Recently, the use of Unreal Engine for animation production is increasing. In this situation, Unreal Engine's 'MetaHuman Creator' helps make it easier to apply realistic characters to animation. In this regard, we tried to produce animations using 'MetaHuman' and verify the effectiveness and differences from the animation production process using only Maya software. To increase the efficiency of the production process, the animation process was made with Maya software. We tried to import animation data from Unreal Engine and go through the process of making animations, and try to find out if there are any problems. And we tried to compare animations made with realistic 'MetaHuman' characters and animation works using cartoon-type characters. The use of the same camera lens in realistic character animations and cartoon character animations produced based on the same scenario was judged to be the cause of the lack of realistic animation screen composition. The analysis revealed that a different approach from the existing animation camera lens selection is required for the selection of the camera lens in the production of realistic animation.

이벤트의 캐릭터는 특유의 소프트한 측면과 생명력으로 행사의 차별화 및 일반대중과의 친숙도 제고는 물론 무한한 상업적 부가가치로 그 중요성이 더욱 부각되고 있다. 특히 위성방송의 활성화로 전세계 단일 네트워크 권에 있는 오늘날에 있어서 그 역할을 무한하다고 하겠다. 따라서 단순한 행사의 상징으로 사용되었던 시기에 명명된 마스코드(Mascot)라는 용어보다 이벤트 아이덴티티 캐릭터(Event Identity Character)라는 용어가 더 적합하다고 할 수 있지만 행사의 조직위원회와 국제아시안게임조직위원회에서 공식적으로 사용하는 용어가 마스코트이므로 그대로 사용하도록 하겠다. 국내 지방자치도시로는 처음으로 국제적 하계 스포츠행사를 유치한 부산아시안게임의 마스코트를 개발하고 그 활용방안을 제안함으로써 행사의 객단가를 높임은 물론 행사에 대한 내, 외국 관객의 기대심리를 충족시키고자 하였다.

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.

본 논문에서는 인권이 조명되는 요즘 문화콘텐츠에서 여성이나 성소수자 캐릭터가 조금씩 등장하기 시작했지만, 여전히 보기 힘든 장애인 캐릭터, 그중 게임콘텐츠에 집중해 알아보고자 한다. 게임에서는 주로 장애가 없는 성인 남성이 주인공으로 등장하나, 장애인 캐릭터가 아예 등장하지 않은 것은 아니다. 지금까지 게임에 나타난 장애인 캐릭터는 어떤 종류의 장애를 가지고, 장르에 따라 어떻게 표현되는지 연구하였다.

We present a novel approach to producing facial caricature with Simpson cartoon style based on Moving Least Squares (MLS). We take advantage of employing the caricature stylization rule of caricature artist, Justin. Our method allows Simpson-style cartoon character similar to user's features by using Justin's technique, which is a set of caricature stylization rules. Our method transforms input photo image into Simpson style caricature by using MLS approximation. The unique characteristics of user in the photo can be detected by comparing to the mean face feature and the input face feature extracted by AAM(Active Appearance Model). To exaggerate the detected unique characteristics, we set up the exaggeration rules using Justin's technique. In addition, during the cartooning process, user's hairs and accessories are used to the deformed image to make a close resemblance. Our method preserves the reliable and stylized caricature through the exaggeration rules of the actual caricature artist's techniques. From this study, we can easily create a Simpson-style cartoon caricature to resemble user's features by combining a caricature with existing cartoon researches.

최근, 3차원 그래픽스 기술은 애니메이션 필름 제작에 있어서 자주 사용된다. 그러나 많은 애니메이션 필름들은 3차원 그래픽스 기술을 사용하여 제작되더라도, 2차원 셀 애니메이션 효과를 내려고 한다. 3차원 그래픽스 기술을 이용하여 2차원 셀 애니메이션의 효과를 내기 위해서는 렌더링에는 카툰 렌더링이 사용 된다. 그러나 이를 제외하고도 몇 가기 기술이 더 필요한데, 그중 하나가 만화 캐릭터(character)의 만화스러운 움직임이다. 기존의 연구 중에는 기존의 모션을 만화적 모션으로 변형하려는 시도가 있었으나, 셀 애니메이션의 캐릭터 움직임과 차이가 있었다. 또 생성된 모션이 만화적 모션인가 하는 의문에 대한 평가 기준이 없기 때문에, 만화적 모션의 모호성 문제가 발생하였다. 본 논문에서는 직접 애니메이션에서 모션을 얻어내는 시스템을 제안한다. 2차원 애니메이션 동영상에서 2차원 캐릭터의 자세를 보고 3차원 캐릭터의 자세로 반자동 맵핑하여, 3차원 캐릭터의 애니메이션 키 프레임을 생성하고, 이 키 프레임간의 보간을 통해 3차원 캐릭터 애니메이션을 생성한다. 생성된 3차원 캐릭터 애니메이션은 만화적 움직임을 갖게 되며, 2차원 캐릭터의 자세와 움직임을 기준으로 만들었기 때문에, 만화적 모호성을 극복할 수 있다.

