In 1970s, Computer Graphics of still and geometry changed computer Animation of image, and Computer Animation has diversely been used in movie, TV, fashion, sports, education, basic science, medical science, etc. by the development of LSI technology and the large size of computer in 1980s. Since Computer Animation was first used by movie of Futureworld in 1973, we easily experienced the essence of Computer Animation made of the Little Mermaid. Beauty and the Beast, the Lion King, Aladdin, etc. in Disney Animation and Terminator. Jurassic Park, the Mask, etc. in movie. And in other countries that have got the diversely special effect and knowhow in technology are effectively using the Computer Animation now. What situation we Korea are in now, if we compare the Computer Animation with that of other country using the progressive movie\ulcorner Although we first producted the movie title of Ticket, 10years ago, we have rarely been used it in movie, yet. Therefore, we know that it is very important for us to examine the historical and technical side for the purpose of overcoming the technological gap.

It is true that the new development in digital technology has Influenced on the definition of animation like it did on the other fields of an, but this doesnt mean this development drastically changes the traditional concept and replaces it with innovative new one. The more the technology is being developed, the mon it needs traditional base that can lead it to what it originally should be. As an example, computer animation companies are constantly seeking for people who have traditional animation background rather than well-trained computer oriented artists. This means digital technology will be no more a technological threat to the people who has traditional animation background. Consequently, when considering the extended concept caused by this new technology, we have to find its base on the traditional animation concept. Since we dont have any fundamental base in traditional animation and technological base in computer animation, we should consider those in advanced countries as a standard. However, in these days, there is a tendency to worship the words themselves such as "digital revolution", "information technology" etc., not the basics behind them. We cannot expect any achievement with this in mind. This study might be a short cut to the students and animators who want to learn and approach computer animation in a right wav.

자연스러운 얼굴 애니메이션 생성은 캐릭터 애니메이션 분야에서 중요한 문제이다. 지금까지 얼굴 애니메이션은 3차원 모델링 프로그램을 이용한 전문 애니메이터들의 수작업을 통해 생성되거나, 필요한 움직임 데이터를 직접 동작 캡쳐함으로써 만들어 왔다. 그러나 이러한 방식은 일반 사용자가 쉽게 접근 할 수 없으며 많은 시간과 비용을 요구한다는 단점이 있다. 본 연구에서는 실제에 가깝고 자연스러운 얼굴애니메이션을 만들기 위해, 누구나 쉽게 사용할 수 있는 직관적인 방식의 스케치 인터페이스를 이용하고자 한다. 이를 통해 키-프레임을 생성하는 시스템을 구축하고, 얼굴 캡쳐를 통하여 얻은 데이터로부터 추출한 얼굴 표정간의 전이 정보를 이용하여 키-프레임을 보간하는 방식을 제안한다. 본 시스템은 전문 애니메이터가 아닌 일반 사용자도 쉽고 빠르게 다양한 감점을 표출하며, 동시에 말하는 얼굴 애니메이션을 만들 수 있도록 한다.

In this paper, we present an animation sketching system using a two layered approach. Animation sketching is a popular technique to create informal animations but it is often suffered by the low-quality output due to a trade-off between convenience and complexity. Our aim is to support sketching practical animation scenes easily and fast while not complicating the simple sketching interface. The key idea is to combine two conceptual stop motion layers, a whiteboard and cutout animation layer, in a seamless interface. As a background, the whiteboard animation layer handles stroke-oriented objects, while the cutout animation layer takes charge of transform-oriented objects. We found that this approach enables users to express more complicated animation fast while still maintaining a concise sketching interface. We demonstrate the usability and flexibility through resulting animations from user experiments.

컴퓨터애니메이션은 영상, 음향, 기획, 아이디어를 활용할 수 있는 종합예술이다. 국내의 기술은 다른 나라에 비해 결코 뒤지지 않지만 창의력이나 내용면에서 아직 뒤쳐진다는 점을 감안하여 본 논문은 기술보다는 기획단계의 중요성을 고지하고 형식에 얽매이지 않는 자기만의 애니메이션을 제작할 수 있는 나레이티브 애니메이션을 소개하고자 한다. 디지털 애니메이션 산업에서 성공적인 작업은 전문적인 기술 그 이 상을 요구한다. 즉, 창의적인 통제, 경의로운 감각, 무한한 상상력을 필요로 한다. 비길바 없는 이 실무의 프로그램은 전통적이고 창의적이고 정통한 기술을 아울러 가지고 소프트웨어 기술자가 아닌 디지털 아티스트를 계발해야 한다. 특히 3D애니메이션과 게임에만 치중한 요즘 나레이티브 애니메이션의 특성을 인식하여 새로운 형식 질 높은 애니메이션 제작이 필요하다고 본다. 따라서 본 논문은 디지털 애니메이션 교육에 지표를 제시함으로써 많은 도움을 줄 것으로 기대된다.

The world being made by computers showing great expanses and complex and various expression provides not simply communication places but also a new civilization and a new creative world. Among these, 3D computer graphics, 3D animation and virtual reality technology wore sublimated as a new culture and a new genre of art by joining graphic design and computer engineering. In this study, I tried to make a diagnosis of possibilities, limits and differences of expression in the area of virtual reality computer graphics animation as a comparison between camera action, angle of actual still camera and film camera and virtual software for 3D computer graphics software - Maya, XSI, Softimage3D.

Unity is a powerful game engine that can be used to create 2D or 3D content. The current study focuses on the use of Unity for 3D computer animations, covering the strengths, basic concepts and tools for creating and integrating 3D animations in Unity, including the use of keyframe animation, animation controllers, and blend trees. Also covering advanced topics such as skeletal animation, procedural animation and their applications in games, simulations, and other interactive media. Case studies that showcase the potential of Unity for 3D animation will be analyzed and discussed taking in the quality of visuals and the receptance by the public in general.

In this study, we study the development and control of motion of 3D character animation and discuss the development direction of technology. Character animation has been developed as a data-based method and a physics-based method. The animation generation technique based on the keyframe method has been made possible by the development of the hardware technology, and the motion capture device has been used. Various techniques for effectively editing the motion data have appeared. At the same time, animation techniques based on physics have emerged, which realistically generate the motion of the character by physically optimized numerical computation. Recently, animation techniques using machine learning have shown new possibilities for creating characters that can be controlled by the user in real time and are expected to be developed in the future.

Fluid is an effective element in computer animation. Recently, the techniques from CFD have been actively applied to CG production. In this paper, we describe our fluid animation system which implements a variety of established simulation and rendering methods. We also explain our new techniques such as chemical reaction and hardware-assisted fluid animation that are being developed to enhance the features of our software system.
