3D 게임 엔진 중 그래픽 엔진이 차지하는 중요도는 다른 엔진들보다 월등히 높다. 그래픽 엔진에는 여러 가지 필요한 요소들이 들어가는데, 지형을 만들어내는 것 역시 캐릭터를 제작하는 것만큼이나 중요한 역할을 한다. 3D 지형이 좀더 현실과 흡사하기 위해서는 실세계와 유사한 가상의 세계를 만들어야 한다. 3D 지형을 만드는 방법은 여러 가지가 있으나 자신이 원하는 지형을 직접 만들어서 이를 3차원으로 바꿔서 게임 엔진에서 사용할 수 있고, 또한 게임 엔진 내부에서의 최적화를 위해서는 가장 기본적으로 쓰이는 그레이 스케일 이미지를 사용한 높이 맵으로 지형을 생성하는 게 유리하기 때문에 본 논문에서는 그레이 스케일 이미지를 이용한 지형생성기를 개발한다.

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.

Graphical expressions are continuously improving, spurred by the astonishing growth of the game technology industry. Despite such improvements, users are still demanding a more natural gaming environment and true reflections of human emotions. In real life, people can read a person's moods from facial color and expression. Hence, interactive facial colors in game characters provide a deeper level of reality. In this paper we propose a facial color adaptive technique, which is a combination of an emotional model based on human emotion theory, emotional expression pattern using colors of animation contents, and emotional reaction speed function based on human personality theory, as opposed to past methods that expressed emotion through blood flow, pulse, or skin temperature. Experiments show this of expression of the Facial Color Model based on facial color adoptive technique and expression of the animation contents is effective in conveying character emotions. Moreover, the proposed Facial Color Adaptive Technique can be applied not only to 2D games, but to 3D games as well.

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.

Practical use degree of Motion Capture technology is low in korea game market which did growth of MMORPG putting first. However, that is dance game or FPS, sports game genre is magnified. Therefore, practical use degree of Motion Capture technology is increasing. And, need various research to take advantage of Motion Capture technology effectively. Studied 3D game character animation manufacture pipe line for it. Characteristic of this manufacture pipe line is work classification, correction of two times, Biped format all-in-one to progress Motion Capture technology and keyframe-animation work at the same time. Also, manufacture pipe line that is consisted of this constituent has economic performance, extensity, systemicity.

To improve the sense of unity between game players and game world avatars, we propose a method to measure game player's physical status and manipulate game character appearances and behavior using the measurements. To measure the status, we implemented a hardware module that perceive the body temperature. We implemented a 3D horror game whose game space is a common subway space ordinarily encountered in daily life so that ordinary people can easily get used to the game environment. The experiments of applying the measurement data from the game player to the game world avatar shows that the player's physical status can be effectively utilized to improve the sense of reality in gameplay.

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.

Rapid technology growth of hardware have brought about development and expansion of various digital motion pictured information including 3-Dimension. 3D digital techniques can be used to be diversity in Animation, Virtual-Reality, Movie, Advertisement, Game and so on. 3D characters in digital motion picture take charge of the core as to communicate emotions and information to users through sounds, facial expression and characteristic motions. Concerns about 3D motion and facial expression is getting higher with extension of frequency in use and range about 3D character design. In this study, the facial expression can be used as a effective method about implicit emotions will be studied and research 3D character's facial expressions and muscles movement which are based on human anatomy and then try to find effective method of facial expression. Finally, also, study the difference and distinguishing between 2D and 3D character through the preceding study what I have researched before.

오늘날 3D 캐릭터 애니메이션은 실사영화, 애니메이션, 게임, 광고 등 대다수의 영상물에서 쉽게 접할 수 있다. 캐릭터의 부드러운 움직임은 모션캡쳐(Motion Capture)나 숙련된 애니메이터의 키 프레임(Key Frame) 작업의 결과물일 것이다. 이런 작업들은 고가의 장비나 많은 인력을 요구하고 완성된 결과물은 수정하거나 효과를 주기가 힘들다. 본 연구에서는 3D Studio MAX Script를 이용한 삼차원 회전 값의 연산으로 바이페드(Biped)의 포즈나 애니메이션을 합성하고 보다 사실적인 합성을 위한 방법을 제시하고자 한다.
