You can transform POV-Ray's camera just like any object, e.g.:

camera {location <0 ,0, 0> look_at  <0, 0, 1>
    rotate z*30 // Roll around viewing axis
    rotate <35, 135, 0> // Tilt and pan
    translate -x*20 rotate y*clock*360 // spin around y-axis
    }

When you use rotate and translate commands like this, POV-Ray keeps the
three camera vectors (direction, right and up) orthogonal, so the camera
view is not distorted.
