[osg-users] Culling time is extremely long
Hi, I use compositeViewer, (osg 2.8.1) and each view contains no more than small amount of vertices. However the culling time, showed by the Statshelper, can be more than 30. The tricky thing is it is inconsistent between runs. Sometimes the culling time is 5 ~ 6. Then after I rerun the program, it shoots up to more than 30 I have attached the file for initializing views, Looking for help. Thank you!

Re: [osg-users] Culling time is extremely long
1) Are you running on Linux or Windows? 2) Are you running OSG debug or release optimized? 3) Are you running with the default cull settings? If you want helpful feedback, providing more info will provoke a better response from the community. I just see a screenshot of your stats. I don't see any file with initializing code... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Suyang Dong Sent: Saturday, February 25, 2012 4:07 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Culling time is extremely long Hi, I use compositeViewer, (osg 2.8.1) and each view contains no more than small amount of vertices.

Re: [osg-users] Culling time is extremely long
Hi Culling time is more about amount of nodes\drawables in scene and how they organized into graph, and less about vertices itself. You can try to run your model through osg optimizer with SPATIALIZE_GROUPS option. Also check if you use any cull callbacks with heavy running time. And if you have some nodes on which culling is disabled ( setCullingActive(false) ) deeply in graph structure, this can kill your performance too.
