Learning based 2D Irregular Shape Packing

no code implementations19 Sep 2023 Zeshi Yang, Zherong Pan, Manyi Li, Kui Wu, Xifeng Gao

2D irregular shape packing is a necessary step to arrange UV patches of a 3D model within a texture atlas for memory-efficient appearance rendering in computer graphics.

RIM-Net: Recursive Implicit Fields for Unsupervised Learning of Hierarchical Shape Structures

1 code implementation CVPR 2022 Chengjie Niu, Manyi Li, Kai Xu, Hao Zhang

Each level of the tree corresponds to an assembly of shape parts, represented as implicit functions, to reconstruct the input shape.

D2IM-Net: Learning Detail Disentangled Implicit Fields From Single Images

no code implementations CVPR 2021 Manyi Li, Hao Zhang

We present the first single-view 3D reconstruction network aimed at recovering geometric details from an input image which encompass both topological shape structures and surface features.
