24 alternatives to Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision
I built Seed3D, a next-generation 3D reconstruction and modeling tool that turns 2D inputs into solid, physics-ready 3D models — with millimeter precision, physically accurate PBR materials, and export formats ready for any major engine. Unlike traditional photogrammetry or AI mesh tools, Seed3D doesn’t fake geometry with normal maps — it reconstructs real surfaces, edges, and micro-details for simulation-grade accuracy and realism. What it does • Generates watertight polygonal meshes with crisp, true geometry • Outputs full PBR texture sets (albedo, roughness, metalness, normal, AO) •…

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…

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…

I ported Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS. The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac. I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files. Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as…

I'm the co-creator and maintainer of https://aframe.io/ and long time Web 3D graphics dev. Super excited about new techniques to author / render / represent 3D. Spark is a an open source library to easily integrate Gaussian splats in your THREE.js scene I worked with some friends and I hope you find useful. Looking forward to hearing what features / rendering techniques you would love to see next.

3D-to-photo is an open source tool for Generative AI product photography, that uses 3D models to allow fine camera angle control in generated images. If you have 3D models created using the iOS 3D scanner you can upload them directly on to 3D-to-photo and describe the scene you want to create. For example: "on a city side walk" "near a lake, overlooking the water" Then click "generate" to get the final images. The tech stack behind 3D-to-photo: Handling 3d models on the web: @threejs Hosting the diffusion model: @replicate 3D scanning apps: shopify,Polycam3D or LumaLabsAI

To my knowledge, this is the first formally verified implementation of a 3D constructive solid geometry (CSG) operation: mesh intersection, implemented in Lean 4 and verified against a concise specification that pins down the surface of the resulting mesh exactly and guarantees practical well-formedness conditions on the triangulation. This project is also an experiment in avoiding having to trust AI-generated code. A human reviewer only needs to read 93 lines of formal specification and run the Lean checker to certify the correctness of the kernel, skipping the intricate 1000+ lines of…
