trimesh

A generic programming header only C++ library for processing polygonal and polyhedral meshes

KeyForge3D is an app that turns a photo of a key into a 3D-printable STL file. Ideal for locksmiths and hobbyists, it analyzes the key's bitting pattern using image processing and generates an accurate 3D model for quick replication.

This is a method of curvature estimation on triangular mesh

TRELLIS.2-Text-to-3D is an end-to-end Text-to-3D and Image-to-3D generation app that enables users to create high-quality 3D GLB assets either by generating an image from a text prompt or by uploading an existing image, powered by Z-Image-Turbo and the TRELLIS.2 multi-stage pipeline.

A lightweight 3D visualizer built with Flask and Three.js. It lets you render meshes, point clouds, frustums, and coordinate axes in the browser — all controlled live via a Python API.

Parviz, your desk AI: a 3D-printed tank-tracked robot with a Raspberry Pi touchscreen face, a camera eye, and a self-locking pan/tilt neck.

Turn a photo into a 3D-printable STL. Four backends behind one interface — watertight, scaled in millimetres, validated against your printer.
