About Me
I am currently a final-year undergraduate student at the College of Computer Science and Technology, Zhejiang University, where I built a solid background in computer science and developed a strong interest in 3D vision. I will begin my Ph.D. studies at the Wangxuan Institute of Computer Technology, School of Computer Science, Peking University, in 2025, under the supervision of Prof. Jiahuan Zhou.
My research interest focuses on 3D vision, including scene understanding and generation. I had a wonderful time as an on-site intern at the State Key Laboratory of CAD&CG, where I worked closely with Prof. Zhaopeng Cui on 3D scene reconstruction.

Publications

UPP: Unified Point-Level Prompting for Robust Point Cloud Analysis
ICCV 2025
Zixiang Ai, Zhenyu Cui, Yuxin Peng, Jiahuan Zhou†
- We propose a unified point-level prompting method that reformulates point cloud denoising and completion as a prompting mechanism, enabling robust analysis in a parameter-efficient manner.

Vision Graph Prompting via Semantic Low-Rank Decomposition
ICML 2025
Zixiang Ai, Zichen Liu, Jiahuan Zhou†
- In this paper, we propose Vision Graph Prompting (VGP), a novel framework tailored for vision graph structures. Our core insight reveals that semantically connected components in the graph exhibit low-rank properties.

GAPrompt: Geometry-Aware Point Cloud Prompt for 3D Vision Model
ICML 2025
Zixiang Ai, Zichen Liu, Yuanhang Lei, Zhenyu Cui, Xu Zou, Jiahuan Zhou†
- In this paper, we propose a novel Geometry-Aware Point Cloud Prompt (GAPrompt) that leverages geometric cues to enhance the adaptability of 3D vision models.

GURecon: Learning Detailed 3D Geometric Uncertainties for Neural Surface Reconstruction
AAAI 2025 (Oral)
Zesong Yang*, Jiale Shi*, Ru Zhang, Zixiang Ai, Boming Zhao, Hujun Bao, Luwei Yang, Zhaopeng Cui†
- In this paper, we present a novel framework, i.e, GURecon, which establishes a geometric uncertainty field for the neural surface based on geometric consistency.
