I suppose this would be a good place to ask......something Ive always wondered. I understand the controls on the Projection Plane tab well enough, but on the Primitive tab, under the Pict and Pixel Ratio sliders theres one called Feild of View, which seems adjust the lens distortion similar to the focal length, but on a 1-180 degree scale. Whats this one for and how is it supposed to be used in conjunction with the focal length controls?
