There can be three objectives why we apply 3D graphics in TV interface. First, inevitable usability. 3D space is the most inevitable way for product-user interaction deviating from the current aesthetic or technical purpose of use. Second, enhance emotional satisfaction by merging interface into real life. Beyond digilog(analog+digital), we wanted users to naturally use the interface as if they are using everyday objects. And in order to do this properly, we analyzed the behaviors of users how they use their everyday objects and then analyzed the attributes beyond each behavior. Third, capaticy for enourmous contents of the incorporated TV. The most efficient way to display enormous amounts of contents in a limited screen is 3D. And that 3D space gives us almost unlimited capacity in accepting contents. Now to conclude, using 3D graphics for TV interface has significance in many ways but the issue is how we can maintain the 3D effects while customizing them into real products.

The purpose of this study is to draw a distinction between general computer graphics courses and game development ones and to find out making various improvements in game graphics courses. In addition to general hand-drawing skills and computer graphics technology which are essential for the students who major in game graphics; however, the special classes should be required for them to comprehend the work process of game development and to produce the game graphics data. This necessity of the discriminative education is going to be an identification of game development department. Although loading game data onto a game engine and finding out the solution to problems of data is one of the excellent settlement for educating game graphics students, it is not possible to purchase the commercial game engine such as Quake or Lithtech and to analyze the commercial program libraries. For this reason, this research presents the replacement of commercial game engine with VRML97 for the academic purpose and shows what effect upon education will be. It is expected that the VRML97 can be a substitute of the game engine for the effectiveness of game graphics education with more active study and verification of game fields.

본 논문에서는 3차원 그래픽 데이터베이스를 위한 효과적인 질의 처리 시스템을 제안한다. 이 질의 처리 시스템은 3차원 그래픽 객체나 3차원 이미지 객체(이하 3D 객체)에 대한 모양 특징 기반(feature-based) 질의를 지원한다. 제안하는 시스템은 3D 객체 에 대한 특징 중 모양 모양에 초점을 맞춘다. 객체간의 유시도 검색을 위해 객체의 모양 특징은 단순화되고 추상화 되어 사용된다. 3D 객체 데이타베이스 구성을 위해 XML을 확장한 3DGML 시스템을 이용하고 질의 처리 언어로는 XML-QL을 이용한다. 본 논문에서 제안하는 질의 처리 시스템은 3D 객체를 포함한 멀티미디어 데이터의 효율적인 검색에 활용될 수 있으며 다양한 그래픽 응용 분이 등에서 활용될 수 있을 것이다.

“국내 3D 그래픽 기술은 게임부문에서는 세계적인 수준에 이른 것으로 보이지만 애니메이션에 있어서는 아직 발전단계에 있습니다. 3ds max 6는 이러한 점에서 국내 3D 그래픽 기술을 한 단계 업그레이드시켜줄 수 있는 계기가 될 것입니다. 특히 디자인 비쥬얼라이제이션 분야에서도 이번 신제품은 가장 적절한 해법이 되리라 믿습니다.” 한국어도비시스템즈 영업이사를 거쳐 한국디스크리트 사업본부장으로 자리를 옮긴지 3년째를 맞고 있는 채수호 본부장은 3ds max 시리즈가 3D 그래픽 분야에서 차지하는 비중은 약 50%에 이른다고 설명했다.

선박운항자의 인적사고 방지 및 운항 훈련을 위한 방안으로 선박 운항 시뮬레이터가 사용된다. 선박운항 시뮬레이터에서 실시간 3D 가시화 기술은 현실감 있는 직관적인 영상을 제공하여 피교육자에 인지력을 향상시켜 시뮬레이터의 교육 효과를 높이는 중요한 요소이다. 본 논문에서는 선박 운항 시뮬레이터 장착된 실시간 가시화 시스템의 확장성 및 독립성을 확보하기 위해서, 가시화 시스템의 상업용 그래픽 엔진을 공개형 그래픽 엔진으로 대체하기 위해서 수행된 실시간 3D 가시화 시스템의 설계 결과에 대해서 설명한다. 실시간 3D 가시화 시스템은 요소 기능, 그래픽 데이터 활용, 타 시스템과의 연동 측면에서 도출된 운용 요구사항들을 만족하도록 설계되었고 시스템의 확장성과 상호운용성의 확보도 고려하였다.

In real-time 3D Graphics, pipeline optimization is one of techniques enhancing rendering performance. Pipeline optimization is kind of buffer reordering problem, but it is NP-hard. Therefore techniques that is approximating optimal solution and suitable for real-time 3D graphics are needed. This paper analyze pattern of rendering states changing costs for real-time 3D graphics, and based on this, the algorithm that brings rendering states into line by changing costs is proposed. The proposed technique shows good performance enhancement when costs of some rendering states are much higher than others. Proposed technique shows 2.5 to 4 times better performance than non-ordering algorithm and becomes more faster when rendering costs of a state gets higher.

Game production education in a university is very important because it is the stage for completing a game education course as well as for determining a future of game industry. In order to perform various experience and creative learning, it should be able to effectively use a computer infrastructure representing the knowledge and information society for the purpose of obtaining and re-processing information necessary for game production through prediction of directions of game industry as well information technology. This research is focused on an effective game engine education for students whom want to become game graphics designers. The purpose of this study is to draw a lesson of game production utilizing game engines and it enables practice-focused class for game production. It also allows the class participant to manufacture prototypes without support from game programmers for their outcomes of works planned during the game production class. The theoretical background of game production compared and analyzed exemplary game engines. Based on the result, the study selected Unity 3D engine and conducted the research on the background where the Unity engine has been selected and its characteristics. In addition, this study provided an example of game production utilizing a game engine, and also described the details of actual realization. This study selected Torque3D with the Unity in order to identify the purpose of this study and efficiency of learning. Thus, the previous situation is that the class remained in making a game plan during the course of game production project and, students whose major is not game programming. Now, it is necessary for students to make many efforts to make a game in an active and positive attitude by utilizing a game engine beyond the previous method of class.
