The development of computer graphics leads to high value-added products, such as film, game contents, 3D animation. In realistic animation, it is impossible and inefficient to produce the movement of each objects as handwork to display the various behaviors of a lot of characters. So we need the techniques of the crowd animation which presents the movement of objects realistically and efficiently by calculating automatically. In this paper, we designed a modeler which generates the attitudes of objects in crowd behavior animation using information of 3D models. We developed an animation system for crowd behavior which was applied for animation, VR, or games.

This thesis is about to find possible opportunity to use Freeware Software in development and application of Digital Contents Creation software. There are 2D composition and Editing software, 3D production software and rendering Software as major part and motion capture, 3D Digitizing and other software operate in and out facilities in small part in Digital Contents Creation Software area. Most of Digital Contents Creation Software made by foreign countries such as USA and Canadian film, game and animation Digital Contents Creation industry, this causes higher production cost and lower profit of studios and usage of illegal copy of Digital Contents Creation Software as well. This thesis tried to present a solution to use Freeware Software in production process by researching and analyzing international and domestic software market and global trend of Freeware Software and present Freeware Software software in each production steps. This thesis include performance test of commercial render Freeware software.

This paper designed 3D animation in consideration of human characteristics to stimulate their interest and to be more understandable to them. It was also confirmed that, using the 3D animation contents, general people came to recognize the problem of environment pollution and developed desirable attitude and behavior for protecting the environment. Furthermore, this paper suggested the ruins original form restoration technique of the residential environment and the natural environment of Hanyang in the Joseon Dynasty period using the 3D virtual reality digital recovery techniques.

국내외로 수많은 게임개발자들이 이용하는 Unity 3D 엔진을 이용한 게임들을 제작 하였다. Unity 엔진이 많이 쓰이는 이유 중 하나는 복잡한 알고리즘을 코딩해야만 구현 할 수 있는 기능을 컴포넌트 형식으로 지원해줌으로써 개발을 좀 더 수월하게 진행할 수 있기 때문이다. 탈출 게임을 개발하려면 일단은 컨셉에 맞는 요소들을 만들어야 할 것이고 또한 탈출 게임의 기능들을 수행할 스크립트 구현을 하는 것 또한 매우 중요하다. 본 논문에서는 게임 엔진 내에 있는 기능들을 이용하여 탈출 개발 과정에 대해 소개한다.

Virtual Reality makes a virtual environment more realistic and, furthermore, it provides a variety of experiences which we cannot have in reality. A drastic growth of GPU performance and increase of computing capability make virtual environment more realistic than ever. One important element of constructing virtual environment is to animate 3D characters. Many researchers have been studying 3D characters animating and a myriad of methods have been proposed to make them more realistic. In this paper, we discuss the technologies and characteristics of 3D character animation. We believe that realistic characters in Virtual Reality will be applied to various fields: education, film and game industry, business and, particularly, medical area such as telemedicine, virtual surgery, etc.

Today, one of the most important reasons that 3D software becomes a core part of the essential tools in the video contents field like the movies, animation, CF, motion graphic, games and etc. is that they can save budget of contents makings and can produce better effects than conventional methods like miniature, matt painting, extra mobilization and etc. and can save time and have the merit that they are not limited in space. In this paper, I analyzed IK(Inverse kinematics) system characteristics for the efficient education of 3D character animation particularly most used of 3D applications which is now supposed to be nearly necessary elements in game, animation, movie and contents. And by analyzing merits and demerits of each tool on Bone, Character studio and Character Animation Toolkit, systems which are most used practically in the various Inverse kinematics tools, I showed the result of analyses about the fact that educating which of the above three Inverse Kinematics tools is helpful and beneficial for the students for the efficient education in the university where should teach much in the limited time

Domestic game companies are competitive in developing on-line 2D game contents. However, they have difficulties in maintaining the competitive edge in the area of on-line 3D game technologies owing to the limited funds and technologies. The 3D on-line game engine technologies we have intended to propose in this research are highly expected to be the key technologies ensuring the competitive edge over other countries. For this, we propose a full 3D online game engine that reflects the cutting edge technologies trend in the computer gaming industry. Our game engine is integrated with rendering and animation core technologies to visualize the game world, and provides stable network service through the Internet using server technologies.

In this research, we develop 3D online racing game to aid the comprehension about resource recycling, in the way of provoking children's interest and satisfying scientific curiosity, using 3D graphic editor and DirectX programming tool. This game is developed for children to experience the collection and classification procedure of recycling resources by only taking part in a game naturally, and to learn recycling-process contents produced using animation technique. Especially, we make this game to utilize it as an educational and public medium at home and abroad, and to interchange with foreign institutes, by offering korean version as well as english version. As a result, this game can be used as educational contents about resource recycling, because it is developed in the style that children can enjoy it directly.

This paper designed 3D animation in consideration of young children's characteristics to stimulate their interest and to be more understandable to them. It was also confirmed that, using the 3D animation contents, young children came to recognize the problem of environment pollution and developed desirable attitude and behavior for protecting the environment. Therefore, this paper suggested the proper environment education activity materials with our environment culture centered to enable teachers to do efficient and practical environment conservation education activities by forming close relationship between teachers and children's family.

The success of a three-dimensional blockbuster movie, AVARTA, brought an public attention on the expansion of three-dimensional computer applications, and it allows experts predict further hardware technology developments to support the such applications. Futhermore, an internet based infra structure and three-dimensional structure, third generation network community, advanced computer networks have influenced advancement in computer technology within the 3D game industry and the spread of 2D computer animation technologies. This advancement of computer technologies allow the industry to overcome a limitation of generating cultural design contexts existed within 2D network community. However, despite of the expansion of 2D and 3D computer technologies, a limitation of analysing designers' intentions on morphology of digital contents and user interface still exists. Therefore, the purpose of this study is to analyze (1) present conditions of the 3D industry and (2) protocols of designers' cognitive design processes based on their design communication, contents, and tools. Analysis was conducted based on literature reviews and case precedent analyses. For the analysis, a 2D Avarta sketch character was designed and then applied into a 3D game system. Observations how designers solve cultural problem within the structure via Avarta were conducted. Outcomes were then coded for further analysis.
