How to program fire...graphics

science_geek

ok, so this is one of those stupid things that i came up with just to be an idiot towards my friend. what i want to know is, is there any source of reading out their that can give a basic algorithm on how to program fire. i have looked at the example of a flaming cube in "Processing" and think that would be cool. my goal is not to make something that runs fast and is very realistic but to make fancy colors on a display that kind of mimic the dancing of a flame with some basic shape to it. i am hoping to do this in a slow version with the prop and a quick version with my computer, both versions output to a display which im going to put a black piece of paper around to simulate a ring. this way we can have a fire in the middle of winter...(i know kinda stupid, but he started it)

There are some code that simulates fire floating around... I used to have it some.. 12 or so years ago. Programmersheaven is probably a good start point (web site) for such demos.

I remember that the code meant to produce flames was like: generate a line of random colors and the from the bottom up they would move and change colors according to the selected scale. very simple.

Have you looked at the Processing code? It might give you an idea.

On computers in the 80's, you would probably make a bit mapped drawing:

Get some graph paper and some colored pencils and go to work.· Once you have a drawing you like then devise a way to make the computer draw the pixels that way.

Most difficult may be to use a small palette like the one in the VGA driver.
