Kim, Thanks very much for the tips and code snippet! Robert, nice to know we were thinking along the same lines for a wowvx stereo option built into OSG ;-) Chris.

However, I have included a function that may help you. You'll have to fill in the rest I'm afraid. The white paper they supply is very good. If you've ever used multiple camera objects in an OSG program you shouldn't find it a problem. The trickiest part in my opinion was creating the class to generate the little header in the top left corner of the image, but that was only because it was fiddly bit shifting. I've only worked with the standard 50/50 stereo image, I believe Phillips support a couple of different formats, one of which splits the screen into 4 that allows you to compensate for the strange blurring effect you get on the edge of objects. As for the blurring in the distance, I get that too, but haven't attempted to fix it, I would imagine dynamically modifying the depth map calculation would go some way to solve this and it's easily done if you use the shader approach that I took. As Robert says there's no need to use any APIs etc, OSG provides all the tools to generate and modify the stereo format in the scene graph. Fire back if you need any further hints or tips. Kim. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
