HPG and EGSR 2010

Information on the 2010 iterations of the High Performance Graphics conference (HPG) and the Eurographics Symposium on Rendering (EGSR) is now available online.  The two conferences will be co-located in Saarbrucken, Germany in late June.  Fortunately (and unlike HPG’s co-location with SIGGRAPH this year) there is no overlap between the two – EGSR immediately follows HPG.  These are both excellent conferences with strong (albeit in HPG’s case, short) histories of high-quality real-time rendering work. For many of our European readers, the combination of the two conferences should prove irresistible.

Update: the HPG website and CFP are up.

Real-time Mandelbulb visualization with GigaVoxels

See this post on Cyril Crassin’s blog (I just saw it linked on Tim Farrar’s blog and had to mention it here since it is wicked awesome and I wouldn’t want anyone to miss it).

Cyril is the primary inventor of the Gigavoxels technique which has been the subject of several recent publications.  The Mandelbulb is similar to the Mandelbrot set, but in 3D.  Cyril evaluates the Mandelbulb on the fly to fill the brick cache used by the Gigavoxels.

Mandelbulb + Gigavoxels = real-time Mandelbulb visualization = pure win.

Rendering-related papers of the past 350 years

The Royal Society (full name: Royal Society of London for the Improvement of Natural Knowledge) is marking the start of its 350th year by putting pdf versions of 60 notable papers from its journal, Philosophical Transactions (founded in 1665) on the web.  Although all the selected papers are crucial to the history of science, I wanted to call out those particularly related to the fundamentals of rendering.

Almost all of Ke-Sen’s pages now up

Ke-Sen Huang has put up almost all the remaining pages that were taken down, after revising them according to ACM’s requirements:

The only pages not up yet are those for ACM’s Symposium on Solid and Physical Modeling (SPM) for the years 2005-2008.

More of Ke-Sen’s pages are back up (+ a new one)

Following the reinstatement of the SIGGRAPH 2009 page a few days ago, the following paper pages have been modified to the new ACM guidelines and are now back up:

This is a little less than half the pages that were taken down.

All this and Ke-Sen has also started to collect the Eurographics 2010 papers as well – the man’s a machine!

Ke-Sen Huang’s paper pages are down, will soon go back up

We have mentioned Ke-Sen Huang’s awesome paper preprint link pages in many previous posts – they’re the best graphics resource on the web by a long shot.

Early last week, many people (including myself) were shocked to see most of the pages replaced by the following:

REMOVED – This page has been removed at the request of the ACM Publications Board

This resulted in an outpouring of anger as well as support for Ke-Sen.  Many people in the community contacted the ACM Publications Board to try to convince them to change their position.

Fortunately, the story has a happy ending.  Today, Ke-Sen received the following email:

Dear Ke-Sen,

As you are aware, the computer graphics community has expressed dismay and concern about the removal of your web pages. ACM wants to make it possible for you to continue this service that the community clearly values very highly. By this message ACM grants permission for you to repost the pages, with the addition of links to the authoritative versions of the papers in the ACM Digital Library. The author’s home page links may also be included, but should not be links directly to the author’s version of the paper. Please post on the site that the information is being provided with the permission of the ACM. This is the solution you proposed earlier, and it is clear from the community’s comments that it is the right thing to do.

As you know, the concern about your pages was ACM copyright policy with regard to links. As a result of the community discussion, ACM will institute a formal review of this portion of its copyright policy.

Please contact us with any concerns or questions.

Sincerely,

Patricia Ryan
ACM Chief Operating Officer

ACM also offered to help with the work of adding the Digital Library links.  So nothing will be removed from Ke-Sen’s pages, and additional useful links will be added.

It will take a little while until the pages are back up, but they will be better than ever.  In the meantime, you can go to the Way Back Machine and find his pages from 2007 and earlier.

The graphics community has engaged with the ACM in a much more active manner than usual, which is a good thing.  We need to remember that it is our organization, and it is only as good as we make it.  So consider volunteering for conferences, paying more attention to ACM elections, etc. – I know I will.

DX9 GPU Hacks

When I transitioned from PC to console programming in 2003, I was struck by the many graphics hardware features I now had access to which are not supported by PC APIs such as Direct3D and OpenGL (the latter is in slightly better shape due to its support of vendor extensions).  Some of these features are supported by newer iterations of Direct3D, but for many people Direct3D9 is still the target of choice (it is the newest version supported on XP, and it most closely matches the capabilities of current-gen consoles).

Over the years, graphics hardware vendors have implemented an array of undocumented, semi-official hacks around the Direct3D9 API to allow access to more hardware features.  Aras Pranckevičius has recently put up a very useful list of these.  I have not seen this information anywhere else – kudos to Aras for doing the work.
