One of the coolest looking, as well as simplest to achieve, 2D rendering effects is generating flames or fire. This effect combines the use of gradients, palettes, memory manipulation and a technique known as down-sampling to achieve the final result. I’ll provide a brief explanation of  topics I’ve already gone over in previous posts and provide some additional details that are especially reliant to this effect.

This post is going to show in detail how to create this effect using my Rendering Framework project as the foundation.

In my introductory post on Real-time rendering I briefly mentioned that one of the earliest demos was the Starfield effect. This is because the Starfield is generally considered the simplest interesting effect in computer graphics. All you need to accomplish this effect is an efficient plot pixel routine and some basic math.

This post is going to show in detail how to create this simple effect using my Rendering Framework project as the foundation.
