I've added a _geometry->dirtyBound() to be called each visit but that didn't help.
I printed out the bounding sphere data and as it does change slightly it looks correct even when the square sections of the point cloud disappear and reappear. Any other ideas? Could this have something to do with the terrain being visible? This only seems to happen if the terrain is visible to the camera via its NodeMask. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian R Hill Sent: Thursday, April 24, 2008 1:02 PM To: OpenSceneGraph Users Subject: Re: [osg-users] Point cloud culling/paging Steve, Verify that your bounding sphere is what you think it should be. Print out the point cloud's bounding sphere every frame and check that it's correct. osg::BoundingSphere bs = pointcloud->getBound(): std::cout << "Ctr " << bs.center() << " rad " << bs.radius() << "\n"; Brian [EMAIL PROTECTED] wrote: ----- To: "OpenSceneGraph Users" <osg-users@lists.openscenegraph.org> From: "Steven Powers" <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] Date: 04/24/2008 11:11AM Subject: [osg-users] Point cloud culling/paging I'm experiencing some weird problems with my point cloud. I have a fairly large terrain and a point cloud that expands the whole terrain. When I build the point cloud and look around the environment whole sections of the point cloud disappear when they aren't centered within the camera's view. They will then reappear when the center of the missing section is within view. The point cloud is a POINTS primitive set and I have turned culling off ( setCullingActive (false)) as well as display lists. I've noticed that if I do not add the terrain model to the scene it works ok. What culling/paging option do I need to set to make sure this doesn't happen? -Steve _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g----------------------------------------------------------------------- ------------------------------------------------------------------------ --------------------------------- This is a PRIVATE message.