As interest in the metaverse has grown, there has been a demand for avatars that can represent individual users. Consequently, research has been conducted to reduce the time and cost required for the current 3D human modeling process. However, the recent automatic generation of 3D humans has been focused on creating avatars with a realistic human form. Furthermore, the existing methods have limitations in generating avatars with imbalanced or unrealistic body shapes, and their utilization is limited due to the absence of datasets. Therefore, this paper proposes a new framework for automatically transforming and creating stylized 3D avatars. Our research presents a definitional approach and methodology for creating non-realistic character avatars, in contrast to previous studies that focused on creating realistic humans. We define a new shape representation parameter and use a deep learning-based method to extract character body information and perform automatic template mesh transformation, thereby obtaining non-realistic or unbalanced human meshes. We present the resulting outputs visually, conducting user evaluations to demonstrate the effectiveness of our proposed method. Our approach provides an automatic mesh transformation method tailored to the growing demand for avatars of various body types and extends the existing method to the 3D cartoon stylized avatar domain.

With the spread of Internet, web users express their daily life by articles, pictures and cartons to recollect personal memory or to share their experience. For the easier recollection and sharing process, this paper proposes diverse cartoon generation methods using the landmark lists which represent the behavior and emotional status of the user. From the priority and causality of each landmark, critical landmark is selected for composing the cartoon scenario, which is revised by story ontology. Using similarity between cartoon images and each landmark in the revised scenario, suitable cartoon cut for each landmark is composed. To make cartoon story more diverse, weather, nightscape, supporting character, exaggeration and animation effects are additionally applied. Through example scenarios and usability tests, the diversity of the generated cartoon is verified.

Character industry is not only knowledge-based industry chiefly with copyrights but also motive power for creative economy to take a role functionally over the fields of industries because it has industrial characteristic as complement product to promote sale value in manufacturing industry and service industry and increase profit on sales. Since 2003, the national policy related to character has aimed to maximize effect among connected industries, extend its business abroad, enforce copyrights through the improvement of marketing system, develop industrial infrastructure through raising quality of character products. With the result of this policy, the successful cases of connected contents have been crystallized and domestic character industry has stepped up methodically since 2007. It is needed to reset the scales of character industry and industrial stats because there are more know-how of self industry promotion and more related characters through strategy of market departmentalization starting with cartoon, animation, games, novels, movies and musicals. Especially, The Korea government set our target for 'Global Top Five Character Power' since 2009 and has started to carry out to find global star characters, support to establish network among connected industries, diversify promotion channels, and develop licensing business. Particularly, since 2013, There have been prospered the indoor character theme park with time management just like character experimental marketing or Kids cafes using characters, the demand market of digital character focusing on SNS emoticon, and the performance market for character musical consistently. Moreover, The domestic and foreign illegal black markets on off-line have been enlarged, so we need another policy alternative. To prepare for the era of exploding character demand market and diversifying platform, it is needed to set up a solid strategy that is required the elements of policy changes in character industry to vitalize character industry and support new character design and connected contents. the following shows that the elements of policy changes related to the existing policy, the current position of market. Nowadays, the elements of policy changes in domestic character industry are that variety of consumers in the digital character market according to platform diversification, Convergence contents of character goods for the Korean waves, legalization of the illegal black contents market, and controling the tendency of consumers in departmentalized market. This can help find the policy issue entirely deferent with the existing character powers like US, Japan or Europe. In its final analysis, the alternatives are the promotion of models with contract copyrights of domestic and foreign connected contents, the diversification of profit models of platform economy, the additive development of target market related to enlarging the Korean waves, and the strategy of character market for the age-specific tendency according to developing character demand market.
