Image-to-3DPBR TexturesSIGGRAPH 2026SIGGRAPH 2026 paper — generates high-fidelity 3D assets from a single image. Uses pixel-aligned features via back-projection to establish direct pixel-to-3D correspondences, enabling near-reconstruction-level fidelity with detailed geometry and PBR textures. Built on the TRELLIS.2 backbone.
