MeshCrunch
3D meshes: inspect, simplify, rebuild, and generate LODs
What it does
MeshCrunch is a toolkit for getting heavy 3D assets ready to ship. Inspect meshes, reduce polygon counts, generate LOD chains, rebuild broken geometry, convert formats and create turntable previews — from a visual Studio or through MCP for AI-assisted workflows. Built for game, web and XR pipelines.
MeshCrunch reduces 3D mesh polygon counts with quadric-error decimation and generates LOD chains, with turntable GIF/MP4 export that runs entirely in the browser. Accepts OBJ, STL, GLB, glTF, PLY and OFF. Built for game, web, and XR pipelines.
MeshCrunch simplifies meshes and generates LOD chains, writing the result as OBJ, STL, GLB, PLY or OFF — so your games, web scenes, and XR apps load in a fraction of the time. Purpose-built for optimizing polygon-heavy assets before they reach real-time renderers. Reduce triangle count with quadric-error decimation while preserving the silhouette. Compare original and optimized side by side, with exact triangle and file-size savings. Turn one high-poly asset into a full level-of-detail ladder in a single request, each level decimated from the original. Download individually or as one ZIP with a manifest. Wrap a new closed surface around a model the decimator cannot fix — holes,…from meshcrunch.com

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
