"Angle" does do just that. Basically, reducing the camera angle reduces the
perspective effect; angle -> infinity approaches orthographic projection.
Remember that reducing the camera angle reduces the FOV (Field of View). So if
you want a particular object to appear the same size as before, you need to
increase the distance between it and the camera.
