New Open-Access Computer Graphics Journal

After talking about open access so much, it feels great to finally be doing something about it! Eric and I are both on the founding editorial board for the Journal of Computer Graphics Techniques (JCGT), a new peer-reviewed computer graphics journal which is open access, has no author fees, and is practice-focused (in the spirit of the Journal of Graphics Tools).

Similar to other journal “declarations of independence”, the JCGT was founded by the resigning editorial board of the Journal of Graphics Tools (JGT). Initially created as a “spiritual successor” to the Graphics Gems series of books, JGT had a unique focus on practical graphics techniques and insights, which is being continued at JCGT.

With Morgan McGuire (the editor-in-chief) and the rest of the editorial board, we plan to leverage this illustrious history, our expertise, and the advantages of online self-publishing and open access to create a truly exceptional journal. But we need your help. Like any journal, JCGT can only be as good as the papers submitted to it.

If you are a researcher, we hope the pedigree of the editorial board, the increase in impact afforded by open access, the lack of author fees, and the streamlined process will make JCGT compelling to you as a publication venue.

We also want to reach out to industry practitioners (especially game developers) who would not typically consider publication in a peer-reviewed journal. Similarly to its predecessor, JCGT emphasizes practicality and reproducibility over novelty and theory, and the papers differ from the typical “research paper” style (lengthy “related work”, “conclusion” or “future work” sections are not required). There are also many advantages to publishing in JCGT vs. more traditional industry channels such as trade conferences, magazines, books, and blog posts. The open access format guarantees wide and immediate distribution, and the peer-review process will provide valuable insights and comments on your work from some of the top experts in the field as well as assure potential readers of the high quality of the work.

Open access to research: an idea whose time has come. Be a part of it!

How to Submit SIGGRAPH Talks or Dailies at the Last Minute

UPDATE: The Dailies deadline has been pushed back to May 21st.

The last deadline for submitting SIGGRAPH Talks and Dailies is on May 1st, in just two days (the exact deadline is 22:00 UTC/GMT on May 1st – you can use this website to find out what time that is where you are).

That doesn’t leave much time at all. However a submission to either program can be done quickly, and I’m going to detail the exact steps needed. I’ll list Talks and Dailies separately, since each of these programs not only has a different submission procedure but is relevant to a different audience (Talks are typically presented by graphics programmers and tech artists; Dailies by production artists). This post in general is geared towards game developers rather than researchers, so I’m talking about Word rather than LaTeX, etc.

Last-Minute Talks Submission Process:

