I think I answered my own question by just doing it. BTW, it appears that the graphics context is bound and I'm able to capture what the camera see's, process it, and render the processed image.

It provides an FBO for rendering the scene to, processes the captured scene, and then will render the FBO when completed. I would like to change the way we use it in OSG to make it work closer to the osg::Camera class. My first thought was to derive a Camera class and override the applicable functions. At first glance, this appears a bit more involved than I really hoped. While looking at the Class I see (and now remember) Pre and Post draw calls. My big questions are: 1. Is the graphics context bound when these calls are made? (if not, why not) 2. If so, am I allowed to bind my FBO in the pre-draw, and draw in my post draw? Thanks! --- Brad Colbert Renaissance Sciences Corporation _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
