The Metaverse and Digital Realities Transcript Introduction Plenary
[Scientific Innovation Series 9] The Metaverse and Digital Realities Transcript Date: 08/27/2021 (Released) Editors: Ji Soo KIM, Jooseop LEE, Youwon PARK Introduction Yongtaek HONG: Welcome to the Chey Institute’s Scientific Innovation Series. Today, in the 9th iteration of the series, we focus on the Metaverse and Digital Realities. I am Yongtaek Hong, a Professor of Electrical and Computer Engineering at Seoul National University. I am particularly excited to moderate today’s webinar with the leading experts and scholars on the metaverse, a buzzword that has especially gained momentum during the online-everything shift of the pandemic. Today, we have Dr. Michael Kass and Dr. Douglas Lanman joining us from the United States. And we have Professor Byoungho Lee and Professor Woontack Woo joining us from Korea. Now, I will introduce you to our opening Plenary Speaker. Dr. Michael Kass is a senior distinguished engineer at NVIDIA and the overall software architect of NVIDIA Omniverse, NVIDIA’s platform and pipeline for collaborative 3D content creation based on USD. He is also the recipient of distinguished awards, including the 2005 Scientific and Technical Academy Award and the 2009 SIGGRAPH Computer Graphics Achievement Award. Plenary Session Michael KASS: So, my name is Michael Kass. I'm a distinguished engineer from NVIDIA. And today we'll be talking about NVIDIA's view of the metaverse and how we need an open metaverse. And we believe that the core of that metaverse should be USD, Pixar's Universal Theme Description. Now, I don't think I have to really do much to introduce the metaverse to this group, but the original name goes back to Neal Stephenson's novel Snow Crash in 1992, and the original idea probably goes back further.

An Introduction to Physically Based Modeling: an Introduction to Continuum Dynamics for Computer Graphics
An Introduction to Physically Based Modeling: An Introduction to Continuum Dynamics for Computer Graphics Michael Kass Pixar Please note: This document is 1997 by Michael Kass. This chapter may be freely duplicated and distributed so long as no consideration is received in return, and this copyright notice remains intact. An Introduction to Continuum Dynamics for Computer Graphics Michael Kass Pixar 1 Introduction Mass-spring systems have been widely used in computer graphics because they provide a simple means of generating physically realistic motion for a wide range of situations of interest. Even though the actual mass of a real physical body is distributed through a volume, it is often possible to simu- late the motion of the body by lumping the mass into a collection of points. While the exact coupling between the motion of different points on a body may be extremely complex, it can frequently be ap- proximated by a set of springs. As a result, mass-spring systems provide a very versatile simulation technique. In many cases, however, there are much better simulation techniques than directly approximating a physical system with a set of mass points and springs. The motion of rigid bodies, for example, can be approximated by a small set of masses connected by very stiff springs. Unfortunately, the very stiff springs wreak havoc on the numerical solution methods, so it is much better to use a technique based on the rigid-body equations of motion. Another important special case arises with our subject here: elastic bodies and ¯uids. In many cases, they can be approximated by regular lattices of mass points and springs.

A System for Efficient 3D Printed Stop-Motion Face Animation
A system for efficient 3D printed stop-motion face animation RINAT ABDRASHITOV, ALEC JACOBSON, KARAN SINGH, University of Toronto Fig. 1. Given an input mesh-animation sequence (a), our system segments and deforms the 3D mesh into parts that can be seamlessly joined (b). Each part is independently used to compute a replacement library, representative of the deforming part in the input (c). StopShop iteratively optimizes the library and a mapping from each frame of the input animation to the pieces in the library. Libraries are 3D printed and each frame is assembled according to the optimized mapping (d). Filmed in sequence, the animation is realized as a stop motion film (e). Computer animation in conjunction with 3D printing has the potential to used as the preferred technique for producing high-quality facial positively impact traditional stop-motion animation. As 3D printing every animation in stop motion film [Priebe 2011]. frame of a computer animation is prohibitively slow and expensive, 3D Faces and 3D models in general are created digitally (or physi- printed stop-motion can only be viable if animations can be faithfully re- cally sculpted and scanned) to produce a replacement library that produced using a compact library of 3D printed and efficiently assemblable covers the expressive range of the 3D model.

Meet Geri: the New Face of Animation
SAVE THIS | EMAIL THIS | Close Meet Geri: The New Face of Animation Meet Geri: The New Face of Animation Pixar`s new short film advances the art and science of character animation Barbara Robertson The marriage of technology and art is not always an easy alliance. Taken to its extreme, the partnership pits left brain versus right brain, logic versus feeling, cold versus warm. Yet out of this conflict, a kind of creativity can emerge that neither side could produce alone. In the history of computer graphics, there are numerous beautiful examples of this creativity--and some of the most brilliant have been produced at Pixar Animation Studios. The most recent blending of Pixar`s state-of-the-art graphics technology with story-telling and animation, is Geri`s Game, a 4-1/2-minute animated short film that premiered in Los Angeles last November, in the nick of time for Academy Award Nominations. Academy Award honors are not new at Pixar: John Lasseter received a nomination in 1986 for Luxo, Jr. and an Oscar in 1988 for Tin Toy. What`s new is that this film marks the debut of a new director at Pixar, Jan Pinkava, and that Pinkava`s film is the first short animation to be produced by Pixar in eight years. Whether or not Geri`s Game joins its predecessors at Pixar by receiving an Oscar nomination this year, the film is likely to have as much impact on computer graphics animation as Pixar`s earlier shorts did--in terms of both art and technology.

Throughout my time at UC Davis, I have had the great fortune to work with an outstand- ing collection of colleagues at UC Davis, Pixar, the University of Utah, Stanford, NVIDIA, the University of North Carolina, the University of Virginia and elsewhere. I begin by thanking my advisor, John Owens. I consider the most important traits in a graduate advisor to be trust and a passionate interest in my work. John has provided everything I needed to succeed and repeatedly put my best interests before his own. His passion for and interest in my work propelled me through the inevitable low points of research and encouraged me to take the risks required for true innovation. I cannot thank John enough for promoting my work and giving me the freedom to explore, even when it meant that I published four papers that are not part of this thesis. I also want to thank my committee members, Ken Joy, Bernd Hamann, Oliver Staadt, and Nina Amenta, for their feedback and comments.
