September 2009

You are currently browsing the monthly archive for September 2009.

The incomparable Ke-Sen Huang has put up yet another graphics conference papers page, this time for Pacific Graphics 2009.  The full papers list is up and there is a good number of preprints linked.  Pacific Graphics has had a good number of interesting papers over the years; this year continues the tradition.  HPCCD: Hybrid Parallel Continuous Collision Detection proposes an interesting combined CPU-GPU collision detection algorithm.  Procedural Generation of Rock Piles using Aperiodic Tiling uses an aperiodic tiling method (similar to a 3D version of Wang Tiles) to enable the quick placement of large numbers of random-seeming rocks.  The technique described in Fast, Sub-pixel Antialiased Shadow Maps is quite expensive (it improves quality and adds cost to  the already-costly irregular z-buffer technique), but it is worth looking at for applications running on advanced hardware (in other words, not for current-gen games platforms).  Finally, Interactive Rendering of Interior Scenes with Dynamic Environmental Illumination presents a PRT-like approach to render complex interiors lit by arbitrary environmental lighting coming in through windows.

Three more papers lack online preprints or abstracts (at the moment) but have promising titles: Procedural Synthesis using Vortex Particle Method for Fluid Simulation, Linkless Octree Using Multi-Level Perfect Hashing, and The Dual-microfacet Model for Capturing Thin Transparent Slabs.


SOMA Media has been providing (for a fee) video of SIGGRAPH presentations for the last few years; this service (SIGGRAPH Encore) is invaluable for people who could not attend the conference. Even if you did attend, it is great to be able to see presentations you had to miss (SIGGRAPH has a lot of overlap), or even to revisit presentations you were able to see.  The videos include the speaker’s voice synchronized with their screen feed, including slides as well as any demos they were showing – it is almost as good as being in the room.

Encore has part of SIGGRAPH 2003, as well as most of 2004, 2005, 2007 and 2008 (I’m not sure what happened to 2006).  As of yesterday, SIGGRAPH 2009 is available as well.  This includes Courses, Talks, and Computer Animation Festival presentations, as well as Technical, Game and Art Paper presentations.  However, not all sessions are available; as in previous years, some needed to be removed for copyright or other reasons.  Unfortunately, some of the omissions include key content like the Beyond Programmable Shading course and the second half of the Advances in Real-Time Rendering in 3D Graphics and Games course.  I will list the available presentations; if you see stuff you like, it might be worth purchasing the relevant presentation videos.  Individual videos cost between $10 and $20; the entire 2009 set is $300.  Presentations which I think are most relevant to readers of this site will be marked in bold.

The available courses are: “The Whys, How Tos, and Pitfalls of User Studies“, Introduction to Computer Graphics, Advances in Real-Time Rendering in 3D Graphics and Games I, Point Based Graphics – State of the Art and Recent Advances, Color Imaging, Real-Time Global Illumination for Dynamic Scenes, Acquisition of Optically Complex Objects and Phenomena, Creating New Interfaces for Musical Expression, An Introduction to Shader-Based OpenGL Programming, Next Billion Cameras, Advanced Illumination Techniques for GPU Volume Raycasting, Scattering, Visual Algorithms in Post-Production, Interaction: Interfaces, Algorithms, and Applications, Shape Grammars, and The Making of ‘Shade Recovered’: Networked Senses at Play.

With Wolfgang Engel’s blessing, I’ve added the ShaderX2 books’ (both of them) CD-ROM code samples as zip files and put links in the ShaderX guide. The code is hardly bleeding edge at this point, of course, but code doesn’t rot – there are many bits that are still useful. I’ve also folded in most of the code addenda into the distributions themselves. The only exception at this point is Thomas Rued’s stereographic rendering shaders; in reality, more up-to-date information (and SDK) is available from the company he works with, ColorCode 3-D.

A professor contacted us about whether we had digital copies of our figures available for use on her course web pages for students. Well, we certainly should (and our publisher agrees), and would have done this awhile ago if we had thought of it. So, after a few hours of copying and saving with MWSnap, I’ve made an archive of most of the figures in Real-Time Rendering, 3rd edition. It’s a 34 Mb download:

Update: preview and download individual figures on Flickr

This archive should make preparation a lot more pleasant and less time-consuming for instructors, vs. scanning in pages of our book or redrawing figures from scratch. Here’s the top of the README.html file in this archive:

These figures and tables from the book are copyright A.K. Peters Ltd. We have provided these images for use under United States Fair Use doctrine (or similar laws of other countries), e.g., by professors for use in their classes. All figures in the book are not included; only those created by the authors (directly, or by use of free demonstration programs, as listed below) or from public sources (e.g., NASA) are available here. Other images in the book may be reused under Fair Use, but are not part of this collection. It is good practice to acknowledge the sources of any images reused – a link to we suspect would be useful to students, and we have listed relevant primary sources below for citation. If you have questions about reuse, please contact A.K. Peters at [email protected].

I’ve added a link to this archive at the top of our main page. I should also mention that Tomas’ Powerpoint slidesets for a course he taught based on the second edition of our book are still available for download. The slides are a bit dated in spots, but are a good place to start. If you have made a relevant teaching aid available, please do comment and let others know.
