JPIN Posted March 9, 2010 Share Posted March 9, 2010 Hi everybody A question about Vray / Physical camera: according to the theory, the FOV (Field of View) is determined by the ratio "film gate" / "focal length". However I have noticed that if both "film gate" and "focal length" are multiplied with the same coefficient, while all the other parameters of the physical camera remain intact, FOV is affected. Specifically FOV narrows as the coefficient is increased. Does anybody know the mathematical relation among "film gate", "focal length" and FOV?

andstef Posted March 9, 2010 Share Posted March 9, 2010 Hello, I don't know the mathematical relation, but I am just curious why is that important? Vray physical camera emulates a real camera, why would you need FOV?, you don't have that on a real camera. Link to comment Share on other sites More sharing options...
kikopeligro Posted May 24, 2010 Share Posted May 24, 2010 maybe too late ... 36.0/(2.0*tan(0.5*FOV*180.0/3.1415)) Link to comment Share on other sites More sharing options...
