Systems for physically based fluid animation have developed rapidly in the visual special effects industry and can make very high quality images. However, in the real-time application fields such as computer game, the simulation speed is more critical issue than image quality. This paper presents a real-time method for animating fluid using programmable graphics pipeline. We show that once two key-frames are given, the technique can interactively generate a sequence of images changing from the source key-frame to the target.

본 연구에서는 게임 배경과 게임 캐릭터의 효과에 대해서 나타낸다. 먼저 3개의 캐릭터 이미지를 주 캐릭터 로 만들 이미지에 합성기법을 적용하여 캐릭터들을 합성한다. 합성하여 만든 캐릭터와 다른 캐릭터의 모양과 형태에 맞게 알맞은 배경 색상으로 만들고, 각 캐릭터의 크기, 원근, 모양, 색상에 따라 효과를 적용한다. 따라서 게임 콘텐츠를 제작하는데 정지 영상으로 표현하여 캐릭터 애니메이션과 장면에 맞는 사운드를 삽입하여 게임 콘텐츠로서 시각과 청각과 움직임이 있는 게임 캐릭터를 제작한다. 특히 배경색, 캐릭터의 번개 및 라이팅 효과색상 같은 것에 관심을 갖고 제작하여 앞으로 게임 콘텐츠의 배경과 캐릭터 효과를 제작하는데 모션그래픽을 이용하여 간단하게 제작 할 수 있음을 나타내었다.

동화는 사건의 흐름에 따라서 이야기를 진행시킨다. 그러나 독자인 어린이들의 관심을 지속적으로 유지하기 위하여 사건을 실제 순서와 다르게 배치해놓아 극적 효과를 꾀하는 경우가 많이 있다. 동화를 애니메이션으로 생성하는데 있어서 이러한 사건의 배치에 담긴 작가의 의도를 제대로 파악하는 것은 중요한 문제이다. 본 논문에서는 이처럼 사건의 흐름을 파악하고 이를 활용하기 위해서 다루어야 할 언어적 요소들에 대하여 살펴보고, 결합범주문법을 사용하여 동화에서 나타나는 시간 관계를 분석한다. 또한 각 시간 관계에 따라 애니메이션 효과를 높이기 위한 영상 기법을 제안하고 이를 이용하여 시간 관계를 재현하는 시스템을 설명한다.

가상현실 기술은 사용자가 스토리에 참여할 수 있으므로 상호작용을 갖는 인터랙티브 미디어 및 교육 콘텐츠로 활용하는 것에 장점이 있다. 가상현실 공간은 3D 공간으로 구성되며 가상환경에서 사용되는 3D 캐릭터들을 제작하기 위하여 일반적으로 3D 모델링과 키 프레임 기반의 애니메이션 기법이 사용된다. 이러한 과정들은 상대적으로 큰 비용과 많은 시간이 소요됨에 따라 저예산의 프로젝트에서는 가상현실 기술을 적용한 콘텐츠 제작을 어렵게 만든다. 본 논문은 2D 만화 이미지와 만화 스타일의 애니메이션을 활용하여 가상현실 콘텐츠 제작기법을 제안하고, 만화 형식의 가상현실 콘텐츠를 제작하여 연구를 진행하였다.

Animation are consist of consecutive various images, and there are figure and ground. The value of figure image as character in animation consider more significant than the background image, it can be detected many literature reviews on that subject. It, however, is also a critical element for completing animation, in reality, it is not found many academical achievements on this subject. The background images imply the information of environment and atmosphere, and elucidates where the story happen, therefore character move, talk and express themselves there. In terms of academic endeavour to extend the knowledge on animation, this paper is one of vital researches to be suggest on background image study. The main purpose of this study is to classify the background images in the ways of three categories such as painting concepts of concrete, semi-abstract, and abstract to camera concept of deep-focus, out-focus, and distortion. It is to instigate for the study of background images, in the practical view. And it will be utilizing the basic theories of cognitive psychology, painting and camera techniques, in the ways of It is analysed to frequency of use, reality, amount of information, perspective, and role of background image. This study is to provide a basic theory of visual classification on background image for practicing animations and researching on this subject.

The Contemporary animation style based on technology become various within some categories and genres as recreating the importance and meaning of many formalities. According to the variation of the contemporary animation style, The computer animation that has affected on continuous development of science and its following broad-band culture takes charge of the important position in producing the contemporary visual art. On this thesis, I will research < Ani-matrix > which has 9 episode each for the different Matrix world focused on its animation style. I will analyze their forms of expression into the both aspects of esthetics viewpoint technologically and film making style traditionally regarding to the matter of reality and reemergence on a viewpoint of a realistically esthetics. Also I will analyze mutual connection among the reinterpretation for the reality, philosophical message, and animation style within < Ani-Matrix> suggested by influence of Post-modernism. Thus, I intend to prospect the formation of animation style followed by its esthetics construction and effect on computer animation of the film genre.

Advances in computer technology have made it possible for educators to design and develop their own multimedia instructional materials using visuals such as animation. Although, it generally believed that the Mew attribute of computer animation facilitates student's foaming, there is still relatively little research regarding the way in which student benefit from multimedia instruction using 3-D animation. The purpose of this research was to examine and determine whether the use of 3-D computer generated images is an effective teaching device for hoping children to understand color theory, and enhancing the tractional methods. In this study, a 3-D computer generated presentation was creative and it demonstrated the mixing of primary color to obtain secondary color. Three research hypotheses were developed in this research. The first hypothesis stated that 3-D computer generated presentation will be an effective device for teaching color theory. The second was that the presentation will be eye-catching and it will hold the children's attention. The third was presentation would enhance the children's memory of color. Results of this study show that visualization technology and the use of 3-D graphics ends can be employed in the field of art education to increases a chi1d's understanding of color theory. Also, it was proved that teaching children through 3-D graphic is an highly effective teaching tool. Thus this research is a oontribution to both children's au education and the relatively new field of computer animation.

Works engraving enlightenment and ethnic identity by giving meaning and lesson to past events and great people against the past can be one of the good ideal art film contents. The animation reproduces the existing cultural archetypes, situation and history, when the 'Book of Kells' was produced, and the myths of the Kelts tribes. This thesis analyzes the history the kelts, traditional patterns and formative symbolism shown in , and studies the cultural preservation method unique to animation contents. In conclusion, the movie not only suggests a methodology that animation content is an effective way to preserve the culture and history of the native people, but also pursues the eternal, enlightening and teaching people for history.

As time spent in front of the computer screens increases, an increasing number of people are using natural landscapes or virtual aquariums as their desktop and screen saver that can provide them with mental comfort. A virtual aquarium is constructed by an animation work that creates a variety of fish that freely move in a random virtual underwater environment to analyze their movement. This paper suggests a method that constructs an immersive virtual aquarium, using fluid animation method that expresses changes of shape of fluid in real time and the Smart Fish technology which is capable of an interaction according to the diverse characteristics of virtual fish. The suggested method can be used in a virtual aquarium, aquarium screen saver, virtual fish-raising game, etc., which express diverse undersea environment.

3D keyframe animation is used widely in 3D graphics for real-time animation. This is a method that registers the animated key values in the important several frames among the entire frames and generates the rest frame by interpolator using the registered key values. This paper proposed the watermarking for 3D keyframe animation using PositionInterpolator. The proposed algorithm selects randomly the embedding meshes, which are transform nodes among the entire hierarchical structure. Then the watermark is embedded into keyValues of PositionInterpolator in selected transform node. Experimental results verified that the proposed algorithm has the robustness against geometrical attacks and timeline attacks.
