Curt, Have you been successful in implementing your asymmetric frustum hack ? It might be a good idea to add it to the official FlightGear code. It is one of the features that might fill in the gap between "amateur" flight simulation and a professional product. It might even be useful to have any arbitrary frustum, meaning that the screen could have any position with respect to the subject. The difficult part would then be to figure out which parameters to use. Maybe I could try and help with that.
Actually, when I talked about FlightGear at work, our visual systems (screens, projectors, optical systems) specialist asked about asymmetric frustums right away. Not to mention projecting on a spherical surface, which would probably need work in the video board itself, not to mention the drivers and the software part (OpenGL doesn't do it yet, does it ?). For those who might have had trouble understanding (or explaining) what the problem was, I found a page a few weeks ago where it was put quite clearly: http://astronomy.swin.edu.au/~pbourke/projection/caev/ -- Jorge Van Hemelryck _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
