24 alternatives to Black-hole.js – Visualize black hole gravitational lensing in WebGL
Renders black hole gravitational lensing effects in an image canvas using WebGL, glfx.js, and numeric.js - cliffcrosland/black-hole.js
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Black-hole.js – Visualize black hole gravitational lensing in WebGL launched in 2015; newer entries below may have overtaken it.

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…

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 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!

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

Hey there, I'm a big fan of the game Factorio and the beauty of factories in the game. That's why I created a website to artfully visualize Factorio blueprints a few years ago. With the new 2.0 update, a few things broke. I took the opportunity to rewrite everything from Python to JavaScript and support Factorio 2.0 and the Space Age DLC. It's now also possible to easily modify the style of the drawings. Let me know if you find any bugs or if you have ideas for features.

ADS-B visualizer▲339I've created a web app for querying and visualization of ADS-B datasets: https://adsb.exposed/ Source code: https://github.com/ClickHouse/adsb.exposed/ The results significantly exceeded my expectations because the pictures are insanely beautiful, and the data is a treasure trove. It proves many statements that were not certain: - it is feasible to generate tiles by aggregation on a pixel level (instead of hexagons or rectangular grid); - it does not require JPG/PNG tiles - we can transfer raw bitmap data with zstd compression; - it is possible to…

Over the weekend I was discussing the latest news relating to open weights with some of my non-techie friends. After 30 mins of waffling, I realised it is quite a long and interesting story, with many twists and turns. I've always wanted to create a 'long scroll' story, but have never found a suitable story to tell. This felt like a fun weekend project to undertake. The story itself doesn't have too many scroll effects (which is probably a good thing), it was more about trying to tell a story with a certain style that wouldn't really fit on my personal blog. Would love to get your feedback…

Two clip-paths, over the navigation: - The first clip-path is a circle (top-left corner) - The second clip-path is a polygon, that acts like a ray (hardcoded, can be improved) The original work by Iventions Events https://iventions.com/ uses JavaScript, but I found CSS-only approach more fun Here's a demo and the codebase: https://github.com/Momciloo/fun-with-clip-path

I made a GLSL shader that bends 3D space using a 4D hypersphere projection. The idea: 1. Project a model onto a 4D sphere 2. Rotate the sphere 3. Project the model back to 3D Code and details: https://github.com/bntre/CurvedSpaceShader Curious what you think.
