Hi, I would like to know what is the Cull time in the osg stats (the blue bar) means.
I notice it changes together with draw time when I zoom in/out of my scene. I tried to disable the camera cull by setting NO_CULLING for the camera, but it didn't remove the cull time at all. It looks like the Cull time in the stats is some sort of culling which is done after the camera cull, probably is the CullVisitor. Is there a way to skip this culling process? I am trying to improve my app's performance at the moment. I know I can use DrawThreadPerContext instead of SingleThread. and also reuse my StateSet/StateAttribute to improve a bit. But both of them require major code change on my app. And most of time the whole scene should be rendered in my app anyway, so there is not much point to do culling, and if it can be disabled, I think it will increase my performance a lot. I also tried setCullingActive(false) to all the nodes in the scene, but it doesn't work. (it even increase the event time.) below is my stats under XP OSG 2.8.1, 2.83GHZ Duo CPU 2G Ram, ATI Radeon HD 2400XT . Cull: ~18 Draw: ~36 Stateset: 8100 Group:7320 Transform:1944 Geode:1974 Drawable:2815 Vertices:77303 Thank you!
