CNS-Edit: 3D Shape Editing via Coupled Neural Shape Optimization

no code implementations4 Feb 2024 Jingyu Hu, Ka-Hei Hui, Zhengzhe Liu, Hao Zhang, Chi-Wing Fu

First, we design the coupled neural shape (CNS) representation for supporting 3D shape editing.

Make-A-Shape: a Ten-Million-scale 3D Shape Model

no code implementations20 Jan 2024 Ka-Hei Hui, Aditya Sanghi, Arianna Rampini, Kamal Rahimi Malekshan, Zhengzhe Liu, Hooman Shayani, Chi-Wing Fu

We then make the representation generatable by a diffusion model by devising the subband coefficients packing scheme to layout the representation in a low-resolution grid.

Semi-signed prioritized neural fitting for surface reconstruction from unoriented point clouds

no code implementations14 Jun 2022 Runsong Zhu, Di Kang, Ka-Hei Hui, Yue Qian, Xuefei Zhe, Zhen Dong, Linchao Bao, Pheng-Ann Heng, Chi-Wing Fu

To guide the network quickly fit the coarse shape, we propose to utilize the signed supervision in regions that are obviously outside the object and can be easily determined, resulting in our semi-signed supervision.
