the 15th Pacific conference on computergraphics and Applications (Pacific graphics 2007), held in Maui, Hawaii, USA, between October 29 November 2, 2007, focused on computeraided geometric design. Pacific graphics is an annual international forum with a broad scope covering a diverse set of areas in computergraphics, including modeling, rendering, animation, simulation, image and video processing, and applications. the event focused on the presentation of papers in the area of geometric modeling. the papers presented in the event addressed geometric problems on various curve and surface representations. Four of these papers are concerned with geometric analysis of discrete triangular meshes, while three papers propose solutions to problems in modeling with smooth curves and surfaces.

As an important means of CAID, 3D graphics software plays a significant role in the current field of industrial design. Compared with traditional teaching methods, the application of 3D graphics software has brought profound changes in the firming process of students' design abilities. New problems are studied brought by 3D graphics software assisting design to traditional design education, and the solution is proposed. 3D graphics software should be more closely integrated with industrial design education. In the forming process of students' design abilities, the software must be made full use of to develop their creative designthinking. 3D graphics software must be developed and improved for the new mode of industrial design education. In the process of design education, appropriate time should be chosen to impart software knowledge. It enables students to improve design abilities to adapt to times development.

video games have been the subject of controversy due to the depiction causing addiction and even violent behavior. Although many studies undertaking the examination of video games and the gaming culture deny that games are addictive, a stereotype of the game player as addicted continues to catch on in various domains of academic studies and, with greater effect, in popular culture, news media and governmental rhetoric. the addicted gamers are seen as low-class, proto-violent addicted and dangerous kids, learning to express repressed anger and aggression, sociopathically isolated. In this essay, I am not trying to discuss the details of the arguments, but to discuss the reason why these arguments occurred: Why people denunciate video game addiction? Why addiction is conceived as bad to us?

Human figure modeling and animation has been one of the primary areas of research in computergraphics. the complexity of simulating the human body and its behavior is directly proportional to the complexity of the human body itself and is compounded by the vast number of movements it is capable of In this paper, a detailed survey on existing methods for human-body modeling and skin deformations is given.

Compared with traditional fixed Instruction set architecture (ISA) processor, configurable processors can reduce the total number of execution cycles dramatically because the instruction set customization permits a much closer fit of the processor to target application. At the same time, custom instruction can also improve the energy efficiency remarkably. However, ISA customization does not always bring power efficiency Instead, sometimes it even increase the power consumption. To address this issue, this paper distinguishes energy efficiency from power efficiency via time granularity. Furthermore, a method combining ISA customization with frequency and voltage scaling is proposed to achieve both favorable energy and power efficiency.

A novel CAD geometric variation approach is proposed for machining a complicated shape workpiece and lettering on a 3D free form surface or a plane by means of a 3-dof parallel machine tool. First, a simulation mechanism of a 3-dof 3-SPR parallel manipulator is created, and its workspace is constructed by means of the 3-SPR simulation mechanism. Second, the tool path guiding plane and the simulation mechanism of the 3-dof 3-SPR parallel machine tool are combined to form a whole simulation mechanism. third, the extension of the active legs and the position of the platform are solved automatically and can be visualized dynamically by means of the simulation mechanism. the simulation results are verified by the analytic results. the CAD geometric variation approach has the advantages of simple and straightforward, without any need of compiling program.

Texture atlas is widely used in many applications such as texture mapping, 3D Paint and illumination map texture synthesis etc. Several methods have been proposed for generating texture atlas, but most of them are not compact enough for some applications or require too much manual intervention. this paper presents a fully automatic BFD approach to generate compact texture atlas for triangular mesh models. Our main contribution is making some modifications to a piecewise mesh parameterization method to control the shape of charts by introducing a new local criterion, and developing a novel rectangle packing algorithm.

Wavelet method has been found to be very effective in treating geometric modeling due to its properties of localization both in time/spatial and frequency domains. We discuss how wavelet multiresolution techniques can be applied to free form feature (FFF) surface design, present one 2-stage CAD design approach combining feature concept and multiresolution representation. the approach proves that wavelet multiresolution technology is available for the extraction of FFF in the region of interest (ROI). the wavelet coefficients indicate the degree of detail in the solution;this makes feature/detail manipulation intuitive and convenient. Finally, an integrated framework of FFF surface design is given and discussed by an instance.
