●●SolidEye CandyNiche Gem

Compare RK4, Euler, and Verlet integrators side-by-side in your browser.

Strengths
  • •Multiple integration methods let you see numerical stability differences visually.
  • •Export/import data means you can save and share specific orbital configurations.
  • •Figure-8 and Helix presets demonstrate known stable solutions instantly.
Weaknesses
  • •Three-body simulators already exist—this doesn't offer unique physics or features.
  • •No mobile support, and there's no documentation on the math behind each integrator.

A Black Hole Simulator in CUDA C++

The repo actually implements an RK4 geodesic integrator in CUDA kernels to trace millions of rays and produce frame sequences — plus handy scripts to generate a Perlin accretion disk and preprocess NASA EXR star maps. It’s the sort of technical playground that shows real GPU know‑how and produces striking renders, but the experience is experimental: you must manually fetch assets, run preprocessing scripts, and there are no builds, benchmarks or accuracy notes to help anyone reproduce or compare results.
