My name is Chong ZENG 曾充, and usually use the name NCJ in open-source communities. Currently I am a master student majoring Computer Science and Technology at Zhejiang University, supervised by Prof. Hongzhi Wu. I am currently a visiting graduate at UC San Diego, fortunate to be advised by Prof. Hao Su. Previously, I'was fortunate to work closely with Dr. Yue Dong as a research intern at Microsoft Research Asia. Before that, I received my bachelor's degree at College of Computer Science and Technology, ZJU. My research interests include Computer Graphics and 3D Vision, specifically, 3D object geometry and appearance modeling and generation.

Projects


ZJU GitZJU's Git service. I worked as the project leader, helped deploy and maintain this platform for all students and faculty in ZJU.

GNC
[Repo] [Online Demo]
GNC (GNC is not C) is a toy compiler written in Rust and is ported to pure frontend via WebAssembly. To overcome the limitations of LLVM, I wrote a JS runtime called HLVM which takes AST as IR and interprets it. An visualization tool is also available.

Overfit-SDF
[Repo]
Use neural network to overfit 3D object's SDF geometry representation, implemented in PyTorch.
AI-Seal Project
[Online Demo] [More]
One of my web development projects featuring AI-driven Seal Generation, I implemented the backend system, a background management system (with frontend), and deployed all of these.
