- June 27, 2011:
Our VASE (volume-aware surface evolution) paper has been accepted to
SGP 2011. Congrats to
- June 22, 2011:
Slides for SMI 2011 talk on point cloud silhouettes is
available. In retrospect, the paper is really about how to find proper k-nearest neighbors (kNNs)!
- April 7, 2011:
Helmut Pottmann gives
a Distinguished Lecture on Geometric Computing for Freeform Architecture.
- April 6, 2011:
successfully defended his Ph.D. thesis on "A Plane View of Geometric
Silhouettes". Congrats, Matt!
- March 30, 2011: Congrats to
who is awarded an Alexander Bell Canada Graduate Scholarship from NSERC;
the award is given to the most selective group of scholarship
- February 11, 2011:
Congrats to Ibraheem
who successfully defended his MSc thesis on detail-replicating shape
stretching; see demo
video and code.
- December 4, 2010:
Upcoming talk by Steven (Shlomo) Gortler
on December 17. See talk
- November 10, 2010:
Upcoming talk by Ligang Liu who will be visiting me between Nov. 21 and 24. See
- September 13, 2010:
Final version of our three SIGGRAPH Asia papers are now available:
1. cone carving;
2. tree skeleton reconstruction;
3. style-content separation.
- August 20, 2010:
Visit from Johannes Kopf
(Microsoft Research) and Dani
University) and talk by Johannes on Street Slide and Automatic Generation
of Destination Maps.
- July 26, 2010: Our
on spectral mesh processing has concluded. See this
wiki from ALICEpedia for all the course-related information,
including presentation slides. A previous version of the
course was given at SIGGRAPH Asia 2009.
- May 12, 2010: Slides for my Eurographics 2010
Report (STAR) talk on shape correspondence is available here.
- April 30, 2010: Andrea
Tagliassachi has received the MITACS Best
Student Paper Award for 2009. Congrats, Andrea!
- January 12, 2010: One
of our papers won the 2010 Most Cited Paper Award for
the journal Computer-Aided Design.
Papers for this distinction are determined solely based on the highest number
of cites, excluding self-citations, received for all journal articles published in
- November 16, 2009: Due to popular demand, we are making the MATLAB code for
our earlier paper on
robust spectral shape correspondence available. Please download
this ZIP file. The code can be easily adapted to compute
the eigenvalue shape descriptors (EVD) from this paper. Instructions are
in the README file. Note that this code does not contain a Nystrom approximation component,
hence only somewhat small meshes (up to 5K vertices) should be tried on. The code was
written by Varun Jain and last updated by Oliver van Kaick. If you have
any questions, please ask Oliver or myself.
