Game Technology and Beyond: Destination Vancouver

2011 is an exciting year for game developers at SIGGRAPH, with a record amount of game development content throughout various conference programs, including Courses, Talks, Papers, SIGGRAPH Dailies, and Real-Time Live!


Advances in Real-Time Rendering in Games Parts I and II
Natalya Tatarchuk, Bungie, Inc.; John White, Electronic Arts Black Box; Colin Barré-Brisebois, Electronic Arts Montréal; Dimitar Lazarov, Treyarch; Vassily Fillipov, Sony Santa Monica; Hugh Malan, CCP Games; Christopher Hall, Avalanche Software; Robert Hall, Avalanche Software; David Edwards, Avalanche Software; Eric Penner, Electronic Arts Vancouver

Part I links the game development community and state-of-the-art 3D graphics research, encouraging cross-pollination for future games and other interactive applications. The focus of Part II, the next installment in the now-established series of SIGGRAPH courses on real-time rendering, is on bridging the game-development community and state-of-the-art 3D graphics research to encourage cross-pollination of knowledge for future games and other interactive applications.

Filtering Approaches for Real-Time Anti-Aliasing
Instructors: Jorge Jimenez and Diego Gutierrez, Universidad de Zaragoza; Jason Yang, Advanced Micro Devices, Inc.; Alexander Reshetov, Intel Labs; Pete Demoreuille, Double Fine Productions, Inc.; Tobias Berghoff and Cedric Perthuis, Sony Computer Entertainment; Henry Yu, Kalloc Studios; Morgan McGuire, NVIDIA Corporation and Williams College; Timothy Lottes, NVIDIA Corporation; Hugh Malan, CCP hf.; Emil Persson, Avalanche Studios; Dmitry Andreev, Lucas Arts; Tiago Sousa, Crytek

For more than a decade, supersample anti-aliasing (SSAA) and multisample anti-aliasing (MSAA) have been the gold-standard anti-aliasing solutions in games. However, these techniques are not well suited for deferred shading or fixed environments like the current generation of consoles. In recent years, industry and academia have been exploring alternative approaches, where anti-aliasing is performed as a post-processing step. The original, CPU-based morphological anti-aliasing (MLAA) method gave birth to an explosion of real-time anti-aliasing techniques that rival MSAA. Most of these techniques share concepts and ideas, so the main goal of this course is to establish a conceptual link between them, identifying novelties and differences.

This year, SIGGRAPH 2011 has an unprecedented number of Talks with game industry speakers at the conference.

Deferred Shading Technique Using Frostbite in Battlefield 3 and Need for Speed: The Run
Alex Ferrier, Electronic Arts; Christina Coffin, DICE (Electronic Arts)
A technical and production-oriented talk describing the tile-based lighting architecture and deferred rendering optimizations developed to achieve a visual target with hundreds of real-time lights per scene for Battlefield 3 and Need for Speed The Run at 30 frames per second on PlayStation3 and Xbox 360.

Occlusion Culling in Alan Wake
Ari Silvennoinen and Teppo Soininen, Umbra Software Ltd; Markus Mäki and Olli Tervo, Remedy Entertainment, Ltd.
This talk discusses implementation of the occlusion culling system used in Alan Wake and presents details on how the system efficiently supports shadow-caster culling for dynamic light sources in large environments.

Other game development Talks at SIGGRAPH 2011 include:

  • Spherical Skinning With Dual Quaternions and QTangents
  • Rendering the Interactive Dynamic Natural World of the Game: From Dust
  • Animation Workflow in Killzone 3: A Fast Facial Retargeting System for Game Characters
  • Increasing Scene Complexity: Distributed Vectorized View Culling
  • Practical Occlusion Culling in Killzone 3
  • High-Quality Previewing of Shading and Lighting for Killzone 3
  • Modular Rigging in Battlefield 3
  • Fluid Dynamics and Lighting Implementation in PixelJunk Shooter 2
  • Making Faces: Eve Online's New Portrait Rendering
  • Runtime Implementation of Modular Radiance Transfer
  • Motorstorm Apocalypse: Creating Urban Off Road Racing

Real-Time Live!

Real-Time Live! is the premiere showcase for the latest trends and techniques for pushing the boundaries of interactive visuals. As part of the Computer Animation Festival, an international jury selected submissions from several areas, including games, animation, performance, and visualization.

Paul Amer, Microsoft Games Studios
Kinectimals enables players to reach beyond the fourth wall and interact with a virtual pet using the Kinect sensor technology. Kinectimals showcases Frontier's Cobra engine and their latest-generation animation system.

A Look Under the Hood of Need for Speed: Hot Pursuit
Henry LaBounta, Electronic Arts; Alex Fry, Criterion Games - Electronic Arts
Need for Speed: Hot Pursuit used image-based lighting for the forward-rendered cars to help them look integrated with the deferred-rendered environment, which dynamically changes with a full-day cycle of light and weather. A custom anti-aliased line-rendering technique greatly improved the aliasing artifacts that are common to deferred rendering.

Samaritan Real-Time Demo

Paul Oliver, Chris Perna, Jordan Walker, Michael Clausen, Zak Belica, Gavin Moran, Jay Hosfelt, Epic Games Inc.
Samaritan is a real-time demonstration of the latest Unreal Engine 3 technology that shows off DirectX 11 support and DirectX features such as tessellation and displacement mapping, geometry shaders, multi-sampled textures and Shader Model 5.


Game Papers
Game Papers explore key issues in video games, inform and substantively advance our current state of knowledge and understanding, and foster new areas for investigation that will drive the next generation of design and player experience. The following sessions include multiple Game Papers.


Technical Papers

Depixelizing Pixel Art
Johannes Kopf, Microsoft Research Redmond; Dani Lischinski, The Hebrew University
A novel algorithm for extracting a resolution-independent vector representation from small pixel art images, which enables magnifying the results by an arbitrary amount without image degradation. Pixel-scale features are resolved and converted into regions with smoothly varying shading that are crisply separated by piecewise-smooth contour curves.
