Never mind; I was able to figure out a solution by studying the osgpackeddepthstencil example and some OpenGL stencil buffer tutorials I found online.
What I did was add a node to the root where I created a geometry the same size as my video projection, and added a Stencil. I also turned off depth testing and set the ColorMask to false. This became my stencil mask. Then, I added two more nodes to the root. Each had a stencil. One was set to draw if the stencil was equal to 1, the other if not equal to 1. To the first node's StateSet I also added the texture I am projecting. To each of these, I added the node which was the root of my model geometry. This caused the video projection to be drawn inside the mask, and the rest of the scene without the projection outside the mask. -Mike ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45638#45638 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
