본 논문에서는 미리 모델링된 실객체에 대한 3차원 모델을 변형하면서 애니메이션을 정의하고, 실사 객체를 추적하면서 카메라 뷰 상의 실사 객체에 애니메이션을 적용하는 방법을 제안한다. 애니메이션 정의는 라플라시안 기반 메쉬 변형 방법으로 3차원 모델을 변형시키며 키프레임을 지정함으로써 이루어진다. 정의된 애니메이션은 실제 환경에서 추적된 실사 객체의 영상으로부터 모델에 텍스처를 입힌 뒤, 카메라 포즈를 이용하여 객체 위치에 객체 모델을 렌더링할 때 적용된다. 제안된 방법을 통해 사용자가 원하는 대로 실제 환경에 대한 카메라 뷰 상에서 실사 객체가 변형되는 모습을 용이하게 보여줄 수 있다.

최근 컴퓨터 그래픽스 분야에서는 3차원 애니메이션에 대한 연구가 활발히 이루어지고 있다. 3차원 애니메이션에서 중요한 연구 분야 중 하나가 인간을 애니메이션 하는 것이다. 음함수 곡면 모델은 3D 캐릭터나 유체 등과 같은 복잡한 곡면으로 이루어진 객체들에 대한 3D 모델링이 용이하고 적은 양의 데이터로 다양한 형태의 곡면을 표현할 수 있다. 본 논문에서는 음함수 프리미티브를 이용한 얼굴 모델 생성 방법을 제안한다.

This study describes the humanistic perspective inherent in Korean Buddhism. It is based on a narrative of the establishment of Haeinsa Temple, which is one of the three major Korean traditional temples, and represents the heritage of Korean Buddhism. With this narrative, we developed and implemented mobile content for Android devices titled "Treasures from the Palace of the Dragon King". Its scenario, which is a folktale of the establishment of the Haeinsa Temple, was created using A.J. Greimas' Actantial model as the research method. As a result, the content developed by the reconstruction of the scenario consists of mini-games and animations offering an intuitive user experience (UX), which is implemented in a compound E-BOOK for mobile devices. We aim to promote Korea's traditional culture throughout the world, using this content as a starting point for the future.

본 논문에서는 웹 응용에서 jQuery를 이용한 사용자 인터랙션을 설계하고 구현하는 방법들을 제안하였다. 스마트 기기의 컴퓨팅 능력이 향상되면서 웹 응용 기술이 보편화되고 다양화되었다. 이로 인해 주목받는 웹 기술로서 JavaScript가 있고, 세계적으로 가장 많이 쓰이는 JavaScript 프레임워크가 jQuery이다. jQuery의 기본 문법과 확장성 및 플러그인에 대해 간단히 서술하였다. 사용자 인터랙션과 애니메이션들을 분류하였고, 이를 구현할 수 있는 방법을 서술하였다.

This article analyzes the background representation of 3D animation and look at what its proper background expression. With the development of computer graphics technology, the background of the 3D animations can be expressed as The actual background. In contrast, "The Smurfs" which was released recently was created to take the actual background. However, 3D animation with real background is not appropriate in terms of creative expression space in the main role of the animation. In this Study, we analyze the character and background of the animation made in 3D graphics. Based on this, we propose a correct representation of 3D animation background.

This study recognizes the narrative of the movie as a semiotic system and proposes a structured storytelling analysis model through theoretical basis and empirical analysis. It classifies as 'Narrative 17 Process' which considers the narrative of successful 11 animations as a continuous process of formal structure. It extract the paradigmatic sub-narrative units(NU) centered on the act of the character in each process. The structural pattern of the story types are extracted by comparing and analyzing with 5 NU analysis elements presented in this study. As a result, the 4 story types were consistently classified by the SSD distance value. Therefore, this study propose a storytelling analysis model that can be effectively applied to scenarios and narrative composition stages of movie production.

We are developing a simple low-cost wind velocity sensor based on small microphones. The sensor system consists of 4 microphones covered with specially shaped wind screens, 4 pre-amplifiers that respond to low frequency, and a commercial sound interface with multi channel inputs. In this paper, we first present the principle of the sensor, i.e., technique to successfully suppress the influence of external noise existing in the environment in order to determine the wind velocity and the wind direction from the output from a microphone. Then, we present an application for generating realistic motions of a virtual tree swaying in real wind. Although the current sensor outputs significant leaps in a measured sequence of directions, the interactive animations demonstrate that it is usable for such applications, if we could reduce the leaps to some degree.

In the multi-purpose lathe, the design of tilting turret slide system has an important and critical role to enhance the accuracy of the machining process. Tilting turret unit is traveled by 3-axis slide systems. There is a need to design this part very carefully. In this research, the 3-axis slide system with tilting turret unit is researched with two approaches; The first is that 3-axis slide system is modeled and simulated using ADAMS software. The dynamic behavior of this system is visualized by data graphs and dynamic animations. The second is that the slide system is analyzed with the aspect of stress distribution. The slide system is modeled and displayed by PATRAN and analyzed by NASTRAN. The analysis of strain and stress distribution in the each node is prompted and visualized in the computer. The first step of virtual prototype which makes it possible to design economically and effectively is developed.

Recently, the importance of participating in classes activity and cultivating student's thinking ability is emphasized in the mathematics education society. Teachers are demanded to change their teaching style centered pencile-and paper into using the variety instructional aids, such as calculator, video tape, computer, ohp, and projector, etc. In this paper, we search for the mathematica's function and the method that apply mathematical to the secondary school mathematics. Mathematical has many functions: calculator, algebra, graphics, animations, programing, notebook. We find that mathematica can be applied to the graph of function, the understand of simultaneous equations, the graph of trigonometry function, the calculation of limit, the computation of areas as limits, the derivative of a function and tangent line, a solid figure, and others in secondary school mathematics.

The purpose of this research is to develop the multimedia contents for the subject . is the subject to understand and analyze the characteristics of the textile materials and to be putting the key point to utilize the textile materials as the fashion materials. 1 developed the contents using multimedia system standing on the basis of Internet. The developed contents were organized to induce the interest. The sounds, pictures. computer graphics, animations, text, AOD and AOD etc. were utilized in these contents. These contents were consisted of preview, restudy, and the feedback through question. These contents can be executed directly in Web browser through Internet. Address is http://web.cnu.ac.kr/-fabric. Ⅰ applied this multimedia contents to actual class. It was utilized much more than textbook and it was turned out to be efficient in the experiment class.
