I. INTRODUCTION
The 24th Computer Graphics International, or shortly CGI 2006,
was successfully held in Zhejiang University, Hangzhou, China,
June 26-28, 2006. The international conference is supported by
National Natural Science Foundation of China and K. C. Wong
Education Foundation.
The Computer Graphics International is a serial
annually-held conference founded by the Computer Graphics
Society since 1983. These years, this conference has been held
around the world, including New York, U.S. (2005), Crete,
Greece (2004), Tokyo, Japan(2003), Bladderwort U.K. (2002),
Hong Kong, China (2001), Geneva, Swiss (2000). And this
year, it is the first time that the conference is held in the
mainland part of China. The conference was jointly hosted by
State Key Laboratory of CAD&CG and Microsoft Research
Asia, and was greatly supported by China Computer Federation,
Chinese Association of Automation and China Society of
Image and Graphics.
There were more than 120 attendees in this conference from
all over the world, including China, U.S., Germany, Swiss,
France, U.K., Korea, Japan, Belgium, Brazil, Singapore, India
and so on. The conference also attracted a lot of Chinese
dominant researchers and students from more than 20 research
units, such as, Chinese Academic association, Beijing
University, Tsinghua University, Shanghai Jiaotong University,
Fudan University, Huazhong University of Science and
Technology, and Zhejiang University and so on. Graphics
industry, for instance, nVidia, Microsoft and Huawei Inc, also
sent representatives and investigators to attend the conference.
CGI 2006 received over 380 submissions from 22 different
countries. It was a new record in the history of this serial
international graphics conference. According to the restrict
review reports from international reviewers, 37 regular papers
and 38 short papers were finally accepted to be presented in the
conference. The proceedings would be published as Lecture
Notes in Computer Science Volume 4035 by the Springer
Express, which is one of the top publishers of the world. To
encourage researchers taking part in this conference, the
conference also selected 20 conference papers to be published
in the Journal of Zhejiang University, Serial A.
Due to the blooming of information and telecommunication
industry during last decade, computer graphics has been made
more and more close connections to the new technologies, e.g.,
the digital image, video processing, virtual reality, human
interaction and etc. And now computer graphics becomes a
multiple-crossed research field. Compared with computer
graphics researches in the early days, modern computer
graphics have following trends: (1) real-time rendering via
graphics hardware acceleration; (2) data driven realistic
modeling; (3) the merging of rendering and modeling. The fast
technology development of multi-media, virtual reality,
simulation and network stimulate highly the digital
entertainment, in terms of software R&D, hardware
manufacturing, product selling and services in the business of
electronic game, education entertainment, and digital
video/audio. Therefore, one of the central topics of the
conference is the merging of digital entertainment and
computer graphics.
Computer Graphics International is a top level academic
conference started up by the Computer Graphics Society. CGI
2006 provided a good chance to strengthen the research
relationship among Chinese researchers and international
computer graphics specialists.
II. OVERVIEW OF CGI 2006
The theme of CGI 2006 is “digital entertainment and
computer graphics”, which dedicated to discuss how to evolve
the requirements of digital entertainment into the compute
graphics research. Hence the organization committee invited
several well-known specialists in this area to introduce
successful experiences on international movie industry,
computer animation and electronic games, and aimed at
encouraging technology communication and stimulating
application developments. Prof. Dr. Hans-Peter Seidel is one of
the invited speakers; he is the scientific director and chair of the
computer graphics group at the Max-Planck-Institute
Informatik and a professor of computer science at the
University of Saarbrücken, Germany. In 2002 he was awarded
the ‘Leibniz Preis’, the most prestigious research award from
the German Research Foundation. And he is on the editorial
board of IEEE Transactions on Visualization and Computer
Graphics (TVCG), International Journal of Shape Modeling

CGI 2006 also invited Prof. Paul Debevec, who is a senior
researcher being known as a frontier on image based modeling
and rendering. Moreover, he was awarded the Significant New
Researcher Award. Two other invited speakers are Dr. Michael
Kass from Pixar Inc. and Prof. Daniel Thalmann from EFPL.
Both of them are famous computer graphics specialists.
CGI 2006 forked 3 threads and made 22 sessions for
participants to discuss academic papers. The discussion
contents covered realistic rendering, geometry computing, new
graphics techniques, visualization, image and video processing,
texture syntheses, image based rendering, image retrieval,
virtual reality, graphics hardware etc. The conference also
arranged a posting area for authors to present their novel
research results in billboard form.
III. NEWEST RESEARCH RESULTS AND TREND PUBLISHED IN CGI 2006
In the area of computer graphics rendering and animation,
researchers unveiled several new progresses by combing
newest GPU techniques. Prof. Yoshinori Dobashi from Tokyo
University, Japan introduced one of their resent works on
real-time water rendering, Dr. Byung-Seok Roh reported an
interesting technique on cotrolable smoke animaiton, and Prof
Enhua Wu from University of Macau presented how to
generate water caustic effects. Facing the chanllenges in the
area of non-photo-releastic rendering and carton style
rendering, Korean researcher Jin Wan Park reported a novel
method on generating multi-layer mosaic texture using
rotatable objects; Prof. Fabian Di Fiore from Belgium
presented a set of techniques on high stylized sketch-based
animation; and Prof. Oliver Deussen from Germany proposed
applying modified wang-tile techqniue on simulating and
visulizing plant competition. CGI 2006 also made a special
topic on discussing 3-dimentional human face synthesis and
emotion generation in computer animation.
In the area of geometry modeling for computer graphics,
paticipanits proposed several novel approaches on efficient
mesh modeling. For inctance, Prof. Shiming Hu from Tsinghua
University presented a new skeleton-driven deformation
technique. A material-aware deformation approach was
proposed by the geometry computing group from Zhejiang
Univiersity, whose approach made a new progress in differntial
mesh procesing which is known as one of the hotest topics in
geometry modeling. A Taiwan research group leaded by Prof.
Bing-Yu Chen focused on discussing how to solve the
deformation transfer problem on carton animation. Shape
matching and analysis is another most attractive topic in CGI
2006. Wolfram von Funck, a Ph.D. cadinate from MPI,
Germany proposed a technique on extracting face model peice
directly from 3D mesh models. Using U-operator, a novel
solution on the 2D shape matching and retrieval was proposed
by a research group from University Macau of Science and
Technology which leaded by Prof Dongxu Qi. Subdivision
surfaces, which is regarded as a new gneration technique of
surface modeling, recieved quite a lot of attension. Researchers
from U.S., U.K., Hong Kong and Lebanon talked over
subdivision surface lofting, shadow rendering, optimization of
subdivision levels, and subdivision surface fitting.
Regarding for visualization and human-computer interaction,
the main discussion focus was influences and applications of
different types of contact and non-contact interaction device in
the conference. Lionel Dominjon et al. from French compared
three techniques to interact in large virtual environments using
haptic devices with limited workspace. The research group
from institute of computing technology, Chinese Academy of
Science, leaded by Prof. Guozhong Dai, exhibited their newest
progresses on gestures recognition and interaction. Moreover,
Spanish academicians, P. Morill et al. thoroughly analyzed
techniques for distributed virtual reality in a P2P network
environment.
