I've dug around in the lists and various other areas and have yet to come up with a solution.
We have a cylindrical display using 3 projectors with a viewing angle of 225 degrees. Most of the code is based off of osgdistortion, but I can't seem to get a very large FOV. I've tried several approaches: 1. Setting the viewing angle of the master camera to perspective with the large FOV. Works up to 140 degrees but after that the perspective is to distorted (as would be expected). Interestingly, at FOV > 180, the up vector flips and the FOV gets smaller (somewhat expected if you think about the math). 2. Setting the offset parameters in addSlave (strange results) What I think I need is to set each one of the three views to have a viewing angle of 75 degrees, and to rotate two of the views +/- 75 degrees from the center. Any help/hints on setting this up would be appreciated. Mark Mark A.
