게임 애니메이션을 위해 100명이 넘는 다양한 캐릭터를 만들어야 할 때 처음부터 모든 것을 해내기는 불가능하다. 또한 언제나 주어진 시간은 부족하다. 이런 상황을 극복하기 위해 예술적 표현 기술인 '마야(Maya)'를 통해 시간을 효과적으로 이용할 수 있는 몇가지 방법을 소개한다. 시험 방식과 MEL단순화 방법, 실시간 애니메이션 과정에 관한 기술적 세부사항이다. 이런 방법을 통해 제작팀은 제작시간을 줄이고 예술적 목표를 달성할 수 있을 것이다.

As information technology used for simulation and virtual reality developed, there is a growing interest in animation technologies which will effectively deliver simulation results to users. Various efforts have been made to improve animation performance, like playback quality and speed, input-output speed and storage space reduction. However, earlier studies generally focused on image compression frame by frame. To significantly improve storage space and playback speed, animation data should be vectorized. Also, spatial and temporal duplication have to be removed. In this study, animation data structure was improved fundamentally through establishment of hierarchy and vectorization. Also Spatial and temporal duplication of animation data was removed through vectorization based on train route. As a result, storage space was reduced, input-output speed and playback speed were considerably improved. According to the test, additional Patternization which followed vectorization brought reduction of over 80% in storage space and input-output speed was quadrupled. Patternization technology can be used as a proper storage method of animation data, and can provide user-specific animation by small data transmission.

In making animation product, it is utmost important to produce comic scene using emphasis and exaggeration. This study aims to research on the comic presentation of animation through application of exaggeration and prominence. First, it suggests going under image extraction experiment and moving-shot-method as a mode of measuring three dimensional shot. Moreover, an analysis of the product of three dimensional shot of animation suggests a comic effect.

컴퓨터 음향발생에 관한 연구는 컴퓨터 음악, 인간-컴퓨터 상호작용, 데이터 청각화등의 분야에서 오랫동안 진행되어 왔지만, 최근 들어 컴퓨터 애니메이션이나 가상세계등에서 시각적 효과와 함께 보다 입체감 있고 현실감 있는 가상환경을 제공하기 위해 더욱더 중요한 문제로 떠오르고 있다. 지금까지 음향발생을 위해 음향의 모델링이나 합성등 음향 자체에 대한 요소 기술들에 관해서는 많은 연구가 진행되었으나 컴퓨터 애니메이션, 가상세계등과 같이 영상내 동작 내지 사건과 음향이 서로 밀접하게 연관된 분야에서 필수적인 음향을 영상내 동작과 통합 처리할 수 있는 기술에 대한 연구는 초보적인 단계에 머무르고 있다. 최근 들어, 음향의 입체감과 임장감을 강화하기 위하여 3차원 음향이라는 개념이 도입되고 있고 이의 구현에 대한 연구가 활발하게 진행되고 있다. 여기서는 컴퓨터 애니메이션이나 가상현실등에서 영상내 물체의 움직임이나 사건 그와 동기된 음향의 자동생성 및 이의 3차원 음향효과 발생 기술 원리를 사이버음향(CyberSound)이라는 개념으로 묶어서 소개하면서, 이의 전망을 기술하고자 한다.

This study investigated the effect of visual learning preference levels in computer assisted instruction (CAI) using static graphics and animations on students' conceptual understandings, application abilities and learning motivations. Fifty-nine seventh graders were selected from a middle school in seoul, and they were taught about the motion of molecule for 4 class hours. Two-way ANCOVA results revealed that the scores of the conception test of the animations group, regardless of student's visual learning preference levels, were significantly higher than those of the static graphics group. However, there were no differences between the two groups in the scores of application test and learning motivation test.

The appearance of digital culture contents swiftly has changed the culture in domestic and international areas in recently and the digital cartoon and animation have become the most important expression media in contemporary age. The digital cartoon and animation industry have attracted the attention of the people as the business of the OSMU(One Source Multi User) which has the possibility to expand and to enhance the added value not only for the field of image and character business but also for the area of the advertising and tourist business. Therefore, in this paper, 1 study on education and development of the digital cartoon and animation. Firstly, I study on definition and type of the digital cartoon, and work flow of the cartoon contents production. Secondly, the purpose of this study is to analyze and research the domestic business trend of the digital cartoon and animation. Finally, 1 propose the plan of policy and education of the digital cartoon and animation.

We propose a novel non-photorealistic rendering technique which generates a cutout animation from a video for UCC. Our method consists of four parts. First, we construct an interactive system to build an articulated character. Second, we extract motions from an input video. Third, we transform motions of a character in order to reflect characteristics of cutout animations. Fourth, we render the extracted or transformed components in cutout animation style. We developed a unified system for a user to easily create a cutout animation from an input video and showed the system generated a cutout animation efficiently.

Animating multiple characters to compete with each other is an important problem in computer games and animation films. However, it remains difficult to simulate strategic competition among characters because of its inherent complex decision process that should be able to cope with often unpredictable behavior of opponents. We adopt a reinforcement learning method in Markov games to action models built from captured motion data. This enables two characters to perform globally optimal counter-strategies with respect to each other. We also extend this method to simulate competition between two teams, each of which can consist of an arbitrary number of characters. We demonstrate the usefulness of our approach through various competitive scenarios, including playing-tag, keeping-distance, and shooting.

3D character animation grow rapidly with the development of computer graphic technology and software. Nowadays 3D character animation holds a important position in the various industry fields including movie, advertisement, animation, and game. With the rapid growth of computer graphic, real time animation of complex characters as well as high quality rendering, which was impossible before, are now prevailing. What is remarkable in this growth is the appearance of virtual idol. The virtual idol plays a leading role in 3D character animation and has a synergy effect in the field of fancy and theme park industry. The aim of this inquiry is to examine the status of computer graphic skill and media related to the 3D character animation to search out the problems in the fields and to propose the solution of the problems

Government set violence as one of the important criteria when it rates movies or TV programs for juveniles. The purpose of selling this criteria is to prohibit the violence in TV programs or movies from affecting the actual behavior of juveniles. However, it is still under discussion how much the violence in broadcasting media actually affects juvenile violence. Korea once carried out a social experiment on juvenile violence media. Back in 1970, violent animation was popular in Korea and Korean government completely banned televising violent animations from September 1980 in an effort to prevent juvenile violence. Investigating the effect of this policy on juvenile violence would draw some implications. The result shows that the policy to ban violent animation in September 1980 didn't have meaningful effect on the trend of juvenile violence. The implication from this paper is that there is no certain cause-and-effect relationship between violent animation and juvenile violence. Another implication is that In-depth discussion is needed if this governmen4 policy is violating the juvenile's right to choose public media.
