WebGL 2.0 physically-based renderer featuring IBL with environment map convolution, HDR tone mapping, analytical lights, and the metallic-roughness PBR workflow. Implementation based on LearnOpenGL's PBR theory.

I always enjoyed reading video game frame graphics analysis articles and thought it would be cool to write one myself in the hopes that others find it informative and hopefully entertaining.
It covers all the steps needed to produce a single frame in my WebGPU deferred renderer demo. Additionally, it talks about the WebGPU API itself and how it differs in some ways from Metal.

you really think that? I typed it manually myself :D

hey, I turn things off dynamically if the framerate dips below 60fps for longer than 2 seconds. Some people will have them unchecked automatically (and of course have the ability to turn them back on if they really want to)

Hey, OP here. The game is called RAYQUEST, please check it out here: https://rayquestgame.com/

I've put everything I've learned while developing graphics for Apple Vision with the Metal API and Compositor Services in writing. It covers foveation, vertex amplification, stereoscopic rendering, and more techniques that extend beyond this particular device.

All of the game graphics, state and logic are written in WebAssembly Text. The host environment (Javascript) is responsible for:
Game tick loop
User input
Providing characters "0123456789GAMEOVER" byte data on game startup
Blitting the pixel buffer to the display with WebGL2
The game uses 3 virtual pages of memory (64kb each) for a total of 192kb. Within those exist the pixel buffer contents, the characters data and snake positions. For more detailed breakdown you can check src/snake.wat.
The memory is shared between WASM and JS. On each game tick, the pixel buffer region of the memory is transferred to a WebGL2 texture, uploaded to the GPU and blitted to the screen.
