  • Recently, computer graphics has made possible a close representation of the due diligence. But, prefer the feel of a 2D computer graphics. 2D computer graphics and compositing of 3D computer graphics have already been produced for a long time. But, the virtual 3D computer graphics application in 2D image or live-action have been used to effect expression of a 2D computer graphics. Recently, 2D computer graphics content is being expanded through the cartoons. In some cases increase the efficiency by making a 3D computer graphics on the camera angle or temporal and spatial part. Through practical work and want to present the proper direction.

  • These days computer graphics technology has been applied in diverse IT fields. Needs for computer graphics such as 3D Printer, Head Mount Display, VR & AR are growing rapidly. Computer graphics will be more specialized and demanding for graphics specialists will be also increased. However, serious mathematical background obstructs people to learning computer graphics. An efficient computer graphics learning system would be helpful for graphics experts training. By analyzing the graphics theory, we propose an educational software system with that students can effectively learn computer graphics. Our system focuses on theoretical objects of computer graphics and enhances accessibility and intuition using web and blocks.

  • 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.

  • In the field of computer graphics, rendering speed is one of the most important factors. Contemporary rendering is performed using 3D graphics systems with windowing system support. Since typical graphics systems, including OpenGL and the DirectX library, focus on the variety of graphics rendering features, the rendering process itself consists of many complicated operations. In contrast, early computer systems used direct manipulation of computer graphics hardware, and achieved simple and efficient graphics handling operations. We suggest an alternative method of accelerated 2D and 3D graphics output, based on directly accessing modern GPU hardware using the direct rendering manager (DRM) system. On the basis of this DRM support, we exchange the graphics instructions and graphics data directly, and achieve better performance than full 3D graphics systems. We present a prototype system for providing a set of simple 2D and 3D graphics primitives. Experimental results and their screen shots are included.

  • 본 논문은 색종이 리스트를 미리 생성하여 필요할 때마다 불러들여 찢어 붙이는 방법의 색종이 모자이크 렌더링 기법을 소개한다. 색종이 리스트는 색종이 이외에도 잡지와 같은 다양한 종이들을 미리 생성하여 사용할 수 있기 때문에 여러 가지 형태의 모자이크를 표현 할 수 있다는 장점을 가진다. 색종이 모자이크를 생성하기 위해서는 색종이 타일의 선택, 모양 결정, 그리고 배치의 3가지 과정을 거쳐야 한다. 먼저 색종이 타일을 붙일 위치에서 가장 알맞은 타일을 리스트로부터 선택하고, 적절한 모양으로 찢는다. 마지막으로 입력 영상의 특징(경계선 등)이 유지될 수 있도록 타일을 배치하여 최종 결과 영상을 생성한다.

  • 본 연구에서는 영상에 간단한 공간 필터를 적용하여 연필 해칭 효과를 갖는 영상을 만들어 내는 방법을 제안한다. 해칭 스타일의 톤 생성을 위하여 모션 블러링을 이용해서 입력 영상에 방향성을 주고, 샤프닝과 블러링으로 연필 해칭 효과를 만들어 낸다. 이렇게 만들어진 영상은 영상 전체에 같은 방향으로 해칭한 것 같은 효과를 가진다. 모션 블러링을 각기 다른 방향으로 적용한 영상들을 합성하면 크로스 해칭의 효과를 만들 수 있다. 여기에 소벨 필터를 사용해서 원본 영상의 에지를 검출해서 함께 합성하여 해칭을 이용한 연필화를 생성한다.

  • In this paper we describe a development of a multi user game using 3D graphics and multicasting. First, we represent a virtual reality world by 3D graphics technology. Next, we use computer communication technology for the purpose of interaction among multi users. As a result, multi users share 3D graphics objects and play games. The goal of this paper is a development of a system that enables multi users to play games sharing a virtual world represented by 3D graphics. We use the OpenInventor library and C++ language for 3D graphics scene representation, and IP multicasting protocols for computer communication. The system allows to use Polhemus Fastrak 3D input device that recognizes the 3D position and 3D orientation. As an example we present a game that demonstrates the effect of piano concert by multi piano players who are distributed in a computer network.
