I have encoutered a funny trick with LinearFog. Instead of the effects of the fog being bounded between the front and back distance, these distances seem to bound an area where the fog will have no effect; the fogs affects the scene from the stop bound to negative infinity, and from the start bound to positive infinity. Switching the start and stop distances changes nothing. Using imediate mode rendering, distances are between -1 and 1. Any help on this sillyness?
