Write a 3D modeling software from scratch

In plain words

Dust3D is a free, open source 3D modeling software designed for creating low poly models for video games and 3D printing. It automates tedious aspects of character creation by converting 2D sketches into 3D meshes in real time, with built-in UV unwrapping, automatic rigging, and procedural animation tools. Users can assign bone names, adjust animation parameters, and export directly to GLB or FBX formats through a single interface. The cross-platform tool runs on Windows, Mac, and Linux.

Cross-platform 3D modeling software for video games, 3D printing, and more — free and open source. Dust3D automates the tedious parts of 3D character creation — UV unwrapping, rigging, and animation. Sketch a skeleton on a 2D canvas, get a mesh in real time, assign bone names, tune animation parameters, and export. Once Dust3D is running, try the example .ds3 models to get started quickly — open any file via File → Openfrom dust3d.readthedocs.io

  Dust3D 1.0 is finally released — about 10 years after the first commit in December 2016. I posted a preview version here in April 2018 and a beta in December 2018. Back then I thought 1.0 was just around the corner, but I kept adding new features that I could barely find time to finish as a weekend side project. I finally got it done with GitHub Copilot, using models including Claude Opus 4.6, Raptor mini (Preview), Claude Haiku 4.5, and Claude Sonnet 4.6. It's a cross-platform low-poly 3D modeling app focused on making it fast to create game-ready characters and objects from scratch. Source…

  Chili3d – A open-source, browser-based 3D CAD application2025 · ▲408

  I'm currently developing Chili3D, an open-source, browser-based 3D CAD application. By compiling OpenCascade to WebAssembly and integrating Three.js, Chili3D delivers near-native performance for powerful online modeling, editing, and rendering—all without local installation. Access it here: https://github.com/xiangechen/chili3d Features: Modeling Tools: Create basic shapes (boxes, cylinders, cones, etc.), 2D sketches (lines, arcs, circles, etc.), and perform advanced operations (boolean operations, extrusion, revolution, etc.). Snapping and Tracking: Precisely snap to…

  Consol3 – A 3D engine for the terminal that executes on the CPU2024 · github.com · ▲170

  Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

  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…
