hi If you've been ever working with wide-view programs (i.e. FOV of more than 45), you're familiar with the issues caused because of the image distortion at the edges, I know this has something to do with the projection matrix (or even the view matrix?), is there anyway that I can correct this problem, or let me ask my question in this way: Is this kind of problem avoidable or invetable in the computer graphics? I want to have a wide view from a scene (for instance three 45 views) which view (i.e. every 45 view) would be displayed on a separate monitor (or projector); but there are several problems, I cannot creat a single wide view (for instance one 135 degree view) just because of the distortion problem at the edges, and when I create three 45 views showing the different views, another problem shows up, the views aren't alinged correctly, because each shows something different, anyway please help me on this problem thanks in advance friends

A wrote this quite a wile ago, it should be helpful:

The purpose of the article was to allow dividing a perspective into multiple rendered tiles that could be used to compose large scale rendered images, but the math should apply to tiling onto multiple viewports as well.
