In this paper, we introduce a method of graphic offloading computing using a GPU virtualization technology in order to provide high demanding software like 3D software as an on-line software service. When the offloading software is executed on server's software virtualization environment, its graphic works are processed on a client's GPU using GPU virtualization, while on the other its data works are processed on server's CPU. To do that, we propose a method of rendering graphics information on client side GPU using API Remoting method. Also, we show the better performance than server based rendering method when we serve offloading software which include dynamical 3D graphics that display images are frequently changed through on-line. Moreover, we describe a method to virtualize offloading software by a process level and manage client's configuration information in order to decrease server's load when we provide software service to multiple clients.

Graphic User Interface has been playing a great role in giving people easy access of computer. The research of implementing graphic image on the computer display and inventing mouse were the threshold of GUI's birth in 1960s, and those were succeeded to developing the first GUI based-computer at the Xerox research center in 1970s. An education theory for the children and the visual metaphor of real life environment were adapted to implement GUI. They were continuously studied and tested in the beginning of creating the GUI concept and design method. In 1980s, the GUI concept and design method were generally applied to all personal computer development. Apple and Microsoft have led the commercialization of their GUI based-05, and also got their own positions in the market as GUI standards in 1990s. The first research for the GUI based-computer implementation in Xerox has established very clear concept and design methods. This GUI standards are evolving Into more convenient and natural ways in various computing environment and developing technologies these days.

I intended to establish Augmented Reality(AR) Museum of 3D Cyber Space where artists and graphic designers can freely create in user integrated environment. This study is aimed at building a sufficient and integrated production environment for artists and graphic designers who utilize three-dimensional simulation methods in integrated development environment(IDE). This study intends to build a 3D simulation engine and a creation module of augment reality of 3D cyber space in Android platform to help artists and graphic designers to freely perform their creation in IDE. Based on these designs, I produced exhibition rooms of National Museum of Contemporary Art in 3D virtual space in which artists and graphic designers can put the graphics they have created on display, conducted a user survey and conducted tasking to an Android smartphone.

A parametric boundary equation is established for the principal period-2 bulb in the cubic Mandelbrot set. Using its geometry, an efficient escape-time algorithm which reduces the construction time for the period-2 bulbs in the cubic Mandelbrot set is introduced and the implementation graphic results display the fascinating fractal beauty.

In this paper, a method measuring the reverberation time simultaneously on all of the audio frequency range was studied. The system developed in this study is composed of a pink noise generator, filter bank, and microcomputer with graphic display. In the experiment, reverbration time data measured by existing analog method and by the system were compared, and were almost same through the audio frequency. Based on the conclusion, the subject method has more convenience and accuracy with algorithm program development without existing problems and it was found out that this kind of method is widely available for many branches of room accoustics and architectual acoustics.

The purposes of this paper are to review the concept and system structure of computer graphics and to discuss the applicability of computer graphics technique as an analysis tool in transportation studies. To do this, several applications of computer graphics used for analyzing and solving transportation system problems were described and illustrated. The results indicate that computer graphics are found to be powerful aids to the analysis and design of transportation systems that typically involve large data bases and several interacting components. The results also indicate that computer graphics can be a powerful tool for aiding planner, decision maker and citizen in making it easier to explain and interpret information through mapping and graphic display.

An application-oriented approach to automatic pass schedule design in shape rolling was presented in this paper. The design approach and its related program are composed of several modules for input data, graphic display, data processing, calculation of design information, drawing of detailed pass shapes, database management and finite element analysis for design verification. The developed program was applied to automatic pass schedule design for a square-to-round bar shape rolling.

An FTCS is developed for the purpose of improving the reliability of a process control system. The proposed FTCS has capabilities of failure detection, back-up control, graphic display, and self-checking. Also the FTCS is combined with the process simulator to experiment in laboratory for the evaluation of performance of operation. The FTCS is applied to Thermal Power Plant .

This paper introduces the system AUTO-CUT for the automatic generation of NC tapes for wire-cut EDM (Electrodischarge Machining) parts. The information input to the system is the description of the part geometries, the tool motions and the cutting conditions etc. The system generates CLDATA. Also dynamic graphic display of the tool motions can be-performed on the screen.
