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.
