The flight simulator should be made like a actual flight. For the scene of sight, instrument should show the condition of flight and the pilot should catch the altitude, speed, pose and rate of lift of the airplane. The paper describes 3D flight visual training program of driving airplane in practice. It is for beginners using joystick in PC, implements airplane physical equations. And it uses rendering technology to implement vision parts of flying object.

Three-dimensional simulator for the ion implantation process is developed. The simulator based on an analytical model which would be a choice with high computational efficiency and accuracy. This is an important issue for the simulation of a numerous number of processing steps required in the fabrication of ULSI or GSI. The model can explain scattering and bulk channeling mechanism (1D). It can also explain depth dependent lateral diffusion effect(2D) and mask effect(3D). The model is consist of one-dimensional JPD(Joined Pearson Distribution) function and two-dimensional modified Gaussian functions. Final implanted profiles under typical mask structures such as hole, line and island structure are obtained with varying ion species.

Currently, aircraft and automobile simulator for training provides a variety of training by making hypothetical situation on a simulator installed on the ground currently. And the instructor maximizes the effectiveness of the training by monitoring training and instructing the required training. When trainees are boarding the aircraft or automobile. The Instructor in the ground is not able to monitoring aircraft, automobile. The assessment of the training is not easy after the end of the training. Therefore, it is difficult to provide high quality of education to the students. In this paper, simulation system is to develop the following. Collecting GPS and real-time information for aircraft, automobile $\grave{a}$implementing 3D simulation. Implementing current image of the aircraft or automobile in the screen by 3D real-time monitoring of training situation at the control center utilizing for training saving 3D video files analysis, evaluation on training after the end of the training.

This paper describes an effort to develop a simulator of Active Power Filter (APF) by three dimentional(3-D) space current co-ordinate. System current is represented by 3-D vector composed of three current components - active, reactive and distorted. %THD (%Total Harmonics Distortion) can be converted to height-angle of system current vector and power factor can be defined on 3-D space current co-ordinate without loss of generality. Current of APF and power system can be analyzed by 3-D visualization of current vector trajectory. So, the computer simulation results show that the proposed method by 3-D space current co-ordinate make up for disadvantages of performance evaluation on time / frequency domain.

비행시뮬레이터는 ICT 및 SW 응용분야에 속하는 기술로 항공기의 환경을 재현하는 시뮬레이션 환경을 제공한다. 시뮬레이터의 조종 장치인 일반적인 조이스틱을 대체한 기존 VR장비의 컨트롤러는 허공에 들고 조종하므로 정확하고 정교한 실제 항공기 조종에 사용하기에는 많은 문제점이 있다. 본 연구에서는 비행시뮬레이터와 VR분야에서 사용될 수 있는 가속도 센서와 진동 센서를 적용한 3D 조이스틱을 제안한다. 이를 위하여 3축 센싱과 정보를 표시하는 디스플레이 및 와이파이 통신을 위한 보드를 설계하고 유니티 기반의 가상 환경을 구현하여 적용 가능성을 확인하였다. 정상적으로 통신 인터페이스를 통하여 조종 장치가 동작하였고 게임 및 구현된 보드에서 확인한 센싱값이 일치함을 확인하였다. 연구의 결과물은 비행시뮬레이터 외에도 VR 및 다양한 메타버스 관련 콘텐츠에 사용될 수 있을 것으로 판단한다.

Recently the construction of simulation environment is an important issue in all fields. In case of the training for operating machines such as airplanes or spaceships which cause a huge cost, simulators could be helpful to reduce the costs and training efforts by simulating real situations. When people get a driver's license, too many trainees have to wait for their turns because of the limited number of cars and the small space of training sites. To solve this problem, we have designed and developed the basic design for the simulators. We suggest the Computer 3D Simulation Model for a driver's practice. The concept of this simulator is from a 3D Racing-game which suits for a driving exercise. We provide users with handle-controlled simulation settings to let users feel reality as if they drive in real through this simulator. We also use a 'force-feedback' system which gives handle vibration when users collide against obstacles or exceed lanes. Users can be absorbed in the simulation program and feel the sense of the real. This paper is the study about modeling the driving exercise model of 'computer 3D simulation', and producing and utilizing the simulator through this modeling.

In this paper, a server and client simulator for the web-based multi-view 3D image communication system is implemented by using the IEEE 1394 digital cameras, Intel Xeon server computer and Microsoft's DirectShow programming library. In the proposed system, two-view image is initially captured by using the IEEE 1394 stereo camera and then, this data is compressed through extraction of its disparity information in the Intel Xeon server computer and transmitted to the client system, in which multi-view images are generated through the intermediate views reconstruction method and finally display on the 3D display monitor. Through some experiments it is found that the proposed system can display 8-view image having a grey level of 8 bits with a frame rate of 15 fps.

Recently, the cylinder of the excavator is applied in the various environment. So, we need the development of the simulator for the excavator. The simulator has the effects of the decrease of the cost and improvement of the cylinder's performance. In this paper, we design the simulator for the excavator and makes an analysis of the dynamics and structure. The simulator was applied to the excavator's models of 10ton, 20ton and 30ton because we built the data base of a real excavator's cylinder of information in the experiment. And we used the FEM analysis for the comparative study on the characteristics.
