In this paragraph,
"Culling: The hierarchy that you make should be spatially
organized in a way that the culling process can quickly and
efficiently decide what to draw. The culling test in Performer
takes place at the geoset level and thus your MultiGen
database should use groups as your culling nodes. I have
found that an oct-tree is better than a quad tree since it will
<---------------?
make a shallower hierarchy. If you make too deep of a
hierarchy you will be spending all of your time culling and little
time drawing. This is a balance act between culling and
drawing.
Can anyone describe the terms "oct-tree,quad-tree?"
How can or does it effect my hierarchy when I'm using externally
referenced models? instanced? LODs?
thank you all......
