I have a model with many square shaped blocks (with huge depth complexity).
I have played around with occluder nodes to reduce my draw timings. They
are really good, but too many gives unacceptable cull timings.
I thought if I define some bounding boxes, that have some kind of
exclusion lists, I can increase the performance even more.
This is what I mean:
I place a bounding box along a road.
I add all nodes that are occluded by other geometry to a nodelist of the
bounding box node.
When the viewer is inside this bounding box, all the nodes in the
nodelist will be hidden.
Before I begin to implement this, I wonder if someone here has some tips
how to do this. Are there any existing suitable nodes in osg that could be
used as a starting point? Or does it already exist a node in osg that does
this?