  1. Decide what you are going to talk about. Note that SIGGRAPH Talks are only 20 minutes long, and can cover a variety of topics. Some example Talk abstracts are linked at the end of a previous post; the guidelines under “Production Talks” in the Talks page “Evaluation” tab can also be useful. In general if you recently did anything technically cool related to graphics (rendering feature, art tool, asset creation workflow, etc.), it might be a good Talk topic.
  2. Make sure you have any needed permissions from your boss / employer / etc. to submit the Talk.
  3. Write a one-page abstract using this Word template – the links from the first step can also be useful for seeing how to boil down your presentation into a one-page description that will resonate with the jury. Make sure the abstract is only one page long, has at least one image, and clearly describes the specific innovations you will talk about. Save out a PDF file.
  4. If your Talk topic has a dynamic component to it (e.g. it’s about animation, simulation, or anything else that can’t be judged via still images alone), capture a small amount of video to upload with your submission; a few seconds to a minute are enough in most cases. The video must be in QuickTime MPEG-4 or DivX Version 6 formats, and the file size should not exceed 100 MB (smaller is better for ease of uploading – try to keep the file small by reducing resolution and increasing compression  – not too much or it will be hard to see the visual quality of your results).
  5. Create an account in the SIGGRAPH Information System (just log in if you already have an SIS account). Click on this link, fill in the items marked in bold red, and click the “Create My Account” button at the bottom. An email will be sent to the address you provided – make sure it wasn’t caught in a SPAM filter (it will arrive from sis_support@siggraph.org) and use the provided temporary password to log in. Check the “Change Password” checkbox, type in your temporary and new passwords and click the “Save” button and subsequent “OK” button.
  6. Click on “Begin a New Submission”. You may be asked to verify your account details – if this happens look them over, make any needed changes, click the “Save These Changes” button at the bottom, and click “Begin a New Submission” again.
  7. Look for the “Late Breaking” submission type, and click the “Create” button on that row.
  8. Copy-paste some appropriate text from the one-page abstract you previously wrote to fill in the “Title”, “Summary Statement” and “Short overview” sections. Select a few appropriate keywords and a primary jury  category (most likely “Behind the Scenes”, “Best Practices”, or “Methods and Systems”) from the drop-down lists provided. If you’ve previously presented the work elsewhere (e.g. GDC), check the appropriate checkbox and provide details. If the material you are uploading now differs in some significant way from the final presentation (e.g. you are using test assets now and will show final game assets at SIGGRAPH), check the appropriate checkbox and provide details. Ignore the “English Review Service” checkbox – there won’t be time to make use of that service; if you’re not fluent in English, ask a friend or colleague who is to help look over your submission. Don’t worry about the two Education Resources checkboxes either. Click the “Next>>>” button at the bottom of the page.
  9. Select “Yes” for “I have the necessary rights, permissions, and/or licenses…” (make sure you are indeed not uploading anything you don’t have the rights for – as long as its all from your work and your employer is OK with it you should be fine). In most cases you will select “No” for “My material contains audio” unless you are planning to upload video with an audio track (which you typically won’t need to do). If there is audio make sure it isn’t something like a song you don’t have permissions for (if this is in-game audio and your employer approves, you are likely OK here).
  10. You won’t have time now to ensure your employer is OK with all the various permissions, so just click “Deny” on the “To grant or deny all of the following rights to SIGGRAPH 2012…” option. Plan to talk to your employer after the deadline and try to get permission to grant as many of these as possible – if your submission is accepted you will be able to modify the permissions later (make sure you do!), and if it isn’t it won’t matter. Enter your full name in “By entering my full name…” on the bottom of the page and click “Next>>>”.
  11. On the “Add Presentation Formats” page, click the “Create->” button for the “Talk” format.
  12. Choose “20 minutes” for the length of your talk – it’s hard to get longer talks accepted and most topics of interest can be squeezed into 20 minutes. Click “Eligible for Studio Talk” if your talk has anything to do with asset or level creation, especially if there is a user-generated content aspect. Click “Next>>>”.
  13. Use the next page to upload the one-page PDF abstract you previously created. Also upload a “representative image” (typically the same image you used for one of the abstract figures, in JPEG format), and any video you have captured previously. Click “Next>>>”.
  14. Use the next page to add any co-authors. You can also add them later if the Talk is accepted, so if you don’t have time to do so now it’s OK. Click “Next>>>”.
  15. You are now done; you can still log in again any time before the deadline to tweak your submission if you want. Good luck!

Last-Minute Dailies Submission Process:

