## Leaving this repo for reference, but see updated version at: http://rreusser.github.io/demos/smooth-life/

A quick implementation of SmoothLife on the GPU using [regl](https://github.com/mikolalysenko/regl). GPGPU has never been so easy. As far as WebGL goes, this is little more than a trivial modification of Mikola's [Game of Life](https://github.com/mikolalysenko/regl/blob/gh-pages/example/life.js) example.

It's pretty inefficient since it's brute-forcing the convolution. It's unrolling the loop as intelligently as possible (I suspect the compiler is probably good enough to remove all precalculatable floating point multiplications and loop branches anyway), but I really need to figure out GPU FFT. It might actually be faster to do this in plain js, but it was a great REGL learning experience (though admittedly most of the time was just spent tweaking the parameters trying to get anything interesting. I guess it was mostly just fun is what I'm trying to say).

See demo at: [http://rreusser.github.io/regl-smooth-life](http://rreusser.github.io/regl-smooth-life)

But for a better implementation, see: [smoothnacl](https://github.com/binji/smoothnacl/) from the [PNaCl Demos](https://gonativeclient.appspot.com/demo) site.
