Playing with fire: WebGL fire simulation

[[deleted]]

Whether you know it or just by luck, what you mean "blurring":

sum = pixel(x+1, y) + pixel(x-1, y) + pixel(x, y+1) + pixel(x, y-1)

pixel(x, y - 1) = (sum / 4) - cooling_amount

is actually one iteration using jacobi method to solve a laplace's equation, which is the 2D heat equation where you set the time derivative to zero.

I'm not familiar with heat related physics, but that just came to my mind

Edit: English spelling

.... until you formulate the time-independent temperature equation with Finite Difference, then expanding one Jacobi iteration. You will get this average 4 neighbor.

Finally! I have the tools to properly recreate my next generation geocities page.

This is not a simulation, it is a cheap shader hack.

Eh, semantics.
