Single-image scene mesh generation with adaptive chunks and explicit 2D–3D conditioning outperforms all baselines on indoor and outdoor reconstruction
The work redesigns the object-centric 3D generator Trellis 2 with adaptive chunks that scale with camera distance, explicit 2D–3D conditioning that lifts image features onto observed surfaces while distinguishing free space from occluded regions, and supervision from about 4,000 synthesized outdoor scenes, generating a complete scene mesh from a single image and outperforming all baselines in geometric accuracy and perceptual quality on Tanks and Temples, ScanNet++, and 121 in-the-wild images.
