Simple plasma effect

[stripwax]

Just an implementation of the plasma fractal. Works with non-power-of-two dimensions, although end results can look grainy. Feel free to play / use.

I have no idea how that works, but it's awesome. Can I use it in my game?

What is this, I don't even.

No, but really- this is pretty sweet. Where did you get the idea from?

Nice!

Is that using recursive subdivision? I have some Lua code that does that, using diamond-square algorithm, see here: https://github.com/mlepage/heightmap

Thanks,i have been looking for this since some time.

Yep, sure, go for it!

Yep, it is recursive subdivision, not precisely the standard algorithm but more or less the same. I'll take a look at yours too, probably very similar though.

EDIT - yours is probably better; I don't use a power-of-two map (and throw away pieces I don't need), instead I try and work around the non-power-of-two-ness in the recursion itself, which makes my algo more complex (and probably slower than it needs to be) and gives it funny granular artifacts for certain input sizes. Yours is guaranteed to not display such artifacts (at the expense of additional throwaway computation)
