. I will fix this ASAP.
