My name is Linxuan (Peter) Rong. I am a PhD Student in Computer Science at Washington University in St. Louis, conducting research in Computer Graphics under the supervision of Prof. Tao Ju.
Previously, I attended high school at Western Reserve Academy and completed my undergraduate degree in Computer Science and Applied Mathematics from Washington University in St. Louis in May 2023.
In my spare time, I enjoy singing and music, casual ultimate frisbee, and board games.
📝 Publications
Persistence-guided Prescribed Topological Simplification
Linxuan Rong, Tao Ju
ACM Transactions on Graphics (Proc. ACM SIGGRAPH 2026)
A novel persistence-guided framework for topological simplification that prescribes the target topology exactly.
Our approach supports both cutting and filling operations to resolve unwanted topological features, and generalizes to arbitrary cell complex representations including tetrahedral meshes, cubical volume grids, and Voronoi cells.
