Fu Courses Principles of Animation Physics Room 502AB Details
Principles of Animation Physics
An understanding of physics is essential for creating believable animated motion. Many basic concepts in animation (such as follow-through, drag, and weight shift) are clearer when considered in the context of basic mechanics.
This course was developed with support from the National Science Foundation by Alejandro Garcia, who was on leave at the Department of Artistic Development at DreamWorks Animation SKG, where he presented over 30 classes and special lectures on physics as it applies to animation. The course covers essential topics from physical mechanics to basic bio-mechanics that apply specifically to character animation.

Fu Courses State-of-the-Art Stereoscopic Visual Effects: Stereoscopy and Conversion are “More than Meets the Eye” South Hall K Details
State-of-the-Art Stereoscopic Visual Effects: Stereoscopy and Conversion are “More than Meets the Eye”
A recent surge in production of 2D-to-3D converted films has established this technique as a permanent part of the stereoscopic entertainment industry. Proper conversion is not a simplistic post-production process. It requires exceptionally complex and nuanced stereoscopic visual effects that, if improperly applied, can result in poor quality films and physical pain on the part of the audience.
This course presents case studies from Digital Domain's recent stereoscopic conversions (for example, "Transformers 3") that demonstrate how to convert high-quality stereoscopic content through both traditional and hybrid stereoscopic workflows. It also explains in detail how proper conversion is mathematically identical to geometry generated from stereoscopic capture, shows how to articulate and identify poor quality conversion, reviews when it is appropriate to convert materials, and provides tips on how to shoot specifically for 2D-to-3D conversion.

Fu Panels Virtual Production Branches Out Room 502AB Details
Virtual Production Branches Out
Virtual production is changing how directors, actors, and stories interact. The ability to capture the subtleties of actors’ performance digitally and move digital-environment data among pre-production, production, and post is opening up new worlds, new kinds of characters, and new ways of telling stories.
After gaining wide public visibility on "Avatar", virtual production is sweeping through the feature film world – and beyond. Because blending live and CGI elements is not only possible, but now practical, virtual production has been embraced to improve the standard of previsualization, to augment motion capture in games creation to enhance overall quality, and to enable film directors to see more of what their world will look like while they’re in production. In short, virtual production has branched out.
A panel of leading virtual-production practitioners discusses and debates:
• Advances and considerations in motion capture
• Relative benefits of separate vs. in-scene facial capture
• SimulCam – its evolution and where it is heading
• The client/filmmaker experience

Fu Courses Practical Physically-Based Shading in Film and Game Production Room 515AB Details
Practical Physically Based Shading in Film and Game Production
Physically based shading is increasingly important in both film and game production. By adhering to physically based, energy-conserving shading models, one can easily create high-quality, realistic materials that maintain that quality under a variety of lighting environments. Traditional “ad-hoc” models require extensive tweaking to achieve the same result, so it is no surprise that physically based models have increased in popularity in film and game production, particularly because they are often no more difficult to implement or evaluate.
This course was last presented at SIGGRAPH 2010. With extensive updates, the SIGGRAPH 2012 course presents two years of advances in physically based shading. It includes new research in the area and more production examples from film and game. The course begins with a brief introduction to the physics and mathematics of shading before instructors share examples of how physically based shading models are being used in production. Real-world examples are a particular focus of this year’s course, which is designed to give attendees a practical grounding in the subject.

Fu Courses FEM Simulation of 3D Deformable Solids: A Practitioner's Guide to Theory, Discretization, and Model Reduction Room 408B Details
FEM Simulation of 3D Deformable Solids: A Practitioner's Guide to Theory, Discretization, and Model Reduction
A practical guide to finite-element-method (FEM) simulation of 3D deformable solids reviews essential offline FEM simulation techniques: complex nonlinear materials, invertible treatment of elasticity, and model-reduction techniques for real-time simulation.
Simulations of deformable solids are important in many applications in computer graphics, including film special effects, computer games, and virtual surgery. FEM has become a popular method in many applications. Both offline simulation and real-time techniques have matured in computer graphics literature.
This course is designed for attendees familiar with numerical simulation in computer graphics who would like to obtain a cohesive picture of the various FEM simulation methods available, their strengths and weaknesses, and their applicability in various simulation scenarios. The course is also a practical implementation guide for the visual-effects developer, offering a very lean yet adequate synopsis of the underlying mathematical theory. The first section introduces FEM deformable-object simulation and its fundamental concepts, such as deformation gradient, strain, stress, and elastic energy, discusses corotational FEM models, isotropic hyperelasticity, and numerical methods such as conjugate gradients and multigrid. The second section presents the state of the art in model reduction techniques for real-time FEM solid simulation. Topics include linear modal analysis, modal warping, subspace simulation, domain decomposition, and which techniques are suitable for which application.
