This seemed to work for me: Osg::StateSet* state = geode->getOrCreateStateSet();
Osg::Depth* depth = new osg::Depth(osg::Depth::Function::ALWAYS); state->setAttribute(depth); -Or- state->setRenderBinDetails(11,"RenderBin"); -Or- state->setMode(GL_DEPTH_TEST,osg::StateAttribute::OFF); state->setRenderingHint(osg::StateSet::TRANSPARENT_BIN); Have not tested lately Hope this helps -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pecoraro, Alexander N Sent: Thursday, July 26, 2007 6:24 PM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Clear depth buffer I was wondering if anyone could offer me a suggestion on how to force a clear of the depth buffer in the middle of a rendering pass. I have a 3d model that I want to show up right in front of the viewer and always be on top. I used a absolute reference frame transform node and an orthographic projection node to put the model in the middle of the screen, but now when my viewer gets too close to other models they peek through. I figure if right before I draw my orthographic model I clear the depth buffer then I would guarentee that nothing would get draw on top of my model (as long as I draw my model last). I found that I can't just disable depth testing on the model because then the various pieces of the model don't get drawn in the right order and so certain pieces end up on top of pieces that they shouldn't end up on top of. Any help? Thanks.
