Formats

Authors are required to submit fully formatted papers, with graphs, images, and other special areas arranged as intended for final publication using the ACM SIGGRAPH paper preparation guidelines. Be sure that all pages are numbered and that the first page contains your paper's ID number, in the place where authors' names normally go (below the paper title).

For SIGGRAPH 2007, authors must submit their papers electronically. The only allowable format is Adobe PDF. We encourage authors to send supplemental materials (anything except the paper) electronically if possible, but we will accept physical submission of these materials. See Detailed Instructions and Checklist for more information. For electronically submitted videos, we strongly encourage QuickTime MPEG-4 or DivX Version 6, and for still images, we strongly encourage TIFF, JPG, or PNG. If you use another format, you are not guaranteed that reviewers can view them. In preparing videos, please choose a reasonable frame size and rate. If your supplemental materials amount to more than 100 Mbytes of data, you are not guaranteed that reviewers can download and view them. In that case, you should consider using the physical submission process for these materials. (Your paper must still be submitted electronically.)

Anonymity

Remove any information from your submission materials (paper, video, images, etc.) that identifies you or any of the other authors, or any of your institutions or places of work. If you are a well-known author, don't narrate your video; get someone else to do it. You must reference all relevant work completely, however, including your own and that of the other authors. In the paper, refer to your own published or otherwise widely known work, and to that of the other authors, in the third person (for example: his work, her work, their work). Reference as "anonymous" only work that you or the other authors have submitted for publication, but that has not yet been published.

Do not include URLs referring to web sites that contain vital material for your submission. Such material won't be considered, since reviewers cannot access it without endangering the anonymity of the reviewing process.

Please keep the PDF version anonymous; in particular, note that under some operating systems the "properties" of a PDF file may contain the creator's name. Also, Version 7 PDF files allow inclusion of a script that will contact the author each time the file is opened. Do not include this script in your PDF file; if we find it, we will reject your paper without review.

Public dissemination of submitted papers, whether by posting them online or by delivering them as talks, is strongly discouraged, in so far as it may destroy your anonymity. However, we recognize that PhD students looking for jobs must give job talks, and they often wish to include their submitted papers on their web pages. We also recognize that laboratories looking for funding need to publicize their latest research. Therefore, we merely ask that authors use restraint whenever possible. Be aware that reviewers are human, and they may become annoyed if they see blatant or unjustified violations of anonymity.

To reiterate the main point, do not include author names or affiliations anywhere within your submitted paper or supplemental materials. For more information, see the Anonymity section of Frequently Asked Questions.

Paper Length

There is no arbitrary maximum length imposed on papers. However, reviewers will be instructed to weigh the contribution of a paper relative to its length. For example, a useful idea presented completely in four pages is more likely to be accepted than the same idea presented in eight pages. Papers longer than 8-10 pages must make a very significant contribution to be accepted. Papers of four or fewer pages will be held to a less strict standard of citation and description of related work. Comparison to the strongest alternative techniques is still important, but an exhaustive review is not necessary. You must declare the page length of your paper on the Papers Submission Form when you submit your abstract. You may change this length as often as you like until the paper submission deadline (24 hours later). The page length need not be an even number.

Once the paper submission deadline has passed, it is expected that if your paper is accepted, its final length will be equal to the length you have entered. If you wish to substantially change this length during the revision cycle, or if you wish to add any pages to the length of your paper, you must first obtain permission from your referee.

Companion Videos

Papers may be accompanied by a video that is five minutes or less in length. In recent years, well over half of the accepted papers were accompanied by some kind of video material. To the extent possible, accepted papers should stand on their own, with the video providing supplementary information or confirmation of results. However, it is fine to refer to the video in the paper. Video should not be included in a submission unless substantively similar footage can appear in the SIGGRAPH 2007 Full Conference DVD-ROM. If your paper is accepted and you cannot comply with this requirement, your acceptance will be rescinded.

Supplemental Materials

Authors are invited, but not required, to include supplemental materials such as images, additional videos, related papers, previous SIGGRAPH reviews, etc. These materials do not form a part of the official submission and will be viewed only at the discretion of the reviewers. These materials should be anonymized if possible. Anonymous materials can be made available to all reviewers; materials whose authorship can be readily ascertained will be seen only by members of the Papers Committee. If you send non-anonymous supplemental materials, please also send a cover letter indicating which material is non-anonymous, and explaining why you are sending it. There will be separate areas in the online submission form for submitting anonymized versus non-anonymized materials.

If you have a related paper that is under review or in press elsewhere, we strongly recommend that you send a version of this paper as supplemental submission material. Because we check with other conferences and journals for duplicate submissions (which are summarily rejected), you may also wish to include a cover letter that outlines the differences between your SIGGRAPH 2007 submission and the related paper. Related papers and cover letters need not be anonymous, as they will be used only by the members of the Papers Committee to determine whether the submitted work is unique. For more information, see the Double Submissions section of Frequently Asked Questions.

If your paper is a revision of a paper that has previously been submitted to a SIGGRAPH conference, we recommend that you include copies of the reviews that it received, and of your responses to them. Only the members of the Papers Committee will see these earlier reviews and comments. Note that simply responding to all earlier criticisms will not guarantee acceptance. It is not necessary to identify a paper as a revision of a previous submission, however.

If your submission is accepted, you will be asked to provide a signed ACM Copyright Form, which is required by ACM before your paper can be published. The form must be downloaded, printed, completed, signed, and faxed to the ACM SIGGRAPH Director for Publications.

In addition, an Acceptance Agreement will be produced from the Permissions section of your online submission form. You must print that agreement, sign it, and fax it or send it via postal or courier service before SIGGRAPH 2007. If we do not receive your completed, signed Acceptance Agreement, your work cannot be presented at SIGGRAPH 2007.
