# Trellis 2

> 3D AI Model by Microsoft — available on Layer

Open-source, high-quality 3D model from Microsoft, leveraging a novel field-free sparse voxel structure.

Trellis 2 is a state-of-the-art large 3D generative model designed for high-fidelity image-to-3D generation. It leverages a novel field-free sparse voxel structure termed O-Voxel and a large-scale flow-matching transformer (4 Billion parameters). Unlike previous methods that rely on iso-surface fields (e.g., SDF, Flexicubes) which struggle with open surfaces or non-manifold geometry, TRELLIS can reconstruct and generate arbitrary 3D assets with complex topologies, sharp features, and full Physical-Based Rendering (PBR) materials—including transparency/translucency.
