Hi, there!

I‘m Rui Xu(徐瑞), a final-year master student at the Interdisciplinary Research Center (IRC) of Shandong University, under the tutelage of Prof. Changhe Tu , Prof. Shiqing Xin and Prof. Mingyan Jiang. My research interests are computer graphics, computational geometry, point cloud reconstruction and geometric modeling. Currently, I am interning at Microsoft Research Asia (MSRA). And I am joining The University of Hong Kong as a Ph.D. student supervised by Prof. Wenping Wang and Prof. Taku Komura.
