This just came in the mail from the program committee chair, David Kirkpatrick; the official version should be up on the

conference web site soon. Submissions are due

**December 2**, with abstract due one week in advance.

The program committee includes my ex-student Erin Chambers, my academic sibling Nina Amenta, Nina's and my PhD advisor Raimund Seidel, and Raimund's MS advisor David Kirkpatrick. It's like a family reunion! (I am so screwed.)

**26th Annual Symposium on Computational Geometry (SoCG 2010)**

June 13-16, 2010

Snowbird, Utah, USA

In cooperation with ACM SIGACT and SIGGRAPH

http://www.sci.utah.edu/socg2010/
The Twenty-sixth Annual Symposium on Computational Geometry will be held at Snowbird, Utah. We invite submissions of high-quality papers, videos, and multimedia presentations describing original research addressing computational problems in a geometric setting, in particular their algorithmic solutions, implementation issues, applications, and mathematical foundations.

The topics of the Symposium reflect the rich diversity of research interests in computational geometry. They are intended to highlight both the depth and scope of computational geometry, and to invite fruitful interactions with other disciplines. Topics of interest include, but are not limited to:

- design, analysis, and implementation of geometric algorithms and data structures; lower bounds on the computational complexity of geometric problems;
- mathematical, numerical, and algebraic issues arising in the formulation, analysis, implementation, and experimental evaluation of geometric algorithms and heuristics; discrete and combinatorial geometry; computational topology;
- novel algorithmic applications of geometry in computer graphics, geometric modeling, computer-aided design and manufacturing, scientific computing, geographic information systems, database systems, robotics, computational biology, machine learning, sensor networks, medical imaging, combinatorial optimization, statistical analysis, discrete differential geometry, theoretical computer science, graph drawing, pure mathematics, and other fields.

**CALL FOR PAPERS**
We invite submissions of high-quality papers describing original research on geometric algorithms and data structures, their mathematical foundations and correctness, their implementation, and their applications.

The program committee explicitly encourages the submission of video or multimedia in support of submitted papers. Authors may wish to consider making a separate submission to the video/multimedia track (see the guidelines below). Papers and video/multimedia submissions will be reviewed separately; acceptance or rejection of one will not influence acceptance or rejection of the other.

Final versions of accepted papers will be published by ACM in the symposium proceedings. Proceedings will be distributed to symposium participants and will also be available from ACM for purchase or through the digital library. An author of each accepted paper will be expected to attend the Symposium and give a presentation (approximately 20 minutes) of the paper. Authors of a selection of papers from the conference will be invited to submit extended versions of their papers to a special issue of one or more journals.

**Paper Submission**

All submissions should be made electronically; see the EasyChair SoCG2010 web pages
http://www.easychair.org/conferences/?conf=socg2010
for detailed submission instructions. If electronic submission is not feasible, please contact the program committee chair, David Kirkpatrick <socg-chair@cs.ubc.ca>, well in advance of the submission deadlines.

**Submission Guidelines**

Papers should be submitted in the form of an extended abstract, which begins with the title of the paper, each author's name, affiliation, and e-mail address. This should be followed by a precise statement of the problem considered, a succinct summary of the results obtained (emphasizing the significance, novelty, and potential impact of the research), and a clear comparison with related work. The remainder of the extended abstract should provide sufficient detail to allow the program committee to evaluate the validity, quality, and relevance of the contribution. Clarity of presentation is very important; the whole extended abstract should be written carefully, taking into consideration that it will be read and evaluated by both experts and non-experts, often under tight time constraints.

Submissions should be typeset in single column format, using 11-point or larger font, with at least 1 inch/2.54 cm margins and single line spacing. Excluding the title page and bibliography, the extended abstract must not exceed 10 pages. Submissions deviating from these guidelines risk rejection without consideration of their merits.

