Sounds like this may be a floating point precision issue in the Z-buffer and your aircraft is simply failing z-buffer test but passing the OSG culling test it might also be failing the cull test because of that
One way to check if is that type of issue is to place a cull callback on the aircraft node, if it gets called/visited then you know you passed the cull test and that's it's a zbuffer issue -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ümit uzun Sent: Tuesday, May 06, 2008 10:11 AM To: [email protected] Subject: [osg-users] Aircraft getting invisible by AutoCullingSystem Hi Robert, Firstly you are welcome to mail list :) I have an question about culling problem. I have an aircraft and earth model. Their size is "aircraft = 0e-07 " and "earth = 2e+07". When I add the aircraft node to the coordinateSystemNode which all nodes tied to it, aircraft get invisible. I think automatic culling system is culling the aircraft from the scene. I have try to add ; viewer.getCamera()->setComputeNearFarMode( osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR ); std::cout<<"NearFarMode : "<getComputeNearFarMode()<getCullingMode(); cullingMode &= ~ ( osg::CullStack::SMALL_FEATURE_CULLING ); viewer.getCamera()->setCullingMode( cullingMode ); then result is same. Why my little aircraft culling from scene? How can I fix this problem? Thanks so much...
