NOTE:

I forgot to upload my last particle sim, failed hardrive lead to missing works. So I must completely restart This is a complete work in progress and will be appended to, if not completely modified after the inital simulation is completed

What

This is an N-body particle sim that will be using cpp and native webgpu bindings.

Why

The last particle sim I implemented was single threaded and of a single type of particle, I am planning on using this as a base for a fluid simulation for a lava lamp sim. I choose webgpu in particular, so that I may reuse that code to export the lava lamp simulation to the interwebs. I can then use that lava lamp as a background/screen saver.

TODO:

1. [x]AABB trees
2. [x]Particle single threading
3. [x]Particle multithreading
4. [x]Webgpu particle display
5. [x]Port particle physics to webgpu compute shader
6. []Heat??
7. []Density??
8. []Surface tension??
9. []Multiple particles for different fluids

MAKE IT RUN

Building

git clone --depth 1 https://github.com/google/dawn.git  # if dawn/ dir is missing
mkdir -p build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)

First build is slow because of Dawn compilation. Subsequent builds are fast.

Usage

./ParticleSim
