Has anyone ever played with shutter glass support via JMonkey engine ? I did a search, but it didn't turn up anything concrete, apart from some cave stuff.
Unfortunately special hardware is required so not much was done in that area. If you’re using a GeForce GPU, you can use the nVidia Stereo 3D driver to run applications in 3d stereo. Otherwise you have to use the driver included with the shutter glasses(?) together with OpenGL stereo display mode, currently jME does not support it but it can be added.