  1. Decide which of your work you will show. Dailies presentations are extremely short (about 2 minutes); they are intended to showcase a single bit of high-quality production art (animation, model, sequence, rig, effect, shader, etc.). There should also be an interesting backstory of some kind (an impossible deadline, a late-night inspiration, an artistic argument, an unexpected romance, etc). This example Dailies presentation and lists of accepted Dailies from SIGGRAPH 2010 and from SIGGRAPH 2011 might help in picking the right piece.
  2. Make sure you have any needed permissions from your boss / employer / etc. to submit the artwork.
  3. Write up the backstory of working on the piece. Did you have to work under a completely unreasonable deadline? Did you end up doing the exact opposite of what the art director said she wanted and she loved the results anyway? Did your life experiences inform the work (e.g. a background in breakdancing influencing a combat animation)? This should be an amount of text you can read onstage in less than two minutes, while video of your artwork plays behind you. Save out a PDF file of your backstory from Word, Google Docs etc.
  4. Capture a video (no more than 90 seconds long) which shows your work; this would be something like a model turntable, looping animation, progression sequence, etc. The submitted video needs to be QuickTime, H264 encoded, 640 x 360p, up to 90 seconds, no sound. This low-res video is just for reviewing purposes; upon acceptance you will need to submit a 720p video.
  5. Create an account in the SIGGRAPH Information System (just log in if you already have an SIS account). Click on this link, fill in the items marked in bold red, and click the “Create My Account” button at the bottom. An email will be sent to the address you provided – make sure it wasn’t caught in a SPAM filter (it will arrive from sis_support@siggraph.org) and use the provided temporary password to log in. Check the “Change Password” checkbox, type in your temporary and new passwords and click the “Save” button and subsequent “OK” button.
  6. Click on “Begin a New Submission”. You may be asked to verify your account details – if this happens look them over, make any needed changes, click the “Save These Changes” button at the bottom, and click “Begin a New Submission” again.
  7. Look for the “SIGGRAPH Dailies” submission type, and click the “Create” button on that row.
  8. Enter a title for your submission, as well as a one-sentence summary of the art piece and a slightly longer (2-3 sentences) overview explaining the key points (why it is good/interesting/etc.). Don’t worry about the Education Resources checkboxes at this point. Click the “Next>>>” button at the bottom of the page.
  9. Select “Yes” for “I have the necessary rights, permissions, and/or licenses…” (make sure you are indeed not uploading anything you don’t have the rights for – as long as its all from your work and your employer is OK with it you should be fine). Select “No” for “My material contains audio” (your captured video should not have an audio track).
  10. You won’t have time now to ensure your employer is OK with all the various permissions, so just click “Deny” on the “To grant or deny all of the following rights to SIGGRAPH 2012…” option. Plan to talk to your employer after the deadline and try to get permission to grant as many of these as possible – if your submission is accepted you will be able to modify the permissions later (make sure you do!), and if it isn’t it won’t matter. Enter your full name in “By entering my full name…” on the bottom of the page and click “Next>>>”.
  11. Use the next page to upload the PDF backstory you previously created. Also upload a “representative image” (just a frame from your captured video, in JPEG format), and the video itself. Click “Next>>>”.
  12. If your piece has any co-authors (most Dailies just have one author, but there might be someone else you want to also credit on the piece) use the next page to add them. You can also add them after acceptance, so if you don’t have time to do so now it’s OK. Click “Next>>>”.
  13. You are now done; you can still log in again any time before the deadline to tweak your submission if you want. Good luck!

Author-Izer, and what do publishers provide

There’s a new service provided by ACM’s Digital Library: Author-Izer. Short version: if you have published something with the ACM, and you have a preprint of the paper on your own or your company’s website, you can provide the ACM DL this link for your article and they’ll put it with the article reference. This is fairly sporting of the ACM. If you’re an author it’s worth this bit of effort to give your work wider dissemination. Linking also can provide the ACM with download statistics from your site and so give a better sense of the impact of your paper (or at least inflate your statistics compared to people not using Author-Izer).

As a reader without an ACM DL subscription, it’s still better to go to Ke-Sen Huang’s site or Google Scholar, where these external author sites have been collected without each author’s effort. For example, free preprints of 95% of SIGGRAPH 2011 papers are linked on Ke-Sen’s page. In a perfect world, the ACM would simply hire Ke-Sen for a few days and have him add all his external links of authors’ sites to their database. I’d personally toss in $20 towards that effort. I suspect there are 18 reasons given why this would not be OK – “we want individual authors to control their links” (but why not give a default link if the author has not provided one?), “we’re not comfortable having a third party provide this information” (so it’s better to have no information than potentially incorrect information leading you, at worst, to a dead link?), or the catch-all “that’s not how we do things” (clearly).

As Bernie Rous discusses, there’s a tension at the ACM between researchers, who want the widest dissemination of their work, and professional staff, who are concerned about the financial health of the organization. Author-Izer helps researchers, but there’s little direct benefit to the ACM’s bottom line. Unfortunately, currently the Author-Izer service seems to be virtually unknown. For example, the SIGGRAPH 2011 table of contents appears to have no Author-Izer links, though perhaps I’m missing them. I hope this post will help publicize this service a bit.

