Added some vertex based ambient-occlusion to the 3D CA demo shader in pst-alpha. Only 3 checks per vertex, and it looks pretty good!

The only tested build target is Emscripten, but I'd be open if you'd like to contribute one for linux, maybe using GLFW.

Yeah. Particle ShaderToy is a tool I've been poking at for a little while.

And here's an optimized version of the original 64^3 CA without internal faces. Should run faster now on integrated GPUs tinyurl.com/tdmrdy5

Ah yes I think this is a bug with the Monaco editor that I’m using. Pretty sure they’ve fixed it. I just need to update to the latest version. Thanks!

Optimized out drawing of internal faces. It runs fast on the Oculus Quest now! (Click "Enter VR" on bottom right)

Also if anyone knows any other cool generations CA rules, I'd love to try them. This 445 rule comes from @SoftologyComAu

Shaders are now linkable in pst-alpha!
Here's a 3d cellular automata example:

Oh also, vertex/fragment varyings are now explicit. You could always add your own, but now it should be obvious.

New updates to pst-alpha✨
- Added a common source tab
- Sim size and vertex count configurable via #pragma
- Simplified shader function arguments (all outs)
- Removed particle coord attribs (just use gl_VertexID)
