Mathematically Generated Fire – REVISED
Because the first draft of this project has become so popular, I’ve gone ahead and built a new and MUCH faster version. Updates include: DIB sections for flame drawing, look-up tables, optimized randomization, and custom flame coloring. On my old 1.6ghz laptop this version runs over 4x faster than version 1.0. Enjoy!
How to Use Math to Create Fire
Whether working on an old-school RPG or a state-of-the-art FPS, every game programmer needs a fast, cool fire effect at some point in his/her career. In this example, I’ve opted for a straightforward and easy-to-understand method for generating real-time flames. No pre-built images or palettes are used, making the code quite small (only 11kb, including a demo exe) and very easy to reuse. Coloring and flame generation is done using only math and a little cleverness…
