Hi Zach, and thank you for the reply, I'me quite sure the nodes have culling active, since on the model is culled on the sides of the frustum, and on bottom and top of the frustrum. it just don't cull at the near and far.
my model has cullingActive TRUE on the ".osg" file. This is really wierd. I'm setting the perspective matrix on the right place?, if not where should I do it? , also, when I set the perspective, osg automatcly set the frustum polytope right? thank you Ryven ------------------------------------------ Hello Ryven, Are you sure the nodes you are loading have culling active? I mean do you setCullingActive(true)?

I have set the perspective using, viewer.getCullSettings().setComputeNearFarMode(osgUtil::CullVisitor::DO_NOT_ COMPUTE_NEAR_FAR); viewer.setSceneData(processed_model.get()); viewer.realize(); viewer.setLensPerspective(40.0, 30.0, 0.5, 1.0); but this way, opengl clips the geometry, but there is no frustum cull by osg, the primitives and triangles are just the same. I can cull if I don't set DO_NOT_COMPUTE_NEAR_FAR, bu this way I can't set the far and near. Can someone help? sorry about the bad english thanks _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
