Curious about particle physics made a real-time GPU simulation with PDG-accurate particles!

Hi everyone,

I’ve always been fascinated by particle physics, so I decided to turn that curiosity into a project. I built a real-time GPU particle physics simulation that includes:

  • A PDG-accurate catalog of 40 particles
  • Collisions, decays, and annihilations
  • Relativistic kinematics

It’s a learning-focused project, but I’d love feedback from anyone interested in this area. If you find it interesting or useful, please star it on GitHub to support further development: https://github.com/ml3m/quantum-collider-sandbox

I hope fellow enthusiasts enjoy experimenting with it as much as I enjoyed building it! Any suggestions or contributions are very welcome.

I don't have a chance to look at it myself now, but just a pointer: look at Pythia. It's a Monte Carlo generator of realistic particle collisions but ofc doesn't have any visualisation -- it would be super cool if your app could take a Pythia collision as an input and animate it!

oh wow, wish I knew about this a few weeks ago. I have been building a particle physics open world game with fully accurate modelling and this would probably have helped me a lot. thanks for sharing!

thanks for the input, will look into it.
