GLSLife

2009.01.31 in code

Hey! Following Robb's recent blog post about an implementation of Life as a GLSL shader, I now present to you a Mac OS X screensaver in the same style (using his shader and the original GPULife source).

Watching it near stability is half the fun. Just when you think you are there, a little glider thing comes along and messes up some order somewhere else. It doesn't become uninteresting as fast as you would think.

If you must inject cells, can I suggest adding in gliders? It seems more "natural" that way.

Tim

Sure, sure. But it reaches /actual/, complete stability very quickly. It's not clear why. Adding in gliders is a good idea - I'll do that, too :-D

Tim

Yeahhhh I don't know much about screensaver stuff, I might add options like that at some point. However, you do realize that if it doesn't add more cells, it /will/ die (to a completely stable state) after a (rather short) while? Maybe coming up with a better way to do it would be better. I should look at Robb's...

Rainbow background should be an option, I agree. Next "release", perhaps!

Should make framerate an option too (it /can/ go faster, and it would be nice if it could be slower). And Robb likes scaling (so that each cell is 2 square pixels), etc.

I'll put it in bzr and work on stuff tomorrow or Sunday.

The trails really add a lot. Its a great screensaver.

But, I don't like the way it randomly adds in more cells. You should have that be an option. And the rainbow background should be an option too.