It’s nice that the ACM allows authors to self-archive, where they can provide preprints of their own work on their website or their institution’s. Most scholarly journals allow this archiving of preprints – more than 90%, according to one writer (and more that 60% allow self-archiving of the refereed final draft, which the ACM does not allow). For authors at academic institutions with such archives, great, easily done; for authors at games companies, film companies, self-employed, etc., it’s catch-as-catch-can. If the author hosts his own work and is hit by a meteor, or just loses interest, his website eventually fades away and the article is then available only behind a paywall. One understandable reason for ACM’s “must be hosted by the author or his institution” clause is that it disallows lower-cost paywalls from competing. But why not just specify that? I can see a non-compete clause like “the author will not host his preprint behind a paywall” (a restriction the ACM doesn’t currently have), but otherwise who cares where the article is hosted, as long as it’s free to download?

This restriction feels like a business model founded on being a PITA: instead of uploading his article to some central free access site and never thinking about it again, each author needs to keep track of access and deal with job changes, server reorganizations and redirects, company bankruptcy or purchase, Author-Izer updates, and anything else that can make his website go off the radar. Pose this problem to a thousand authors and the free system will be inherently weak and ineffectual, making the pay version more desirable.

I believe that many people in the ACM have their hearts in the right place, there’s no conspiracy here. However, the tension of running a paywall service like the Digital Library gives a “one hand tied behind my back” feel to efforts at more open access. If there were no economic constraints, clearly the ACM DL would be free and there would be no real point to Author-Izer. Right now there still are these financial concerns, very real ones.

A journal publisher used to offer:

  • Physical journal printing and binding
  • Copy editing, illustrations, and layout
  • Peer review and professional editors
  • Archiving
  • Distribution to subscribers and institutions
  • Reputation

The physical artifact of the journal itself is becoming rarer, and authors now do copy editing, illustrations, and most to all of the layout. The technical editors and reviewers are all unpaid, so their contributions are separate from the publisher itself – many journals have abandoned their publishers, as the recent Elsevier boycott has highlighted. So what is left that publishers provide?

Another way to look at it: what if publishers suddenly disappeared? Different systems would supplant their services, for good or ill: Google, for instance, might provide archiving for free (they already do this for magazines like Popular Science). Distribution is as simple as “get on the mailing list.” Reputation is probably the one with most long-term value. I don’t think I’d instead want to have a reddit up/down vote system, given the various problems it has. CiteSeer and Google Scholar are pretty good at determining reputation by citation count. You can even check your own citation count for free. There are ways of determining a paper’s impact beyond simple citation counts, lots of people think about this.

I can imagine a few answers for why publishers matter – these disconnected solutions I mentioned are not necessarily the best answers. However, the burden of proof is on the publisher, both commercial and non-profit, to justify its continued existence. It will be interesting how the various open access initiatives play out and how they affect publishers.

Only Four Days for SIGGRAPH 2012 Real-Time Live Submissions

One of the best SIGGRAPH venues for showing off real-time rendering applications, Real-Time Live, has a deadline on April 9th – just four days away.

SIGGRAPH Real-Time Live is a showcase of the very best real-time graphics of the year, running live before a large audience of the world’s top graphics researchers and practitioners.

Presentations are about 5-10 minutes long, and typically involve one presenter running the application while another discusses some key technical features. The trailer can give an idea as to what these presentations are like. Previous year’s Real-Time Live presentations have included games such as “God of War III”, “Fight Night”, and “Blur”, graphics demos from GPU & engine vendors as well as the demoscene, and other cutting-edge examples of the best of real-time graphics – scientific visualization, medical imaging, you name it.

The deadline is only 3-4 days away, but fortunately submission to the program is easy, requiring only five minutes of footage and filling out some web forms. If you’ve worked on any kind of real-time graphics application, you may want to consider submitting it to this unique program.

