Beyond the content directly related to game development, film production topics are also often relevant to game developers. One example is the use of spherical harmonics and precomputed occlusion in “Avatar”, as discussed in two Talks and one Technical Paper . Other examples can be found among the many film production presentations by the makers of films such as “2012”, “Alice in Wonderland” , “Avatar”, “How to Train Your Dragon”, “Iron Man 2”, “Shrek Forever After”, “Tangled”, “The Last Airbender”, “Toy Story 3”, and “TRON: LEGACY”.
In addition to practical production techniques of short-term interest, SIGGRAPH 2010 also presents forward-looking research that is likely to guide future developments. The Technical Papers program presents advanced graphics research, Panels speculate on future research directions, and Emerging Technologies features hands-on demonstrations of novel interaction methods and devices.
And opportunities for informal collaboration and exchange are everywhere. Throughout the week, SIGGRAPH 2010 attendees meet, network, and talk shop with the world’s top computer graphics talents.
See you in LA!

Gazing at Games: Using Eye Tracking to Control Virtual Characters
Wednesday, 28 July | 3:45 PM
This introduction to attention, eye movements, and eye-tracking technologies summarizes previous work in the field of gaze in gaming and presents two case studies in which gaze and voice were combined to control virtual characters and their behavior. The first case study, The Revenge of the Killer Penguins, is a third-person adventure-puzzle game that combines non-intrusive eye-tracking technology and voice recognition to create novel game features. The second case study, Rabbit Run, is a first-person maze game created to compare gaze and voice input with traditional techniques, such as mouse and keyboard controls. The course reviews the lessons learned in these case studies and issues relating to incorporating eye tracking in games. It also proposes ideas for how this field can be developed further to create richer interaction for characters and crowds in virtual environments.

The Making of God of War III
Thursday, 29 July | 9:00 AM
The makers of God of War III detail the creative process behind the game's ground-breaking visuals. The first part of the session follows the lead character, Kratos, from initial concept art through modeling to animation, with particular emphasis on issues specific to game animation, such as integration with player control and combat systems. The second part focuses on the game's environments and explores various approaches used to create game levels from initial concept art.
Beyond Programmable Shading I
Thursday, 29 July | 9:00 AM
There are strong indications that the future of interactive graphics programming is a more flexible model than today’s OpenGL and Direct3D pipelines. So graphics developers need to have a basic understanding of how to combine emerging parallel programming techniques and more flexible graphics processors with the traditional interactive rendering pipeline. As the first in a series, this course introduces the trends and directions of this emerging field, parallel graphics architectures, parallel programming models for graphics, and researchers
who are investigating the use of these new capabilities in future rendering engines.

Advanced Techniques in Real-Time Hair Rendering and Simulation
Thursday, 29 July | 9:00 AM
Hair rendering and simulation have always been challenging, especially in real time. Due to their high computational demands, they have been largely omitted in real-time applications and studied by only a small group of graphics researchers and programmers. Recent advancements in graphics hardware and software have made real-time hair rendering and simulation possible, but achieving acceptable levels of performance and quality requires specific expertise and experience.
This course reviews accumulated knowledge in real-time hair rendering and simulation, and shows how it can be applied in video games and other real-time applications. It begins with the fundamental techniques for real-time hair rendering and then presents alternative approaches, tips and tricks to achieve better performance and/or quality, an overview of various hair-simulation techniques, and implementation details of the most efficient techniques for real-time applications. The Course Notes include example source code.

User-Generated Terrain in ModNation Racers
This talk discusses implementation of the terrain system in the PlayStation 3 title ModNation Racers and presents details on how the system's map and brush modules work together to efficiently support user editing of all terrain parameters.
Irradiance Rigs
Popular character-lighting techniques in games suffer from inaccuracies with large objects or near-field lighting. This talk present an error-driven approach for dynamic transition between near- and far-field lighting. It also includes a more accurate model for sampling near-field lighting from disks and a flexible reflectance model.
Practical Morphological Anti-Aliasing on the GPU
This real-time method of morphological anti-aliasing on the GPU allows the use of anti-aliasing as a post process, based on a new line-length computation.
Curvature-Dependent Reflectance Function for Rendering Translucent Materials
A method for approximating the effects of subsurface scattering using a curvature-dependent reflectance function. Since the function is a local illumination model, the method synthesizes realistic translucent materials in real time. It can be easily used to stylize subsurface scattering effects.

Beyond Programmable Shading II
Thursday, 29 July | 2:00 PM
There are strong indications that the future of interactive graphics programming is a more flexible model than today’s OpenGL and Direct3D pipelines. So graphics developers need to have a basic understanding of how to combine emerging parallel programming techniques and more flexible graphics processors with the traditional interactive rendering pipeline. This course presents the state of the art in combining traditional rendering API usage with advanced task- and data-parallel computation to increase the image quality of interactive graphics.
Leaders from graphics hardware vendors, game development, and academic research present case studies that show how general parallel computation is being combined with the traditional graphics pipeline to boost image quality and spur new graphics algorithm innovation. Each case study discusses the mix of parallel programming constructs used, details of the graphics algorithm, and how the rendering pipeline and computation interact to achieve the technical goals. The focus is on demonstrating what can currently be done, showing how it is done, and pointing out near-future trends. Topics include volumetric and hair lighting, alternative rendering pipelines including ray tracing and micropolygon rendering, in-frame data structure construction, complex image processing, and the future of graphics programming models.
