I've had some limited success with OSG and the wowvx display. I used the WowVX OpenGL control - demo downloadable from http://www.business-sites.philips.com/3dsolutions/Downloads/Index.html This control acts as a kind of proxy/wrapper around OpenGL, so in theory can support any OpenGL application without modification. In practice, there were a few problems: 1. The version I downloaded had some kind of incompatibility with the way OSG was initialising OpenGL, but they did send me a update to the control which cured the problem. (not sure if they have updated the download on the site yet) 2. I did need to modify the OSG application to use control's extended API that allows control over the depth map generation in order to get any reasonable 3D effect. 3. There seem to be problems as I zoom into a scene which results in loss range in the depthmap image, but this may be something that can be fixed by dynamically adjusting the parameters in their extended control API. 4. IMHO, the opengl wrapper control costs way too much money!
I think it would be better to try and generate the 2d+depth map images directly from OSG, but I'm not sure what would be involved in this as it seems to rely on sending some kind of control information embedded in the first row of pixels sent to the display. There is documentation about this on the philips site, but didn't have time to look into it deeper. I would have liked to get hold of the sources for the combobulator demo from initon as that seems to use OSG without the OpenGL wrapper control, but again, haven't had time to pursue that either. :-( BTW. You don't need a special Wowvx display driver for it to work, but you do need a supported video card (I think it uses some kind of special DVI protocol that is not always supported) (I used NVidia 7600, but aparently some ATI cards work too) I'd be interested to know if you make any progress with OSG on the WOWvx. If you like, I can post you my changes to osgviewer that set some of the parameters for the Wowvx OpenGL wrapper control, but there was no rocket science involved here.
