If you are only interested in knowing whether something is inside or
outside the view volume, you could use a polytope intersector for that.
But if you need to know if it's culled because of, say, small feature
culling, or occlusion culling, than you'll need something more complex.
I don't think CullVisitor is your answer, as it does much more than
just cull. It computes LODs, sets up the render graph, etc. -Paul James Buckthorpe wrote: Hi, I am using CullCallback to work out whether a node has been culled or not. I'd like a way of doing this without rendering the scene if possible as it is part of a calculation routine for a visualization application. I was hoping that passing a CullVisitor to my root node might do the trick - something like:osgUtil::CullVisitor *cv = osgUtil::CullVisitor::create(); sceneNode->accept(*cv); but this gives me memory errors so clearly this isn't valid. Does anyone know the right way to go about this? I have tried looking in the example source code and on the forums but am still none the wiser. Any suggestions welcome.
