Preface

The 23rd Pacific Conference on Computer Graphics and Applications (Pacific Graphics 2015) was held inBeijing, China, on October 7-9, 2015. As a highly successful conference series, Pacific Graphics providesa premium forum for researchers, developers, practitioners in the Pacific Rim and around the world topresent and discuss new problems, solutions, and technologies in computer graphics and related areas.

There were 157 papers submitted, which were reviewed by a program committee of 115 internationalexperts, as well as 179 external reviewers. Of these submissions, 33 papers were selected for full oralpresentation at the conference, as well as for inclusion in this issue of Computer Graphics Forum. Eachpaper was reviewed by at least 4 reviewers from the program committee and the external experts. Eachof the accepted papers underwent a second review cycle to ensure that the necessary revisions indicatedin the reviews were carried out.

In addition to the paper presentation, the conference also featured three invited talks by Peter Wonka,Nobuyuki Umetani, and Kun Zhou. There was also a short paper session, where 14 short papers werepresented. The short papers are published electronically through the EG Digital Library.

The topics of the papers in this volume are diverse, including geometric modeling, rendering, animation,simulation, images/videos, and visualization. Some of the papers were submitted with supplementarymaterials that EUROGRAPHICS members can access through the EG website.

We would like to thank the authors and participants at the conference, the program committee members,and the external reviewers, all of whom made their best effort to ensure the high quality of the PacificGraphics 2015 technical program. We also wish to thank Tsinghua-Tencent Internet Innovation Technol-ogy Joint Laboratory for their financial support. Finally, we would like to thank Stefanie Behnke, whoseadministrative and technical help was invaluable.

Computational Design of Urban Layouts

Peter WonkaProfessor of Computer Science at King Abdullah University of Science andTechnology (KAUST) and Arizona State University

AbstractA fundamental challenge in computational design is to compute layouts by arranging a set of shapes.In this talk I will present recent urban modeling projects with applications in computer graphics, urbanplanning, and architecture. The talk will look at different scales of urban modeling (streets, floorplans,parcels). A common challenge in all these modeling problems are functional and aesthetic constraints thatshould be respected. The talk also highlights interesting links to geometry processing problems, such asfield design and quad meshing.



Invited Talk

Simulation-guided Interactive Exploration of Functional Design

Nobuyuki UmetaniResearch Scientist at Autodesk Research

AbstractPhysical simulation allows validation of geometric designs without tedious physical prototyping. How-ever, since geometric modeling and physical simulation are typically separated, simulations are mainlyused for rejecting bad design, and not for assisting creative exploration towards better designs. In thistalk, I introduce several interactive approaches to integrate physical simulation into geometric model-ing to actively support creative design process. Importance of interactivity in the design system will bediscussed in various practical contexts including structurally robust design, musical instrument design,garment design, and aerodynamics design.

Digital Avatars for All: Interactive Face and Hairs

Kun ZhouCheung Kong Professor and Director of the State Key Lab ofCAD&CG at Zhejiang University

AbstractAlthough realistic face/hair modeling and animation technologies have been widely employed in com-puter generated movies, it remains challenging to deploy them in consumer-level applications such ascomputer games, social networks and other interactive applications. The main difficulties come from therequirement of special equipment, sensitivity to daily environments, laborious manual work and highcomputational costs. In this talk, I will introduce our recent work on realistic face/hair modeling andanimation, targeting at interactive applications and ordinary users. In particular, I will describe fully au-tomatic approaches to real-time facial tracking and animation with a single web camera, methods formodeling hairs from images, and real-time algorithms for realistic hair simulation.
