Courses Scattered Data Interpolation for Computer Graphics Room 314 Presented in English / 영어로 발표 됨 Interpolation is a fundamental topic in computer graphics. While textbooks have generally focused on "regular" interpolation schemes such as B-splines, scattered interpolation approaches also have been a wide variety of applications. These include topics in facial animation, skinning, morphing, rendering, and fluid simulation. This best-practice guide to scattered data interpolation reviews the major algorithms for scattered interpolation, shows how and where they are applied in a variety of published graphics studies, and compares and contrasts them. The algorithms include Shepard interpolation, Wiener interpolation, Laplace and thin-plate interpolation, radial basis functions (RBFs), moving least squares, and kernel regression. The course summarizes stability and computational properties with a focus on real-time applications and provides some theoretical insights to broaden the course's engineering perspective. |

Courses Sorting in Space: Multidimensional, Spatial, and Metric Data Structures for Graphics Applications Room 308A Presented in English / 영어로 발표 됨 Representation of spatial data is an important issue in game programming, computer graphics, visualization, solid modeling, computer vision, and geographic information systems (GIS). Recently, there has been much interest in hierarchical representations such as quadtrees, octrees, and pyramids, based on image hierarchies, as well as methods that use bounding boxes, based on object hierarchies. The key advantage of these representations is that they provide a way to index into space. In fact, they are little more than multidimensional sorts. They are compact and, depending on the nature of the spatial data, they save space and time, and facilitate operations such as search. This course provides a brief overview of hierarchical spatial data structures and related algorithms that make use of them. It describes hierarchical representations of points, lines, collections of small rectangles, regions, surfaces, and volumes. For region data, it points out the dimension-reduction property of the region quadtree and octree, and how to navigate between nodes in the same tree, a main reason for the popularity of these representations in ray-tracing applications. The course also demonstrates how to use these representations for both raster and vector data. In the case of nonregion data, it shows how these data structures can be used to compute nearest objects in an incremental fashion so that the number of objects need not be known in advance. It also reviews a number of different tessellations and shows why hierarchical decomposition into squares instead of triangles or hexagons is preferred. The course concludes with a demonstration of the SAND spatial browser, based on the SAND spatial database system, and presentation of the VASCO JAVA applet. |

Courses "Toy Story 3" Double Feature: Characters and Lighting Room E1-E4 Presented in English, translated simultaneously to Korean / 영어로 발표 됨 (한국어 동시 통역) This course explores rebuilding and relighting the Toy Story characters, their worlds, and their human co- stars, and ensuring that they remained familiar and recognizable to the audiences who saw them 11 years ago in "Toy Story 2". The tools available in computer graphics have significantly improved during the last decade. Technologies such as ambient occlusion, subsurface scattering, efficient Indirect Illumination, and subdivision surfaces either did not exist or were in their infancy when "Toy Story 2" was released in 1999. Audiences have also developed higher expectations for the visuals in contemporary animated films. New and improved technologies add welcome richness and depth, but they must be used carefully, to make sure that familiar characters do not become strangers. For "Toy Story 3", the Pixar team had to rebuild all the models, both characters and sets, yet make them appear exactly the same as their earlier incarnations. As they increased the level of detail and visual richness, they had to maintain a consistent design that would be recognizable from the preceding two films. The course explanations of visual storytelling through lighting, early prototypes of Lotso, and many examples of the team's successes and failures. |

