WebGL2 front-end + WASM backend = full software GPU

[mihailik]

NPM WebGL2 module: https://www.npmjs.com/package/webgl2
Code on GitHub: https://github.com/mavity/webgl2
Demo: https://webgl2.was.hm/

Why

I've started on this project because I need heavy duty unit-testing and debugging tool for WebGL2 rendering. N-body problem calculation with all sorts of stretch targets.

Having struggled for a while, I looked around and turns out naga can be a building block around which I can build a predictable WebGL platform

What is it

I aim to implement WebGL2RenderingContext in WASM for both browser and node.js

Currently I have a proof of concept, and it works suprisingly well: 20FPS on cheap phone¹

I made a couple opportunistic tweaks to naga/fork to parse WebGL2 syntax better.

Where next

To make it properly useful to me I need a bunch more work:

• full GLSL/WebGL2 parser (naga frontend)
• full IR->WASM generator (naga backend)
• WASM symbolicator and test runner for node.js

Plenty of work, but none of the rocket science type. This prototype lays the key groundwork.
