a Rust ray tracer that runs on any GPU – even in the browser

In plain words

This is a ray tracer built in Rust that runs on any GPU, including in web browsers via WebAssembly. It renders 3D scenes with photorealistic lighting by simulating direct and indirect illumination, using a Bounding Volume Hierarchy for fast mesh rendering. The tool works both as a local application and as a deployable web demo, making it suitable for developers interested in graphics programming and exploring Rust's performance-oriented features.

git clone https://github.com/tchauffi/rust-raytracer.git cd rust-raytracer cargo run --bin live_raytracer --release Use your mouse to rotate the camera and press SPACE to toggle rendering modes! Whether you're learning about ray tracing, exploring Rust graphics programming, or looking for a starting point for your own renderer, this project provides working examples of multiple rendering approaches. The CPU version renders scenes using traditional CPU-based raytracing and outputs to a PPM image file. Best for learning how raytracing works under the hood. # Build and run (outputs to stdout, redirect to file) cargo run --release > output.ppm # Or build first, then run cargo build --release…from github.com

In the maker’s words, at launch

I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch. The initial goal was just to render a simple 3D scene in the browser at a…

  ChartGPU – WebGPU-powered charting library (1M points at 60fps)Jan 2026 · github.com · ▲670

  Creator here. I built ChartGPU because I kept hitting the same wall: charting libraries that claim to be "fast" but choke past 100K data points. The core insight: Canvas2D is fundamentally CPU-bound. Even WebGL chart libraries still do most computation on the CPU. So I moved everything to the GPU via WebGPU: - LTTB downsampling runs as a compute shader - Hit-testing for tooltips/hover is GPU-accelerated - Rendering uses instanced draws (one draw call per series) The result: 1M points at 60fps with smooth zoom/pan. Live demo:…

  I've made a Monte-Carlo raytracer for glTF scenes in WebGPU2024 · github.com · ▲131

  This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

  I made a WebGL-based app that traces images using circles2022 · phqb.github.io · ▲93

  I was fascinated by this [0] and this video [1]. After many struggles, I finally built this app that traces images using circles similar to what these videos had shown. The most challenging part (to me) is to find a way to convert images to vector lines. I had tried Potrace, but its output is not suitable for my use case: too many small elements share the same border. Potrace's goal is to represent the original image faithfully using vector lines. But I want to trace the image edges. After searching and trying some Potrace alternatives in vain, I finally found my keyword. Surprisingly (to…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
