I’m currently working on an export script for Sportscar GT tracks and want to export blender camera data.
Jan Walters excellent series of articles on the Blender/python source record that the camera.lens value can be converted to a Field Of View value (radians or degrees - not sure) by:
FOV = 360 * arctan(FACTOR*16/Camera.Lens/PI)
The FACTOR is supposed to be dependant on the X and Y resolution values chosen.
Can anyone please tell me how this FACTOR value is derived and/or what a ‘standard’ value for it would be?
Is possible - does anyone know where it is defined in the 2.25 source - I’ve been hunting in vain!!!.
