Stop losing your design details in canonical space
Most 3D-native generators guess your asset's shape in a generic pose using loose attention mechanisms, resulting in blurry details. Pixal3D directly generates 3D in a view-consistent way, locking in every pixel to establish direct, unambiguous correspondence.
Unmatched Detail & PBR Materials
Generate high-resolution meshes equipped with Physically Based Rendering (PBR) textures that react accurately to lighting in any engine.
From Single Object to Scene Synthesis
Not just for isolated props—Pixal3D’s modular pipeline can parse complex images into high-fidelity, object-separated 3D scenes.
Why Pixal3D outperforms traditional 3D generators
3D artists, game developers, and spatial computing creators don't just want a shape—they want a production-ready asset. Pixal3D bridges the gap between instant AI generation and professional 3D reconstruction.

Frequently asked questions
Everything you need to know about Pixal3D's groundbreaking technology, capabilities, and outputs.
Pixal3D is a pixel-aligned 3D generation paradigm that creates high-fidelity 3D assets from images. By directly generating 3D in a way that is consistent with the input view, it achieves superior pixel-level faithfulness compared to traditional generators.
Most 3D-native generators synthesize shapes in a 'canonical space' (a generic pose) and loosely inject image cues via attention, causing a loss of detail. Pixal3D explicitly lifts multi-scale image features into a 3D feature volume via back-projection, establishing direct pixel-to-3D correspondence.
Yes! While it works wonderfully with a single image, Pixal3D naturally extends to multi-view generation by seamlessly aggregating back-projected feature volumes from different angles.
Pixal3D generates ready-to-use GLB meshes, complete with detailed geometry and Physically Based Rendering (PBR) textures.
Yes. Pixal3D includes a modular pipeline designed to produce high-fidelity, object-separated 3D scenes directly from images.
Pixal3D was developed by Dong-Yang Li and researchers from Tsinghua University in collaboration with TencentARC. The research was accepted to SIGGRAPH 2026.
You can try Pixal3D directly in your browser without any installation using our Hugging Face Gradio demo. If you want to run it locally via the GitHub repository, a modern dedicated GPU is recommended.
The original paper utilized Direct3D-S2, but the latest, improved open-source implementation is built upon the highly efficient Trellis.2 backbone.
