Hi, I am working in a research project where the scene is rendered in two TVs with a 120 degree angle between them. The objective is to emulate an hologram using 3d stereo vision and the fishtank formed by the TVs. I am setting each view with different view and projection matrices, similar as described in Generalized Perspective Projection by Robert Kooima, using slave cameras. My questions are regarding the following:
1) Is there any way to set a negative parallax to the entire scene while keeping fixed in the origin? This is necessary to keep the scene fixed, and the only view transforms are the rotation of the view frustums in order to align them with the TVs, as in the paper linked above. I've already tried billboarding, vextex shader program, and setting the fusionDistance. Any good results so far. 2) Is there any way to set the slave projection matrix (using the math described in the link), with non-perpendicular offsets (of the projection pyramid) so I keep the main projection transform in the main camera´s projection matrix (and use the standard slaveCallback, maybe)? Thank you! Cheers, Leonardo Ps.
