Sorry for the confusing title. I have a flight simulation that uses multiple monitors to mimick different airplane windows. For instance, left-front, right-front, left-side, etc.....
There is an annoying phenomenon that occurs particularly when pitching. If you are in the air, and level, you can see the horizon, and everything is good. If you pitch towards the ground, the horizon rises towards the top of the monitor. The problem is, that it bends from monitor to monitor. >From left-front to right-front, the horizon (and of course the rest of the scene) will bend in the form of an upside-down "V" I think that this is due to having two flat projected images pitch on different pivot points, creating the bend at the top. A good approximation to this effect is to hold your hands in front of you, palms facing you, thumbs on top, with the middle fingers touching. Now bend your wrists to pitch-up. You get an inverted "V". That mirrors the effect. I need something similar to not pitching my wrists, but moving my arms up so that the entire image moves without bends. I don't have the simulation here, or I'd attach pictures. I think what I have described is a single pivot point, instead of multiple, but I am not sure. Any suggestions for how to implement this, or what is involved in doing so? Is this simply a projection matrix issue, or an eyepoint problem? Thanks for any help, and sorry again for the long explanation. If there is a name for this effect, I'd like to know it.
