Ogre/Mogre: Camera two point perspective

Question

I\'m displaying a scene with some cubes in it. The camera uses persective. Everything works great, but I\'d like the vertical lines to be parallel (two point perspective: ht

Answer 1

The University of Berkeley has a page on the different perspective transformations and the matrices you need to use. The two-point perspective transformation is:

  _                    _
 |  1   0   0 sin(q)/d  |
 |  0   1   0     0     |
 |  0   0   1 cos(q)/d  |
 |_ 0   0   0     0    _|

Where q is the angle used to rotate the points (rather than the axes) and d is unexplained(!) but I think it's the distance of the camera from the focal plane.
