In plain words

Black-hole.js is a WebGL-based tool that simulates gravitational lensing effects around black holes on image canvases. Built using glfx.js and numeric.js libraries, it renders realistic distortion and light-bending phenomena that occur near black holes. The project is designed for anyone interested in visualizing complex astrophysical effects through interactive web-based graphics, making abstract physics concepts visually tangible and explorable in a browser environment.

    Physically accurate black hole you can put in your roomJul 2026 · blackhole.plav.in · ▲477

    We have a black hole at home — with actual relativistic physics, live in your browser. I'm Sasha (Alexander) Plavin, an astrophysicist at Harvard's Black Hole Initiative studying quasars and black hole environments. I work with raytracing/radiative transfer simulations professionally, and wanted to make one anyone can play with — so I built this app. Put the black hole onto your screen (any browser), or directly into your room with AR or VR (requires WebXR, for example Chrome on Android, or any VR headset). When looking around, pay attention to unintuitive relativistic effects: rays…

  • A physically-based GPU ray tracer written in JuliaFeb 2026 · makie.org · ▲198

    We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo

  • I was curious about spherical helix, ended up making this visualization2025 · visualrambling.space · ▲865

    I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!
