Guying Lin

I'm a first year PhD student in the Computer Science Department at Carnegie Mellon University supervised by Prof. Minchen Li. Previously, I earned my M.Phil. from the University of Hong Kong, where I was supervised by Prof. Taku Komura and Prof. Wenping Wang. Prior to that, I obtained my B.Eng. (Hons) from Zhejiang University.

Research

I am generally interested in the intersection of computer graphics and computer vision. Currently, I'm working on 3D reconstruction / generation with physical constraints.

A unified neural implicit representation that models complex shapes efficiently, preserves sharp features, and effectively models surfaces with open boundaries and thin geometric features.

Studying the optimal sampling problem in network training for modeling neural implicit surfaces, especially those with rich geometric details.

An effective representation that enhances 2DGS for large image fitting through optimized strategies and a Level-of-Gaussian approach.

A Progressively-connected Light Field network for the novel view synthesis of complex forward-facing scenes which is able to achieve significantly better rendering quality than the vanilla neural light fields and comparable results to NeRF-like rendering methods.

A robust and efficient method to extract a high-quality surface from neural unsigned distance functions (UDFs).

The first piecewise neural surface representation that allows coarse patch layouts of arbitrary n-sided surface patches to model complex surface geometries with high precision, offering greater flexibility over traditional parametric surface.

Miscellanea

In addition to graphics, I have a profound appreciation for literature and history, particularly the works of Yasunari Kawabata, Orhan Pamuk, Jared Diamond, and Dafu Yu. During my undergraduate studies, I was selected for an honors program in the humanities and social sciences, where I took fascinating courses in aesthetic literature, world civilization history, Eastern and Western philosophy, and classical Chinese literature, achieving a ranking of 2 out of 46 in these courses.

I enjoy engaging with people to uncover and document their stories. So I interned as a journalist at Qianjiang Evening News, one of the leading news organizations in China, for six months. During my time there, I had the invaluable opportunity to publish over 20 news articles under the guidance of the Chief Reporter.

I also derive joy from painting, cooking, and 3D art creation. Here are some projects I worked on during my undergraduate studies.

I utilize Zbrush for character design, modeling, and coloring, while also employing skeleton binding to manipulate her posture.

We started with sketching the post-apocalyptic game scene design, utilizing Maya for modeling, Substance 3D Painter for creating texture maps, and Unreal Engine 4 for terrain modeling and rendering.

We designed and developed a game using the Unity framework. In this game, we started from scratch and accomplished a series of tasks, including scene construction, character modeling, character control, and animation implementation.
