   ChartGPU – WebGPU-powered charting library (1M points at 60fps)▲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:…

   Unity like game editor running in pure WASM▲644

   In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds&#x2F;levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

   I built an indie, browser-based MMORPG▲340

   I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https:&#x2F;&#x2F;poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

    Typescript library for editing videos with code▲20

    Today we launched a Typescript library for building video processing applications that can run completely client-side This project has been started in March 2023 with the mission of creating the "video processing toolkit for the area of AI". During an extensive research period, we quickly decided to fully embrace WebGPU, which offers a substantial performance improvement over its predecessor WebGL and technologies alike. In combination with WebCodecs, these two technologies lead to unprecedented rendering capabilities on the web and pave the way for the next generation of video processing…

    Svader – Create GPU-rendered Svelte components▲189

    Svader is a library for rendering 2D shaders on Svelte websites, using either WebGL or WebGPU. It's streamlined for the specific use case of rendering 2D graphics using fragment shaders as an alternative to SVG or the JS canvas API, so it's not meant for doing 3D objects like three.js, for example. This started as something I needed for my own project, but I eventually decided to split it into a separate library. I've since found that this use case fits really well into the Svelte compiler-based approach and its fine-grained reactivity system. In general, I think using shaders like these has…

    a Rust ray tracer that runs on any GPU – even in the browser▲95

    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 reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be…

    A Node Based Editor for Three.js Shading Language (TSL)▲7

    Three.js recently introduced TSL (Three.js Shading Language), a way to write shaders in pure JavaScript&#x2F;TypeScript that compiles to both GLSL and WGSL. I built this editor to provide a visual interface for the tsl ecosystem. It allows developers to prototype shaders for WebGPU&#x2F;WebGL and see the results in real-time. This is a beta release and I'm looking for feedback.