Courses Introduction to Data-Driven Animation: Programming With Motion Capture Room 308A Presented in English / 영어로 발표 됨 Data-driven animation using motion-capture data has become a standard practice in character animation. A number of techniques have been developed to add flexibility on captured human motion data by editing joint trajectories, warping motion paths, blending a family of parameterized motions, splicing motion segments, and adapting motion to new characters and environments. Even with the abundance of motion-capture data and the popularity of data-driven animation techniques, programming with motion capture-data is still not easy. A single clip of motion data encompasses a lot of heterogeneous information including joint angles, the position and orientation of the skeletal root, their temporal trajectories, and a number of coordinate systems. Due to this complexity, even simple operations on motion data, such as linear interpolation, are rarely described as succinct mathematical equations in research papers. This course provides not only a solid mathematical background, but also a practical guide to programming with motion-capture data. It begins with a brief review of affine geometry and coordinate-invariant (conventionally called coordinate-free) geometric programming, which generalizes incrementally to deal with three-dimensional rotations/orientations, the poses of an articulated figure, and full-body motion data. Then it identifies a collection of coordinate-invariant operations on full-body motion data and their object-oriented implementation. Finally, it explains the practical use of this programming framework in a variety of contexts ranging from data-driven manipulation and interpolation to state-of-the-art biped locomotion control. |

Courses Cross-Cultural User-Interface Design Room 308A Presented in English / 영어로 발표 됨 User interfaces for desktop, web, mobile, and vehicle applications reach across culturally diverse user communities, sometimes within a single country or language group, and certainly throughout the world. If user interfaces are to be usable, useful, and appealing to such a wide range of audiences, user-interface and user-experience developers must account for cultural preferences in globalizing and localizing products and services. In this tutorial, attendees learn about culture models, culture characteristics, and practical principles and techniques of design and analysis that are immediately useful in both current and next-generation products and services. As the course concludes, attendees have an opportunity to put their new understanding into practice through a series of pen-and-paper exercises. |

Courses Introduction to Computer Graphics Room 314 Presented in English, translated simultaneously to Korean / 영어로 발표 됨 (한국어 동시 통역) A SIGGRAPH conference is an exciting event, but it is often an intimidating experience for first-time attendees. There are so many new terms, new ideas, and new product concepts to try to understand. It is like standing in a room with 100 doors and having no idea which door to open because you have no idea what the label on each door actually means. This leaves new attendees baffled and frustrated about how to spend their time. This course is designed to ease newcomers into the SIGGRAPH Asia conference experience by presenting the fundamental concepts and vocabulary at a level that can be readily understood. Far from being made up of dry facts, this course will also portray the fun and excitement that led most of us here in the first place. Attendees in the course will become well-prepared to understand, appreciate, enjoy, network, and learn from the rest of the SIGGRAPH Asia experience. This is a half-day Beginning course. This course will be given lecture-style. There will be PowerPoint slides and live demos showing the use of computer graphics in applications These will be used to illustrate fundamental concepts (e.g., here is an image with and without perspective) and to illustrate those concepts in applications (e.g., here is the use of perspective in a visualization application and why you have to be careful when using it). The source code for the graphics program demos will be included on the conference DVD so that attendees can use them in their own applications and classes as well. Because this is the first time that SIGGRAPH is being held in Korea, an introductory course taught by experienced practioners will be an important aspect of the conference. |

Courses Efficient Substitutes for Subdivision Surfaces in Feature-Quality Games Room E5 Presented in English / 영어로 발표 됨 As real-time graphics aspires to movie-quality rendering, higher-order, smooth-surface representations take center stage. Catmull-Clark subdivision surfaces are the dominant higher-order surface type used in feature films, as they can model surfaces of arbitrary topological type and provide a compact representation for smooth surfaces that facilitate modeling and animation. But their use has been hindered in real-time applications because the exact evaluation of such surfaces on modern GPUs is neither memory nor performance efficient. The advent of DirectX 11, recent theoretical results in efficient substitutes for subdivision surfaces, and recent hardware advances offer the possibility to see real-time cinematic rendering in the near future. This course covers the hardware tessellation part of the SIGGRAPH 2009 Course Efficient Substitutes for Subdivision Surfaces with the emphasis on character tessellation in movie-quality games. It adds additional material based on recent research findings and practical optimizations. The goal of this course is to familiarize attendees with the practical aspects of introducing substitutes in subdivision surfaces to increase efficiency in real-time applications. The course begins by highlighting the properties that make SubD modeling attractive and introduces some recent techniques to capture these properties by alternative surface representations with a smaller foot-print. It lists and compares the new surface representations and focuses on their implementation on current and next-generation GPUs, then addresses crucial practical issues, such as watertight evaluation, creases and corners, view-dependent displacement occlusion mapping, and LOD computation. Finally and most importantly, it explains how these advanced techniques have been adopted into their gaming pipelines. |

