Is that somehow feasible?
That's essentially what we do. Our window is 3840x1080, with two viewports of 1920x1080. Our computer sees that as a single monitor of 3840x1080, and uses a Matrox TripleHead2Go to split it across the two projectors. (The regular desktop monitor serves as a second monitor.) I have no idea whether 3840x1080 will work with your 3D monitor. I guess there's no harm in trying, and see what happens. Does the monitor support alternative formats? Is it active stereo? Interlaced? (Back in the 90's I worked with SGI workstations that split the screen vertically for stereo. The "low cost" Indys and Indigos didn't have separate left-right stereo buffers, so they used the top half of the mono buffer for the left eye and the bottom half for the right eye and doubled the vertical scan rate, creating frame-sequential stereo with non-square pixels, 1:2 aspect ratio. OpenInventor understood the setup and handled the OpenGL projections, but other bits of software had to account for the rectangular pixels, similar to what you describe.) -- Ted ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
