   No combustion has taken place, and so it's cold. [fire_o1.jpg] Oxygen:
   Here's blue will be used to show where there is oxygen. [fire_f1.jpg]
   [fire_h2.jpg] Heat: A small amount of heat generated in the reaction.
   [fire_o2.jpg] Oxygen: Oxygen around the fuel used up. [fire_f2.jpg]
   The accurate rendering of fire is just as important as simulating it's
   motion. Why is fire that colour?
   Fire gives off light for two reasons. Firstly the high temperature of
