The ProceduralFire sample demonstrates the use of pixel shaders to

procedurally generate natural phenomena such as fire.



Rendering fire as an animation has the disadvantages of looking unrealistic

due to the cycling animation and of requiring a lot of texture memory to

store the frames of animation. In addition to this, if there are many

flames in the scene, and all use the same animation, the scene will look

even more artificial.



The procedurally generated fire overcomes all these disadvantages by

generating long non-repeating animations that can be fully controlled by

the application and requires only two textures. The sample uses 1.4 pixel

shader to implement the effect.
