Ok I tried to use a drawable cull callback. It seems to work but there
are several behaviour that I don't understand.
Is it normal that no backface seems to be culled? Even if I'm in
CLUSTER_CULLING mode.
What if I derived from ClusterCullingCallback instead of Drawable::CullCallback?
Is it normal that the VIEW_FRUSTUM_SIDES_CULLING is not sharp, I mean
that nodes or drawables that are not in the field of view are not
culled immediately. They are eventually culled if I continue to move
the model far away from the field of view.
Yes, the are culling on their bounding volumes, this enclose the
subgraph, but typically aren't tightly bound due to the nature of
bounding sphere/boxes.
