의료영상의 크기가 커짐에 따라 처리해야 할 데이터량이 많아졌다. 또한 점점 더 많은 사람들이 빠른 3차원 가시화 결과를 기대한다. 하지만 이전에 제시된 많은 방법들은 실시간 응답 결과를 기대하기는 힘들다. 본 논문은 하드웨어를 이용하여 의료영상을 빠른 속도로 3차원 가시화하는 방법과 그 구현 결과에 대해 기술한다. 구현에 있어 자바를 이용함으로써 플랫폼 독립적이며 OpenGL을 기반으로 한 자바 3D API를 사용함으로써 쉽고 빠르게 3차원 가시화 결과를 디스플레이할 수 있다.

In this study, an integrated 3D modeling and rendering system dealing with 3D urban landscape features such as terrain, building, road and user-defined geometric ones was designed and implemented using $OPENGL\;{|}\;ES$ (Embedded System) API for mobile devices of PDA. In this system, the authoring functions are composed of several parts handling urban landscape features: vertex-based geometry modeling, editing and manipulating 3D landscape objects, generating geometrically complex type features with attributes for 3D objects, and texture mapping of complex types using image library. It is a kind of feature-based system, linked with 3D geo-based spatial feature attributes. As for the rendering process, some functions are provided: optimizing of integrated multiple 3D landscape objects, and rendering of texture-mapped 3D landscape objects. By the active-synchronized process among desktop system, OPENGL-based 3D visualization system, and mobile system, it is possible to transfer and disseminate 3D feature models through both systems. In this mobile 3D urban processing system, the main graphical user interface and core components is implemented under EVC 4.0 MFC and tested at PDA running on windows mobile and Pocket Pc. It is expected that the mobile 3D geo-spatial information systems supporting registration, modeling, and rendering functions can be effectively utilized for real time 3D urban planning and 3D mobile mapping on the site.

Shader architecture is one of the fastest growing fields in the ever advancing 3D graphics, and massive amounts of Ideas and technologies are being introduced to the market continuously. In this paper, we present a flexible cycle-accurate simulation environment to accelerate and alleviate the process of developing and verifying these ideas and technologies. Combination of 3D graphics API and hardware simulator allows OpenGL applications to be emulated off-the-shelf for a given shader micro-architecture. Easily modified parameters allow the simulation environment to be tailored to specific demands or requirements.

As make a simulator including user interface functions like start & stop, load parameters, record and save, view 3D display has a real-like length and numerical value of sizes, represent real-shape of inner and outer part of robot, make the possible fast and slow selective observation as a adjust a step, receiving the images through the image device which attached in robot, so make a motion tester simulator of humanoid robot which coded by windows based GUI(Graphic User Interface) program with a MMI(Man Machine Interface) function that user can watch the environment which included robot and use a images. For implement this, we use a design data that converted data which made by use a CAD for Laser RP(Rapid Prototyping) progress into C coding for simulator programming. Using OpenGL, an API of graphic, it has a efficiency and detail of graphic operation. To make and test animation data, it has the option of save and resume in animation.

An integrated single-wafer processing tool, composed of multiple single wafer processing modules, transfer robots, and load locks, has complex routing sequences, and often has critical post-processing residency constraints. Scheduling of these tools is an intricate problem, and testing schedulers with actual tools requires too much time and cost. The Single Wafer Processor (SWP) simulator presented in this paper is to validate an on-line scheduler, and evaluate performance of integrated single-wafer processing tools before the scheduler is actually deployed into real systems. The data transfer between the scheduler and the simulator is carried out with TCP/IP communication using messages and files. The developed simulator consists of six modules, i.e., GUI (Graphic User Interface), emulators, execution system, module managers, analyzer, and 3D animator. The overall framework is built using Microsoft Visual C++, and the animator is embodied using OpenGL API (Application Programming Interface).
