Quest for Fire

By no means a gamer myself, I’ve always been interested in the math behind the graphics in video games. A previous post showed how simple clouds can be produced by the Diamond-Square algorithm, running on an esp8266. That algorithm can generate maps and landscapes as well.

Another visual effect on my todo list was algorithmically simulated fire.


The video shows my first attempt on a small TFT display. I had to write a relatively simple algorithm, because it needs to run on a microcontroller. Some further experimenting with the color┬ápalette, weighting factors and randomization, as well as adding Perlin noise, will hopefully result in a more realistic fire. I also plan to add a rotary encoder for regulating the ‘fire’.
