Background

It’s done! (Technically it was done a month ago, I just never wrote about it).

Technical Implementation Notes

• I ended up just sampling the wave functions, and saving it to a JSON file for the web component to read
  • https://github.com/c0nrad/hydrogen/blob/master/hydrogen.cpp#L199
• Originally each point was a three.js sphere, but that ran way to slow, so I got to try vertex/fragement shaders for the first time! (using a THREE.cloud)
  • https://github.com/c0nrad/hydrogen/blob/master/docs/index.html#L44
• The little control panel is actually pretty neat. Just a few lines of code
  • https://github.com/c0nrad/hydrogen/blob/master/docs/app.ts#L24

Overall super happy with it!

Future

Done with this project, but already onto the next! Stay tuned!
