4D Gaussian Videos with Motion Layering

Pinxuan Dai*, Peiquan Zhang*, Zheng Dong, Ke Xu, Yifan Peng, Dandan Ding, Yujun Shen, Yin Yang, Xinguo Liu, Rynson W.H. Lau, Weiwei Xu^†

ACM Transactions on Graphics 2025 [ / ]

We reconstruct high-quality, low-storage volumetric video that supports real-time streaming on the Internet.

Neural Shell Texture Splatting: More Details and Fewer Primitives

Xin Zhang, Anpei Chen, Jincheng Xiong, Pinxuan Dai, Yujun Shen, Weiwei Xu^†

IEEE ICCV 2025 [ / ]

We decouple the geometry and appearance of Gaussian splatting for more efficient scene modeling.

High-quality Surface Reconstruction using Gaussian Surfels

Pinxuan Dai*, Jiamin Xu*, Wenxiang Xie, Xinguo Liu, Huamin Wang, Weiwei Xu^†

ACM SIGGRAPH 2024 [ / / ]

We use Gaussian Surfels as geometry primitives to reconstruct mesh surface from multi-view images.

Deep Flow Rendering: View Synthesis via Layer-aware Reflection Flow

Pinxuan Dai, Ning Xie^†

Computer Graphics Forum 2022 [ / ]

We improve reflection synthesis on curved surfaces in image-based rendering using reflection flow.
