At present, it is very common to use techniques beyond the 2D (two-dimensional) in animations which are found in motion pictures, OVA and TV series. As you can see, PIXAR and Disney have reduced their 2D departments and recently put more effort into 3D (three-dimensional) animation. There is no doubt that producing 3D animation is the big trend. Along with this trend, the national education institutions and the national support policies are also changing to be supportive of 3D animations. We, however, should ask ourselves, if we are on the right track with this change. Through the analysis of the methods of creating 2D animation which we should keep as it is, but instead we import and incorporate with 3D techniques of Japanese 2D animation, I would like to present the importance and the significance of the 2D animation and also to suggest an effective way to create 2D fused with 3D computer graphics techniques.

Animations are filled with emotional expressions of childlike innocence and fun, their dramatic plots and boundless imaginations have made them the focal points in a global context featuring industrialization and marketization, and people around the world like watching these animations. Animated adaptations are very common artistic phenomenons and cultural practices, and they have been one of central topics of theoretical discussions since the creation of animation films. Currently, the research on animated adaptations is mainly about case analysis, but from the perspective of methodology, there lacks a theoretical and systematic study on the adaptation and recreation of narrative text. This paper takes western narratology as the theoretical tool to do a systematic research analysis on the narrative adaptation of animation films, and it will involve the method and values of animated adaptation. This paper used to the method of 'Greimas' and to study the procedure of adaption from an origin to an animation. The paper found the success factors in animation through it.

The most important goal of character animation is to efficiently control the motions of a character. Until now, many techniques have been proposed for human gait animation, and some techniques have been created to control the emotions in gaits such as "tired walking" and "brisk walking" by using parameter interpolation or motion data mapping. This paper proposes a human running model based on a one-legged hopper with a self-balancing mechanism. The proposed technique exploits genetic programming to optimize movement, and can be easily adopted to various character models. We extend the energy minimization technique to generate various motions in accordance with emotional specification.

This paper presents a concurrent watermarking scheme with both robustness and fragileness for copyright protection and authentication of 3D animation contents. In a 3D animation model, the proposed scheme embeds not only robustly the watermark into geometry node for copyright protection but also fragilely the watermark into position and orientation interpolators for content authentication. This paper names the former as the robust geometry watermarking and the latter as the fragile interpolator watermarking. The proposed scheme performs independently these watermarkings for satisfying at one time the robustness and the fragileness of 3D animation model. From experimental results, we verified that the watermark embedded by the geometry watermarking has the robustness against many attacks from 3D public editing tools and also the watermark embedded by the interpolator watermarking has the fragileness against the same attacks.

The role of sound in producing 3D animation clip is one of the important factor to maximize the immersive effects of the scene. Especially interaction between video and sound makes the scene expressions more apparent, which is diversely applied in video production. One of these interaction techniques, the out-focussing technique is frequently used in both real video and 3D animation field. But in 3D animation, out-focussing is not easily implemented as in music videos or explosion scenes in real video shots. This paper analyzes the sound data to synchronize the depth of field with it. The novel out-focussing technique is proposed, where the object's field of depth is controlled by beat rhythm in the sound data.

In these days, the term 'snack culture' has been popularized as on of the tendency of new content consumption, and various related contents are introduced. This study is an analytical study related to the snack animation content based on the webtoon which can be considered as a representative snack culture content. The Purpose of this study is to investigate the frequency of use of transition techniques, which are importance for viewer to help to understand story by making space and time change in the moving image. To do this, I analyzed the each type of transition technique about the whole contents of NAVER's play webtoon, which is representative snack animation platform. Then I derived and contemplated the result of the analysis with a viewpoint of composition of shot. Through this process, I think this study could provide another basic data about snack animation contents which are not been studied enough yet.

본 논문에서는 음성에 따른 얼굴 애니메이션을 사실적으로 표현하기 위한 조음기관(혀, 성대 등)의 움직임을 시각화하는 방법을 제시한다. 이를 위해서, 음성에 따른 얼굴 애니메이션을 위한 말뭉치(Corpus)를 생성하고, 생성된 말뭉치에 대해서 음소 단위의 분석(Phoneme alignment) 처리를 한 후, 각 음소에 따른 조음기관의 움직임을 생성한다. 본 논문에서는 조음기관의 움직임 생성을 위해서 얼굴 애니메이션 처리에서 널리 사용되고 있는 기저 모델 기반 형태 혼합 보간 기법(Blend shape Interpolation)을 사용하였다. 그리고 이를 통하여 프레임/키프레임 기반 움직임 생성 사용자 인터페이스를 구축하였다. 구축된 인터페이스를 통해 언어치료사가 직접 각 음소 별 조음기관의 정확한 모션 데이터를 생성토록 한다. 획득된 모션 데이터를 기반으로 각 음소 별 조음기관의 3차원 기본 기저를 모델링하고, 새롭게 입력된 음소 시퀀스(phoneme sequence)에 대해서 동기화된 3차원 조음기관의 움직임을 생성한다. 이를 통해 자연스러운 3차원 얼굴 애니메이션에 적용하여 얼굴과 동기화된 조음 기관의 움직임을 만들어 낼 수 있다.

온라인 게임 내의 가상재화인 게임 머니 취득을 목적으로 한 게임 봇의 사용이 게임 서비스에 심각한 문제를 야기하고 있다. 때문에 게임 회사에서도 보안 솔루션을 도입하는 등 여러 가지 대응을 시도하고 있으며 그에 대한 사례로 실제 라이브 서비스에서 게임 봇 탐지에 사용하였던 애니메이션 유사도 분석 프레임워크를 제안한다. 사람과 게임 봇 간에는 애니메이션 패턴 차이가 존재하기에 이를 분석하면 게임 봇을 탐지할 수 있다. 제안하는 프레임워크는 도메인 전문가가 설정한 룰셋에 의존하지 않고 애니메이션 패턴 데이터를 기반으로 생성한 모델을 활용하기에 작업장에서 우회하기가 어려우며, 분석 모델 업데이트만으로 대응이 가능하다는 점에서 게임 운영상 장점이 많다. 이러한 장점들로 향후 애니메이션 패턴 유사도 분석 기법이 게임 봇 탐지에 다양하게 활용될 수 있을 것으로 기대된다.

애니메이션은 이미지나 텍스트와 같이 정적인 방식에 비해 효과적인 정보전달방식이다. 이는 간단한 표현이라도 동적인 움직임으로 구성될 때 더욱 흥미를 유발하며 높은 전달력을 가지게 되기 때문이다. 그러나 현재 웹 환경에서의 애니메이션 제작 방식은 전문적인 제작 도구를 사용하는데 국한되어 있어, 일반적인 사용자들의 참여를 통한 활용에는 적합하지 못한 방식이다. 본 논문은 사용자의 의도를 쉽고 직관적으로 반영할 수 있는 애니메이션 생성 인터페이스 기법을 제안하며, 실제 웹 환경에서 정보의 공유와 의사전달에 있어 직관적이고 쉬운 방식으로 애니메이션을 활용하는 방안을 제시한다.

This paper will be devoted to investigation of recent changes in cultural policy. This includes the increasing policy concern with 'social effects' of culture and the development of policies for 'cultural and creative industries'. British creative industries approaches the arts as a business that can both sustain individual artists and lead to wealth creation in the economy of whole countries. In this context, this study aims to investigate the comparison and contrast of the impact and stature of the UK creative industries with those from South Korea.
