LDM: Large Tensorial SDF Model for Textured Mesh Generation
Rengan Xie, Wenting Zheng, Kai Huang +5
Previous efforts have managed to generate production-ready 3D assets from text or images. However, these methods primarily employ NeRF or 3D Gaussian representations, which are not…
2L3: Lifting Imperfect Generated 2D Images into Accurate 3D
Yizheng Chen, Rengan Xie, Qi Ye +5
Reconstructing 3D objects from a single image is an intriguing but challenging problem. One promising solution is to utilize multi-view (MV) 3D reconstruction to fuse generated MV…
In-Hand 3D Object Reconstruction from a Monocular RGB Video
Shijian Jiang, Qi Ye, Rengan Xie +4
Our work aims to reconstruct a 3D object that is held and rotated by a hand in front of a static RGB camera. Previous methods that use implicit neural representations to recover th…
Holistic Inverse Rendering of Complex Facade via Aerial 3D Scanning
Zixuan Xie, Rengan Xie, Rong Li +8
In this work, we use multi-view aerial images to reconstruct the geometry, lighting, and material of facades using neural signed distance fields (SDFs). Without the requirement of…
