Meshy is a generative AI platform that converts text prompts and 2D images into textured 3D assets in seconds. It handles automatic character rigging with animation presets, generates full PBR texture maps, and inspects models for watertight 3D printing. It also includes plugins for major tools like Blender and Unity, alongside direct export to standard formats.
This web application provides a sketch-to-3D pipeline built using v0. It takes user drawings, renders them into images with Flux Pro Ultra, turns them into 3D meshes using Hyper3D Rodin, and drops them directly into an interactive Three.js environment. It serves as a practical demonstration of chaining AI generation APIs for rapid 3D asset creation.
img2threejs is an open-source tool and AI coding skill that turns reference images into clean, procedural Three.js TypeScript code without using mesh files or photogrammetry. It runs through agent environments like Claude Code and Codex, employing deterministic Python scripts and vision review gates to build models in token-efficient passes. The output includes structural hierarchies with pivots and sockets, making the generated 3D assets immediately ready for animation in the browser.
TRELLIS.2-4B is an open-source image-to-3D foundation model developed by Microsoft that creates 3D meshes with physically based rendering (PBR) materials from a single input image. It utilizes a sparse O-Voxel representation to support complex topologies, open surfaces, and translucent materials without relying on iso-surface fields. Output meshes can be exported to standard formats like GLB for use in 3D production pipelines.
TRELLIS is an AI-powered 3D generation tool available as an open web demo on Hugging Face Spaces. It transforms single 2D images into detailed 3D models with normal maps and allows users to export them directly as GLB files. It provides a fast, accessible way to test state-of-the-art image-to-3D generation directly in the browser.
Tripo AI converts flat images, sketches, or text prompts into textured 3D models within seconds. It offers engine-ready quad meshes, automated rigging, and model segmentation for 3D printing. It is useful for game developers, animators, and designers needing rapid 3D prototyping without manual sculpting.
World Labs develops spatial intelligence models capable of perceiving and generating persistent 3D environments from 2D inputs. Its flagship tool, Marble, lets users generate, explore, edit, and export interactive 3D worlds from text, images, video, or panoramas. It provides an API and tools for developers building spatial and interactive 3D applications.
World Labs' research demo showcases spatial intelligence AI that generates interactive 3D environments from single 2D images. Users can explore the generated worlds directly in the browser using standard camera and movement controls, viewing both color and underlying depth maps. It represents an early look at creating consistent, explorable 3D scenes without manual modeling.
