Sparse‑Up: Sparse‑Voxel 3D Geometry Generation Boosts Product Reconstruction

The paper presents Sparse‑Up, a sparse‑voxel based 3D geometry generation framework that introduces learnable surface‑anchored upsampling and view‑partition rendering to eliminate redundant points, dramatically reduce memory usage, and achieve high‑fidelity product reconstruction, with experimental results surpassing TRELLIS, Hunyuan3D and other SOTA methods.

How Microsoft’s Open‑Source TRELLIS.2 Generates Full‑Texture 3D Assets in 3 Seconds

The article analyzes the fundamental challenges of 3D generative AI, compares existing NeRF, voxel, and single‑view methods, and explains how Microsoft’s open‑source TRELLIS.2 uses a field‑free O‑Voxel representation and 16× compression to produce 512³ full‑texture assets in about three seconds, with a step‑by‑step HyperAI demo.
