Preface

The 27th International Conference on Computer Graphics and Applications (Pacific Graphics 2019) was held at Korea University, Seoul, Korea, on October 14-17, 2019. Pacific Graphics is a flagship conference of the Asia Graphics Association. Pacific Graphics provides a premium forum for researchers, developers, and practitioners in the Pacific Rim and around the world to present and discuss new problems, solutions, and technologies in computer graphics and related areas. This year Pacific Graphics received 222 submissions, which were reviewed by a Program Committee of 108 international experts and 154 external reviewers. Each submission underwent a rigorous review process. The Program Co-Chairs assigned each paper to a primary reviewer and a secondary reviewer selected from the Program Committee. The primary invited external reviewers so that each paper received at least three reviews. The decision of the first review cycle was made after the authors’ rebuttal and extensive discussions among the reviewers. Each of the accepted full papers underwent a second review cycle to ensure that the necessary revisions indicated in the reviews were carried out. Out of 222 submissions, 74 full papers (acceptance rate: 33.3%) and 9 short papers were selected for oral presentation at the conference. 69 of the full papers are published in the special issue of Computer Graphics Forum and 5 of them will be published in the regular issue of Computer Graphics Forum after major revision. All the accepted full and short papers are published electronically through the EG Digital Library and presented in a two-track format at the conference. The conference program also includes pre- sentations of four recent articles from regular issues of IEEE Transactions on Visualization and Computer Graphics and another four articles from regular issues of Computer Graphics Forum. They are presented together with regular papers. The conference also features three keynote speeches by Markus Gross, Alla Sheffer, and Masahiko Inami. The work-in-progress and poster sessions are an integral part of the conference program, which pro- vides an opportunity for authors to display late-breaking technical achievements that are not yet ready for publication or added on previous publication. While conference attendees receive the abstracts and supplemental material for the work-in-progress and poster program, this material does not appear in any archival libraries since work-in-progress and posters are not formal publications. We wish to thank the members of the international program committee and the external reviewers for doing thorough reviews despite short review and discussion periods. We are also very grateful to Stefanie Behnke for her help with the submission and review management system, Michael Wimmer for providing the paper sorting script, and Hwangpil Park for his help with conference scheduling and administration. Finally, we would like to thank the authors for their support of this venue and congratulate them for the high quality of the papers compiled into the proceedings.

Perception Driven Computational Shape Design

Alla Sheffer

Abstract Humans have developed multiple ways to communicate about both tangible and abstract shape properties. Artists and designers can quickly and effectively convey complex shapes to a broad audience using traditional mediums such as paper, while both experts and the general public can analyze and agree on intangible shape properties such as style or aesthetics. While perception research provides some clues as to the mental processes humans employ when performing these tasks, concrete and quantifiable explanations of these actions are still lacking. Short Biography Alla Sheffer is a professor of Computer Science at the University of British Columbia, where she investigates al- gorithms for shape modeling and analysis in the context of computer graphics applications. She is best known for her research on mesh parameterization, hexahedral meshing, computational garment design, and perception driven shape modeling. Dr. Sheffer is the recipient of the Canadian Human Computer Communications Society Achieve- ment Award’18. Her research has been supported by faculty awards from IBM, Google and Adobe, Discovery, Dis- covery Accelerator and I2I NSERC grants, a Killam research fellowship, and an Audi Production Award. Dr. Sheffer has served as an Associate Editor of all three major computer graphics journals (ACM Transactions on Graphics, IEEE Transactions on Visualization Computer Graphics, and Eurographics Computer Graphics Forum). She served as a program co-chair for Eurographics’18, Symposium on Geometry Processing’06, and Shape Modeling’13. She was a general co-chair for the Pacific Graphics’18 and Geometric Modeling and Processing’19 conferences. Dr. Sheffer had co-authored over 100 peer-reviewed publications, including 42 papers in ACM Transactions on Graph- ics, the topmost competitive CG venue; 22 of these were published in the last five years. She holds six recent patents on methods for sketch analysis and hexahedral mesh generation. Pacific Graphics 2019 Volume 38 (2019), Number 7 C. Theobalt, J. Lee, and G. Wetzstein (Guest Editors)

Virtual Cyborg: Beyond Human Limits

Masahiko Inami

Abstract The social revolutions have accompanied innovation of the view of the body. If we regard the information revolution as establishment of a virtual society against the real society, it is necessary to design a new view of body "JIZAI body (Virtual Cyborg)", which can adapt freely to the change of social structure, and establish a new view of the body. In this talk, we discuss how we understand of basic knowledge about the body editing for construction of JIZAI body (Virtual Cyborg) basedon VR, AR and Robotics. Superhuman Sports: Applying Human Augmentation to Physical Exercise. This talk will also present Superhuman Sports, a form of "Human-Computer Integration” to overcome somatic and spatial limitation of humanity by merging technology with the body. In Japan, official home of the 2020 Olympics and Paralympics , we hope to create a future of sports where everyone, strong or weak, young or old, non-disabled or disabled, can play and enjoy playing without being disadvantaged. Short Biography Masahiko Inami, Ph.D. Professor, Research Center for Advanced Science and Technology, the University of Tokyo Dr. Masahiko Inami took up his current position as professor at the University of Tokyo after working at the Uni- versity of Electro-Communications and Keio University. His interests include “JIZAI body editing technology,” the Augmented Human, and entertainment engineering. He has received several awards, including TIME Magazine’s “Coolest Invention of the Year” award and the Young Scientist Award from the Ministry of Education, Culture, Sports, Science, and Technology (MEXT).
