Pixal3D

Generate pixel-perfect 3D assets from any 2D image in seconds. Open-source image-to-3D model with PBR textures and GLB export.

About Pixal3D

Pixal3D is an open-source tool designed to generate high-fidelity 3D assets from single or multiple 2D images. Developed by researchers at Tsinghua University and TencentARC, it uses a pixel-aligned back-projection approach to create geometry and physically based rendering (PBR) textures that closely match the input images. The tool supports exporting models in the GLB format, making them compatible with popular 3D engines. Pixal3D is suitable for artists, game developers, and researchers who require accurate and production-ready 3D models. The code is available under the MIT license, and a web demo is provided for immediate use.

Best for: 3D artists, game developers, AI researchers, technical artists