SIGGRAPH 2012 Hotel Registration Open

Go get your hotel reservation for SIGGRAPH 2012 now. Reservations can be cancelled with no cost up to July 19th, so if you think there’s the slightest chance you’ll go, grab a room now.

The HQ hotel and the Figueroa are already gone. The Ritz Milner is certainly cheap and pretty close, but some TripAdvisor reviews eventually scared me off. I then switched to the Luxe City Center (used to be a Holiday Inn), as I prefer being close to the convention center. But I recall complaints about things like the WIFI stinking at the old Holiday Inn, and the place is even pricier now. So I rebooked yet again into The Sheraton, as a pretty good compromise among the factors of cost, quality, and location – being more downtown can be good, as you’re closer to restaurants and other nighttime activities.

English Translations of tri-Ace CEDEC 2011 Slides Available

Yoshiharu Gotanda, the CEO and CTO of tri-Ace, has given many excellent graphics presentations over the years, mostly focused on physically based real-time rendering. Gotanda-san’s presentations are hosted on the tri-Ace research webpage. Some of these were originally given in English; these include presentations at  GDC 2005, 2009 and 2012, as well as SIGGRAPH 2010 courses on shading (slides, course notes) and color (slides, course notes). However, many of Gotanda-san’s presentations were given in Japanese at the CEDEC conference, and the slides are also in Japanese.

Fortunately, the slides for two of these presentations (from CEDEC 2011) have been translated into English, in a collaboration between Gotanda-san and Marc Heng (Square Enix Japan). In addition, reviews of the English version were performed by Sébastien Lagarde (DONTNOD Entertainment) and myself. These presentations deal with the theory and implementation of physically based rendering used in the tri-Ace 2011 demo trailer, as well as forthcoming titles. Both presentations are highly recommended.

Hopefully in the future, other good CEDEC graphics presentations by Gotanda-san and others (e.g. Masaki Kawase) will be translated into English.

1200 Books You May Have Rented

If you’re a member of ACM, you have access to about 1200 books online through Safari and Books24x7. Safari’s catalog is here, Books24x7 is here. Just login using your ACM ID & password. I can’t say the book selection is that exciting, some are half a decade old or older (bad for books about APIs), though there are few that might be of interest. If nothing else, there are some guides to popular packages and languages that might help you out.

Worth a reminder: if you’re an ACM SIGGRAPH member, you also get access to essentially all computer graphics papers in the ACM’s Digital Library. I took a peek today to see if the I3D 2012 papers were up yet (the conference runs this weekend) – no joy there, though 2011’s are available. At least, I’m pretty sure 2012’s are not up. Personally, I find their searcher kind of poor if you want to search through proceedings, but is otherwise serviceable for individual articles. As usual, Ke Sen Huang’s page is the place to go to get most of the latest articles (with no membership needed).

Oh, just to reel off some other free books that might be of interest: Autodesk’s “Imagine Design Create” book, a free PDF. More for designers but full of pretty pictures and there’s stuff on game graphic design, along with films and much else. If you’d rather have the coffee-table version, get it on Amazon.

Me, I just finished the crowd-sourced sci-fi “Machine of Death” compilation, which has nothing to do with computer graphics but was an interesting bedtime read. Free as an ebook or audiobook, or again in physical form from Amazon.

I3D Game Industry Day

Any Southern California game industry graphics people who weren’t planning to attend I3D this year might want to reconsider; there is a great deal on registration prices for the last day (this Sunday). Sunday has been packed with the most highly relevant content for game developers (though there is some great stuff in the previous two days as well), and there is a special one-day registration price of $125. This sum gets you a panel on sharing technical ideas in the games industry (moderated by Marc Olano – the panelists are Mike Acton, Mark DeLoura, Stephen Hill, Peter-Pike Sloan, Natalya Tatarchuk, and myself), as well as three paper sessions. These sessions include the following papers:

Besides the technical sessions, I3D is a great opportunity to meet and talk to some of the top experts in real-time graphics; if you’re local and not already planning to attend, I warmly recommend it.
