Welcome to my homepage. I'm currently a Post-doctoral Fellow in GameLAB, School of Computer Engineering(SCE), Nanyang Technological University(NTU) in Singapore. I received the M.S. and PhD degrees under my supervisor Prof. Wang Guojing in Computer Graphics from Zhejiang University(ZJU), and the B.S. degree in Applied Mathematics from China University of Mining and Technology. 

I am currently searching for a research scientist or a faculty position of universities around the world. If you are interested, I can be reached anytime via email at xinshiqing@gmail.com.

Academic Achievements

  • When I worked in Autodesk Shanghai from 2007 to 2009, I proposed an automatic algorithm for disassembling 3D products. The functionality becomes an important part of Autodesk Inventor Publisher (http://www.youtube.com/watch?v=Q98QsvIM1pg). The related research results were filed to the US patent office (Application No. PCT/CN2009/073694) on September 2, 2009.
  • I presented an exact geodesic algorithm in 2009 (published on ACM TOG 2009; presented at ACM SIGGRAPH 2010), which is widely accepted by the computer graphics community and still the best one for this problem.
  • I designed a new type of burr puzzles, which can be applied to any real-world models. The paper was presented at ACM SIGGRAPH 2011. At the same time, the research results were filed to the US patent office (NTU ref: PAT/081/11/11/US Prov; M&C ref: FP5544). And the representative figure was selected to appear on the back cover of the SIGGRAPH proceeding.
  • I proposed and implemented the first exact algorithm for computing geodesic loops that is even faster than previous approximation algorithms. The paper was published on IEEE TVCG 2011.
  • I proposed the first framework for supporting constant-time geodesic distance query. The paper was presented on ACM SIGGRAPH Symposium on I3D 2012.
  • During the past two years, I published at least 3 TOP journal/conference papers: 1 TOG paper, 1 SIGGRAPH paper, 1 ICDCS paper. Besides, 2 I3D papers, 1 TVCG paper, 1 MICCAI paper, 1 MobiHoc paper were accepted in the past two years.
