   A Marble Madness-inspired WebGL game we built for Netlify▲616

   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…

    Clocksimulator.com – A minimalist, distraction-free analog clock▲131

    Hello all! Build clean, minimalistic analog clock webpage to Cloudflare Pages. This is for (maybe): - kids to learn - for second monitor - old tabled on shelf - .. Themes and screen wake lock buttons with auto-hide. Goal is to keep it as clean as possible. This possible makes no sense, but for a domain of $10/y this is cheap site for me to keep and see how it lives on.

    VoxelChain – An Experimental Voxel Engine▲118

    VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water). Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the…