A clearly marked appendix (of reasonable length) containing additional technical details may be included directly in the submission. Other supporting materials, such as an expanded version of the paper, a video or multimedia presentation, source code, or experimental data, may be provided by including a URL in the submission. Appendices and other supporting materials will not be regarded as part of the actual submission and will be considered only at the discretion of the program committee.

Authors must submit the title and a short abstract of their paper by November 23, 2009. This pre-submission will be used to help make program committee reading assignments. Extended abstracts must be received by **December 2, 2009** (23:59, Honolulu time). There will be no extension of this deadline; late submissions will not be considered.
Authors will be notified of acceptance or rejection by February 15, 2010. Final versions of accepted submissions will be due by March 15, 2010 for inclusion in the proceedings. The final proceedings papers must be formatted in accordance with ACM proceedings guidelines; LaTeX style files will be made available to authors of accepted papers.

Concurrent submission of the same (or essentially the same) abstract to SoCG and to another conference with published proceedings is not allowed. An extended abstract of a paper that is under journal review, or scheduled for publication in a journal after June 2010, may be submitted, when it is clear that the extended abstract differs substantially from the journal version. In such cases, the authors must include the journal version in an appendix that clearly identifies the status of the journal submission.

**CALL FOR VIDEO AND MULTIMEDIA PRESENTATIONS
**

19th Annual Video/Multimedia Review of Computational Geometry

Video and multimedia presentations are sought for the 19th Annual Video and Multimedia Review of Computational Geometry. This review showcases the use of visualization in computational geometry for exposition and education, for the visual exploration of geometry in research, and as an interface and a debugging tool in software development. Algorithm animations, visual explanations of structural theorems, descriptions of applications of computational geometry, and demonstrations of software systems are all appropriate.

Three to five minutes is ideal for most animations and presentations of applications; eight minutes is the upper limit. Submissions of movie clips in QuickTime or MPEG-4 compressed formats (e.g., XviD or DivX version 6) are encouraged. For ease of sharing and viewing, we encourage (but it is not required) that each submission be uploaded to YouTube, and that the corresponding url be supplied along with the submission. Consider adding a subtitle track to movie clips. We also encourage submissions of Macromedia Flash, Java applets, and limited forms of other multimedia or software. These formats must come with a script that will allow them to be distributed in both interactive and canned QT or MPEG movie formats. In case of doubt, please email the Video and Multimedia Program chair. Some suggestions on making movie clips can be found at
http://www.ams.sunysb.edu/~jsbm/SoCG10/video_suggestions.html.

Accepted video and multimedia presentations will have an abstract in the published conference proceedings; video/multimedia authors will have an opportunity to present their work at the conference during a dedicated video session. Accepted presentations will be available online in various formats in a web proceedings. (The 2009 video proceedings are available at
http://www.computational-geometry.org/SoCG-videos/socg09video/.)

**Video/Multimedia Submission**

Video/multimedia submissions should be sent by e-mail to the Video/Multimedia committee chair, Joe Mitchell <mitchell@compgeom.com>, to arrive by 23:59, New York time, Friday, February 19, 2010.

The author(s) should submit a one or two-page description of the material shown in the presentation, and where applicable, the techniques used in the implementation. An email address of the corresponding author and a URL or ftp address where the supporting materials can be retrieved must be included. The final two-page descriptions must be formatted according to the guidelines for ACM proceedings; LaTeX style files will be provided to authors of accepted presentations.

We explicitly encourage video/multimedia submissions that support papers submitted to the symposium. Submitted papers and associated video/multimedia submissions will be treated entirely separately by the respective committees: acceptance or rejection of one will not influence acceptance or rejection of the other.

Authors will be notified of acceptance or rejection, and given reviewers' comments by March 1, 2010. For each accepted submission, the final version of the 2-page textual description will be due by March 15, 2010 (electronically) for inclusion in the proceedings. Final versions of accepted video/multimedia presentations will be due April 20, 2010 in the best format available.
