Pixal3D: Pixel-Aligned Image-to-3D Generation Accepted at SIGGRAPH 2026
Tencent ARC Lab
Pixal3D introduces a pixel-aligned image-to-3D generation paradigm accepted at SIGGRAPH 2026. Instead of loosely injecting image features via attention, it explicitly lifts multi-scale pixel features into a 3D feature volume via back-projection, establishing direct pixel-to-3D correspondences and enabling near-reconstruction-level fidelity with detailed geometry and PBR textures. Code, demo, and HuggingFace model were released simultaneously.
