sandbox VS sandbox

I've made a similar game: https://github.com/JMS55/sandbox, and it looks like we've had a lot of the same ideas :)

If you're interested in game development, you may enjoy playing around with Sandbox. It's a game I created where you place sand, water, acid, fire, etc and watch them interact.

> WebGPU is years away to become usable

As a counterpoint, I've been using WebGPU (through wgpu-rs) for the past 1.5 years. It's been a pleasure to use. For instance, here's the CPU-side code for a glow post-process shader using 4 render passes https://github.com/JMS55/sandbox/blob/master/src/glow_post_p....

I've considered implementing Sandbox using wgpu compute sharers (all the rendering is already done with wgpu). The reason I didn't is because I couldn't figure out how to make particles update in parallel - how to handle conflicts between two particles wanting to move into the same position, updating a particle that's supposed to be destroyed, etc. I'd love to get this working however. My last attempt was a the "multithread" branch where I tried to use rayon as a means of prototyping the game using parallel update logic.

Unrelated to a club, but you might enjoy looking at a game I built with Rust + WebGPU https://github.com/JMS55/sandbox.

Not a GSOC project, but my game Sandbox is open to contributions! https://github.com/JMS55/sandbox

Overflowing the stack: Use a Vec, or Box<[T; N]> (boxed array). A boxed array is a heap allocated array, where the box part just points to some data on the heap, so it's cheap to move around. Both are pretty much equivalent, boxed array is maybe slightly more faster/correct. Note that if you use a boxed array, due to some missing compiler optimizations, you'll probably just get a stack overflow anyways, as the compiler will first store the array on the stack, and then copy it to the heap. This can be solved with some unsafe code, such as in https://github.com/JMS55/sandbox/blob/master/src/heap_array.rs.

I'm using a similar approach in my Sandbox engine. And here with arbitrary gravity direction.

I've been exploring compute shaders for cellular automata for the past 3 months in my Sandbox project with deformable objects and customizable matter. Inspired by the likes of Sandspiel and Noita. Time to share some of the progress and get that dear feedback!
