The establishment of a production pipeline imported 30 computer graphics is suggested in this paper to improve the efficiency of existing production pipeline of clay animation. The point is that the process of building clay characters that remains labor intensive among the existing procedures is replaced by the process of creating computer generated characters. In order to create characters out of clay by means of 30 computer graphics, a diffuse map and displacement map are made of an oil-based clay according to the UVW coordination of polygon modeling, which is the same color and kind of clay used to make a clay character. In addition, a panoramic HDRI recording system is developed to record the lighting information of shooting environment for miniature sets, which is imported in 3D computer graphic tools as digital light source. On account of the new production pipeline, a hyper realistic rendering image can be produced, and at the same time it improves the traditional pipeline of stop motion animation that is know-how based procedure of a complete artist by the engineering approach to the automatic process.

ZSphere of ZBrush can be added to the screen, and most of all, added to the existing ZSphere as mobile geometrical objects. For example, legs can be produced out of the globoid in the progress of an intermediate step. characters with multiple limbs can be produced easily in this way. With Zsphere, several Child Spheres can be produced out of single Sphere, then these can be parents spheres, and can connect other Child Spheres. In this paper, by making each form through these processes, 3D characters were modeled to shape easily and rapidly. Since 3D objects can be added, rotated, and moved, they can interact smoothly with Z-depth of campus. To place these objects on the screen, paint, build fixed perspective image, smerge pixols and transform 3D objects, diverse transforming tools and sculpturing tools were used. The characters were designed in the way that first, the finished 3D characters were transformed into poly, then each side was restructured rapidly with Topology.

본 논문에서는 IK 리깅을 이용한 캐릭터 콘텐츠 영상 제작을 제안한다. IK 콘텐츠를 2D와 3D로 제작할 수 있는데 본 연구에서는 2D로 캐릭터의 이미지를 레이어로 제작하고, IK의 bone은 스크립트로 생성하였다. 따라서 인체의 각 관절에 해당하는 부위에 리깅을 부여하여 자유로운 캐릭터를 제작하였고, 이러한 캐릭터의 제작은 모션 캡처 제작비용에 비해서 상당히 비용부담이 적은 경제성을 나타내고, 다양한 영역에서 활용 할 수 있다고 사료한다.

본 논문에서는 3D 캐릭터의 애니메이션을 제작하기에 앞서 kinect를 활용하여 캐릭터의 동작을 모션캡처를 통해 쉽게 제작하는 방법을 다룬다. 또한 제작된 캐릭터 애니메이션을 md2포맷으로 export하고 안드로이드 환경의 OpenGL을 활용하여 재생하는 기술을 제안하고 이를 이용하여 향후 스마트폰 증강현실에서 도우미로서 소프트웨어 로봇 또는 에이전트의 다양한 감성 행동을 제작하고자 한다.

인터넷 기술의 발전으로 온라인 가상 환경에서 3D 캐릭터를 통해 가상의 공간에서 현실로 넘나들고자 하는 욕구가 증대되고 있다. 3D 캐릭터를 통해 인간은 상상할 수 있는 모든 세계를 넘나들고, 실제 세계에서 실현이 불가능한 것도 가능하게 해주는 대리 역할을 한다. 더욱이 인터넷 상에서의 3D 게임이나 가상현실등의 증가로 인해 현실세계에 존재하는 물체들에 근접하게 모델링하기 위한 3D 캐릭터 애니메이션으로 관심이 쏠리고 있다. 본 논문에서는 3차원 객체를 높은 품질로 표현하기 위해서 새로운 framework을 적용한다. 다양하고 자연스러운 형태의 표현을 위해 Web3D 자료 형태인 VRML과 XML을 이용하여 3차원 Humanoid의 모델링과 애니메이션 기법을 제안하고 Simulation을 통해 타당성을 검증한다.

The 3D animation is the trend of more and more as the years go by. 2016 works "red soil" of the works through the analysis of the new changes, and also in the interest of those factors, which play an important role, how to performance in the appropriate way of expression. according to the focus of work in the process of modeling design of meaning and symbol and character, action and expression of the meaning of understanding and appreciation of the works, the meaning of double the fun.

창의적인 표현 이전에 무엇을 인식(認識)해야 하는가! 쉽게 생각하는 캐릭터모델링과 셋업(STE-UP) 과정이 몇 가지 옵션(Option)에 의하여 생성되는 것은 아니다. 애니메이션 제작에 따른 캐릭터 설정 배경, 인체구조와 모델링과의 관계, 인체구조와 애니메이션의 연관성 등에 대한 인식의 이해를 통해야 한다. 이러한 인식 속에서 3D 캐릭터애니메이션셋업(SET-UP)을 위한 기초인식과 기술을 통하여 원칙적인 이해에 근거하여 효율적, 효과적인 3D애니메이션 제작을 하기 위한 몇 가지 제안(提案)을 한다.

There has been the rapid change of paradigm with the overflow of terms related to computers such as information, digital, cyber, virtual world and the change of time concept on the ground that it is common to change the world into virtual time. This study is about cybercharacters working in air-broadcasting with rapidly-developing internet, The cybercharacters including 3D animation developed from 2D animation are know to be manufactured with use of electronic mediun and computers and to exist in electronics. Though the emergence of the cybercharacters has a lot of gflnetic roots according to their objectives, they have in common that they are made by 3D graphics and they work in the virtual space, The great traits of the cybercharaters lie in the extension of interfacial function and ecological growth. In the cyberspace the interface, the meeting point between a computer and its users is the most important, The cybercharacters as medium providing new ruman interface become effective with growing interest in virtual reality, The cybercharacters also keep the ecological traits, They can also bring about added value with infusion of image and development of the network, These cybercharacters can also play the important parts in the continually developing cyberspace, The successful birth of the cybercharacter are based on, the technological power. assistance of fund and the ctrltural background, The information-entertainment of the cybercharacters functions well with the accompinimene of these three things, The cybercharacters can make a subject which keeps single issue as a central point of the virtual realty, The cybercharacters can also be connected with equity of "Korean knowledge information society" in the cultural rule of the internet and sociocul tural identity, identity.

In this paper we describe the method of controlling the animation of 3D characters according to ISO/IEC 19774 (H-Anim) specification, which has been released by Wed3D Consortium and ISO/IEC SC24 WG6. The animation structure of the H-Anim character can be defined and modified in our H-Anim editor program. Our H-Anim animator generates the character's motion automatically according to the input of motion parameters at the character's joints interactively. This paper is focused on the development of a motion generation tool for human-like characters defined by H-Anim structures.
