Multimedia Exposition

Multimedia presentations are sought for the 26th International Computational Geometry Multimedia Exposition (CG:MME), which will take place in July as part of Computational Geometry Week 2017. Computational Geometry Week also encompasses the 33rd International Symposium on Computational Geometry. The Multimedia Exposition showcases the use of visualisation in computational geometry for exposition and education, for visual exploration of geometry in research, and as an interface and a debugging tool in software development.

Content and Form

The content of multimedia presentations should be related to computational geometry or neighbouring areas, but is otherwise unrestricted. We encourage submissions that support papers submitted to the Symposium on Computational Geometry, but this is not required. In particular, results being presented are not required to be new. We explicitly encourage submissions that take new views on classic results from computational geometry, which may help to make such results more widely accessible.

The form of multimedia presentations can be anything other than the traditional paper or slide show. Algorithm animations, visual explanations of structural theorems, descriptions of applications of computational geometry, demonstrations of software systems, and games that illustrate concepts from computational geometry are all appropriate. There are no limitations on creativity, anything that leverages the possibilities of multimedia to enlighten and entertain the viewer while learning about computational geometry or neighbouring areas will do. This includes rendered animation, films with narrators and/or actors, and interactive stories, as well as interactive demos.

Quality Requirements

The “format” as well as the creative content of Multimedia submissions influences their acceptance. For videos, a length of three to five minutes is usually ideal; ten minutes is the upper limit. For the final version, we require video in 720p or better, using H.264. The embedded audio stream should be AAC of at least 128kBit/s. Telephone-sounding audio (limited frequency range, noise) or live rooms, as often recorded with cheap headsets, should be avoided, as well as speakers with too heavy accent.

Interactive applications (e.g., HTML5, Flash, AIR, Java, executable files, etc.) should provide a “demo” video demonstrating the functionalities of the software, for archiving on the website. These videos can be created with any screen recording software (such as CamStudio/VideoPad for Windows, QuickTime/iMovie for Mac, or Kazam/Kdenlive for GNU/Linux) together with voice description (by the authors or by a speech generator, such as eSpeak).

Multimedia submissions are limited to 100MB. Authors are free to post higher quality versions on their own web sites, and we will include links in the electronic proceedings to their version, in addition to the official (<100MB) version archived on www.computational-geometry.org.

It is strongly encouraged to contact the CG:MME program committee well in advance to 1) discuss the quality of a video submission (based on sample files) or 2) to present your non-video idea and how it could be reviewed, presented, and distributed.

Submission

Submissions should be deposited online where they are accessible through the web or via FTP. A video submission should play trouble-free on programs like VLC Media Player. For ease of sharing and viewing, we encourage (but do not require) that each video submission be uploaded to YouTube, and that the corresponding URL be included with the submission.

The application itself should be submitted with a small “how-to” use documentation in plain text. Ideally, the application should be universal (be able to run on any device and OS), but it is ok as long as it runs in reasonably common setups (for example, desktop computers with windows and Mac OS). We also recommend adding a “makefile” or a similar file to ease compilation.

Each submission should include a description of at most four pages of the material shown in the presentation, and where applicable, the techniques used in the implementation. This four-page description must be formatted according to the guidelines for the conference proceedings, using the LIPIcs format. LIPIcs typesetting instructions can be found at http://www.dagstuhl.de/en/publications/lipics and the lipics.cls LaTeX style file at http://drops.dagstuhl.de/styles/lipics/lipics-authors.tgz.

Send a mail to the CG:MM chair, Matias Korman (korman at nii.ac.jp) by March 10, 2017, with the following information:

  • the names and institutions of the authors
  • the email address of the corresponding author
  • instructions for downloading the submission
  • if available: the link to the YouTube video
  • and the PDF abstract.

We encourage multimedia submissions that support papers submitted to the Symposium. However, submitted papers and associated 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.
