CPU Shadertoy

Run shadertoy shaders on CPU with multithreading and SIMD. Just for fun and learning about ISPC, the Intel SPMD program compiler.

With this project, you can just copy-and-paste shadertoy shaders, run it on CPU with no or little modification, and get high performance.

This project is highly inspired from zigguratvertigo's hlsl-to-ispc.

This project is still incomplete and working in progress.

Performance

I got around 18FPS, running "Glow City" on my Intel Core i7-7700K. As a comparison, around 31FPS when using GPU(HD 630) on shadertoy.com(Chrome).