Courses Procedural Shading in RenderMan Room E6 Presented in English, translated simultaneously to Korean / 영어로 발표 됨 (한국어 동시 통역) Proceduralism is a powerful concept in computer graphics. It facilitates scenes of enormous scale, exquisite varieties of detail, and impressive efficiency. However, artists who are fluent in procedural techniques are still rare, and many studios miss out on the possibilities that this exciting field offers. This course explores how to create procedural shaders without programming, using Pixar's industry standard renderer, RenderMan, and its Autodesk Maya-based front-end, RenderMan Studio. The second section is a live demonstration of how to create a procedural animated shader for an orange that ages over time, from unripe to fresh to old and dusty. The demo begins with a sphere in Maya, then shows how to create all the detail using a shading network in RenderMan Studio. No textures are used. The look is created entirely with noise, splines, displacement, and more! Finally, the course presents examples of how the techniques used in shading the orange apply in industry and beyond. |

Courses Introduction to OpenCL by Example Room 308B/C Presented in English / 영어로 발표 됨 The rapidly changing capabilities of modern graphics processing units (GPUs) require that developers understand how to combine parallel-programming techniques with the traditional interactive rendering pipeline exposed by OpenGL and Direct3D. This course demonstrates how to combine traditional rendering APIs with advanced parallel computation using OpenCL (Open Computing Language), a cross-platform API for programming parallel systems such as GPUs. The course presenters are experts on general-purpose GPU computation and advanced rendering from academia and industry, and have presented papers and tutorials on the topic at SIGGRAPH, Graphics Hardware, Supercomputing, and elsewhere. The first section reviews the basics of the OpenCL API, including a "Hello World" application written in OpenCL. Attendees with laptops will be able to try the examples on their own during the course. The second section covers more advanced cases, including how to write applications that interact with standard graphics APIs. The final section includes performance-optimization "tips and tricks" for writing OpenCL applications. |

Featured Speakers Design for Speed Auditorium Presented in English, translated simultaneously to Korean / 영어로 발표 됨 (한국어 동시 통역) Inside the studios of one of the world's most technologically advanced automotive and racing companies, a lump of clay, an organic expression of a next-generation car, sits near a supercomputer that visualizes the car in a virtual environment that is almost impossible to distinguish from real life. The studio walls are covered with images and examples of natural objects and technological tours de force; animals, jet fighters, exotic new materials, and even the world’s fastest sailfish splashed in chrome with McLaren’s rocket red accents. The studio's designers are constantly debating and exploring new technologies, new materials, and new concepts. Technology has changed the way designers work. Traditional design phases, from hand-drawn sketches to clay modeling, are now realized through digital tablets and digital three-dimensional modeling. Designers must combine the best traditional and new approaches to define the optimal balance between digital and analog solutions. Automobiles have always been a reflection of technology draped in art, and "super cars" are the ultimate expression of automotive art and technology. Designers who create the next generation of super cars must have the right tools to articulate their vision. At the same time, they must always ask: What’s next? With its roots in Formula One racing, the design studio at McLaren is where "what’s next" is already here. In his featured speech, McLaren Design Director Frank Stephenson explains how his world-class design team looks beyond what's next to challenge the future. |

Exhibitor Tech Talks Real-Time Shading in Wave3D Exhibitor Tech Talk Stage Presented in Korean / 한국어로 발표 됨 Shading indicates a shadow effect on the target that will be rendered for normal CG. Real-time rendering has a different meaning. Response is very important in real-time rendering. It processes commands through hardware to calculate GPU graphics. In the "shader module", a programmable module processes the vertex and the pixel, and the CPU becomes less flexible and provides less time for calculation. Solving these problems requires an algorithm that focuses on visual effects rather than accuracy in a standardized data structure. |
