In this paper, we propose a automated techniques for generating the gait animation of humanoid character model required in game applications. The proposed method can generate motion data of various styles with intuitive manipulation, and techniques for editing motion data are also proposed. In addition, we introduce an automated tool for gait animation of character model developed with the proposed method to verify the effectiveness of our method. The proposed method tan be successfully employed in motion authoring tools. In this paper, only the gait animation was considered. However, the proposed method can be applied to various motions and can be utilized as a motion engine that automatically generates proper motion according to the state of the character. The motion engine can express various behavior of the character without requiring motion data base which is usually employed in 3D online games.

The ratio of roles, involving characters created by 2D or 3D Graphic Technology, has risen within games, recent animations, movies and the educational sector. However, the "monster character" appears mainly in "Shanghai Ching" and Greek and Roman mythology. To receive worldwide accolade, it is time that we should use our games, movies and animations to present the history and spirit of Korea. I researched Korean myths so as to understand the characteristics a "Korean monster" would need to portray. This also allowed me to visualise the monster and realize the necessary manufacturing processes involved.

현재 게임제작에 많이 사용하고 있는 Unity 3D 게임 엔진은 다양한 플랫폼을 지원하고 있으며, 장점으로는 간단하고 저렴하게 개발할 수 있어 많은 개발자가 사용하는 엔진이다. 다양한 개발사 및 개인 개발자들도 많이 사용하는 만큼 Unity 3D 게임 엔진의 다양한 기능을 습득할 필요가 있다. 3인칭 게임인 Beyond eyes 라는 게임이 시각 장애인의 캐릭터를 컨셉으로 게임이 제작되어 다양한 시각적 효과를 사용하였다. 이러한 게임에서 감명받아 Unity 3D 게임 엔진의 여러 가지 기능과 참신한 아이디어를 접목하여 다양한 시각적 효과를 구현하였고, 그에 따른 개발 방법을 설명한다.

In domestic game market, the video game market is getting smaller and also decreasing funds and high level developers. So we need the software that can help us to make more realistic and high quality contents by non-expert developer in poor environments. In this paper, we selected global studio's animations which were scored good evaluation by public and critics as a well-made emotional expression that can convey the emotion properly. We selected movements that express emotions from the animation scripts by using Ekman's 6 basic emotions and Greimas' dynamic predicate, and then we had analyzed and categorized with the data. We also analyzed the movements for which data we needed to create specific movements to express emotions by using 'Animation Layer' that used in Unity's blending process. And suggest concept of the program that to create the emotional expression movements by using those analyzed data.

온라인 게임 서비스를 위해 캐릭터 외형 페인팅를 하기 위해서는 3D 인터렉티브 텍스쳐 페인팅를 사용한다. 3D 인터렉티브 텍스쳐 페인팅은 3차원 공간상에서 3D 모델 데이터의 표면에 직접 브러쉬를 이용하여 페인팅 하는 것을 말한다. 3D 인터렉티브 텍스쳐 페인팅을 구현하기 위해서는 매개변수화와 브러쉬 드로잉이 중요하다. 본 논문에서는 3D 공간상에서 평균값좌표를 이용하여 3D 모델의 표면 메쉬상에 텍스쳐 페인팅을 수행하는 효과적인 방법을 제안한다. 기존 연구가 가지고 있는 문제점은 반복적인 매개변수화의 과정과 그로 인한 해상도의 큰 변화이다. 이러한 반복적인 매개변수화 과정을 피하기 위하여 주어진 메쉬에 한 번의 전역적 매개변수화를 적용시키고, 3차원상의 메쉬에 직접적으로 페인팅 할 수 있는 인터페이스를 제공하였다. 결과적으로 2차원으로의 텍스쳐 수정 과정 및 렌더링 과정을 반복적으로 적용할 필요가 없게 되어 3차원 모델러에게는 매우 효율적인 방법을 제공할 수 있다.

All through the World, the Game Market has grown up speedily and the Game technology progress rapidly for the advancement of the computer technology and the increase of the number of PC in use. For in this thesis, we will research on a real-time 3D game engine technique that is the core of FPS(First Person Shooter) which apply a 3D virtual reality and deduce a production of contents. Finally we will comment on a direction in development of the game engine.

In the virtual space in which human imagination exists, a great deal of games and animation contents have been developed and shown. Games and animations are performing a role as an unrealistic representative, and creating abundant virtual culture with variety of human life. A representative, that is, a main character is being completed with external design, unique personality and ability, and action in the story. This study is expecting that a game character might develop into motion acting for emotional situation from the simple action. As giving a game character a role as a medium to express various circumstances and emotions, choosing motions from a pantomimist and applying them to 3D character, and expressed according to the motion acting. Motion acting is extended from the basic motion into the emotional phases such as joy, anger, sorrow and pleasure. The motion acting expressed from various viewpoints is suggested, as communicating clear message through emotional acting contrary to the symbolic language.

This paper aims to study whether the perspective of the character controlled by a player can affect the player on her moral decision. To this end we designed and developed Castaway, an interactive story using Unity3D game engine. The main story plot of Castaway is based on the trial 'R v Dudley and Stephens (also known as mignonette 1884) which occurred at 1884 in U.K. In Castaway, the player can choose either the accused or the victim, and then play the interactive story with the perspective of the chosen character. To investigate the relationship between the player's empathy to the player character and player's moral decision, we conducted a small-scale (n=10) pilot study. Results of the pilot study have shown that different perspectives can influence the player on her empathy to player character and her moral decision. In near future we plan to conduct a main study with more participants.

In this paper, we propose the method of manipulating the gaze direction of 3D FPS game's character by using eye gaze detection from the successive images captured by USB camera, which is attached beneath HMB. The proposed method is composed of 3 parts. At first, we detect user's pupil center by real-time image processing algorithm from the successive input images. In the second part of calibration, when the user gaze on the monitor plane, the geometric relationship between the gazing position of monitor and the detected position of pupil center is determined. In the last part, the final gaze position on the HMD monitor is tracked and the 3D view in game is controlled by the gaze position based on the calibration information. Experimental results show that our method can be used for the handicapped game player who cannot use his(or her) hand. Also, it can Increase the interest and the immersion by synchronizing the gaze direction of game player and the view direction of game character.

Today, video games created via 3D softwares become a core part of the essential the video game contents field because their properties that can produce more easier than 2D games and can save budget of contents makings. It is very important that reducing polygon counts of 3D characters and environments for Gaming optimization. We can formulate elaborate 3D game models with low polygon counting in virtue of technological advancements, and these technologies continue to evolve. In 2012, Pixar made public Open subdivision which is the new technology to make high quality 3D models with low polygons and distributed that via Open source verification. This paper will compare and analyze the characteristics, and merits and demerits of these various kinds of these skills(Mesh smooth, Turbo Smooth, Open subdivision) and will inquire which method is the most efficient one to make 3D video games.
