"The point is ladies and gentlemen that greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through and captures the essence of the evolutionary spirit. Greed, in all of it's forms - greed for life, for money, knowledge - has marked the upward surge of mankind."
- Gordon Gekko

This is a demo showing how to create a hot air effect with dependent texture reads. First the world is rendered to a texture, then to the screen. Then it creates a fire with a procedural texture. This fire texture is then used both as colors and as an offset of the texture coords for the texture I rendered to. The final result is an effect where it looks like the hot air around the fire refracts the light from the background.
