Practice education using virtual medical simulation has been recently introduced to maximize the learning efficiency in clinical environment. Specially, in minimally invasive surgery, the necessity of virtual surgery medical simulation has been substantially increased. Since cauterizing effect occurred frequently in minimally invasive surgery has been represented by simple bleeding, realistic cauterizing effect animation has not been proposed yet. In this paper, we propose realistic real-time cauterizing effect animation. Proposed method changes the individual element of each vertex color of the mesh and uses sigmoid function to impose weights for the smooth color change inside the valid mesh region so that the results of cauterizing effect animation was realistic. In addition, by proposing cauterizing color buffer, overlapped cauterizing effects can be realistically represented. Proposed method greatly improves the sense of the real and absorption in virtual surgery medical simulation so that the education efficiency of doctors and students using medical simulation can be maximized.

This paper examines the ink on paper technique that is being used in the animation works by the Canadian filmmaker Michēle Cournoyner from the National Film Board of Canada. It also discusses how in her animated film "Soif"(2013) this technique has been applied to compose the narrative significance and symbols through the use of metamorphosis as a form of artistic expression. Cournoyner had used the ink of paper technique as a means to abandon realistic representations of movement, and in "Soif" through expressive use of metamorphosis, portrayed changes of images in character and object not through chronological order of narrative flow, but through the body of the female character, which had been represented by the improvisation of the ink on paper technique in order to express the surrealistic and unconscious state of mind in animation. Also, the use of Surrealist automatism had been incorporated to evoke the film towards a form of abstract and metaphysical expression, which in terms of expression and technique connects with the character in the animation to give emphasis to its relevancy with the subject matter of the work.

최근 다양한 2D 기반 스케치 기법이 제시되고 이를 활용한 다양한 어플리케이션이 제작되고 있다. 이러한 스케치 기법들은 사용자의 인터페이스에 많은 영향을 주고 있다. 그 중에 제스처 기법은 사용자의 글자 인식과 메뉴의 빠른 접근을 위해서 널리 사용되고 있다. 본 논문에서는 페이퍼 커팅 기법이라고 불리는 예술 분야의 기술을 구현하기 위해서 제스처를 활용한 인터페이스를 제시하고 향후에 이를 응용한 모바일 분야에서의 응용에 대하여 고찰해 보았다. 본 논문에서는 구현을 위하여 제스처 인식 방법을 위한 스케치 인식과 애니메이션을 위한 시간 조정 방법을 제시 하였다.

The purpose of this study is to analyze collage of animated film is able to build up total embodiment of thought. Surrealism Collage intend to combination of various characters including new attempts and pluralistic features. In particular, the fantastic, irrational characteristics of expression and extravagant and unfamiliar artistic technique of Surrealism Collage are actively introduced and explored as elements to make new image and suggest the possibility of another reality. This image has been connected Raoul Servais animation film called . The use of this film technique gives a touch that is sensibly different from the digital encrustation technique which justifies it. Representative animator of Surrealism Raoul Servais expands the domain of his own creative works by succeeding to Surrealistic movement.

The purpose of this research is to study a case of allegory and experimental presentation technique in Film by Zbigniew Rybczynski. It is to analyse this study is to inquire into the fact that experimental animation carries diverse interpretation of comtemporary art and the purpose of this study is to identify certain style through the interpretation of allegory focused on film Tango which has expanded the field of experimental animation with the unique form of the film structure and technique. Therefore, in this research, I would highlight the characteristic of allegory in Film by Zbigniew Rybczynski and research the experimental presentation technique that appears in experimental animation focused on "fragmentation" which are the expressive style of allegory.

The animation film , which became a worldwide sensation with its theme song 'Let it go', did not only rank first in the U.S. box office - it was also the greatest box office hit in the history of Disney animation. Why did , recreated into a musical animation, become a worldwide success and what were the characteristics of its materialized hybrid visual direction technique? In order to look into this, firstly, literature on musicals and animations were studied, and secondly, analysis standards were drawn for musical characteristics of musicals and direction techniques of animations. Thirdly, analyzation and investigation will be conducted on hybrid visual direction techniques based on the research above with as the example. Through this study, it's known that realizes its musical features such as 'exaggerated acting,' 'delivering the meaning of circumstances', 'dramatic expression of emotion' and etc. through animated characters and that its background music is aided by 'narrative features' through its musical composition. Besides, its snow effect through animated VFX composing scenes along with its musical characteristics realizes hybrid image direction. It can be said that image directing effects of musical animations through hybrid grafting and the characteristics of image aesthetics generate public demands worldwide.

As mobile devices have developed, flash animations suitable for the existing web have solved part of the weakness caused by the image quality deterioration and the transmission capacity, but it is difficult to express 3D stereo-scopic images. Also, for the real time-randering of visual expressions for animation and the device technique for smartphone to accord with commercial demands, it is required to develop the 3D image processing technique. This paper studied on the image processing method for 3D animation capable of 3D graphic rendering with view system of android and OpenGL M3G in an embedded system device and OpenGL ES 2.0 library.

Research field on crowd animation can be classified into two major categories. One is to offer realism of the crowd motion and the other is to improve speed of the animation. For the last decade, a lot of research on realism and behavior of crowd have been presented. But lately, research on improving speed seems like more interesting. Therefore, in this paper, we conducted an experiment to analyze what is the main bottleneck of crowd animation. As the result, we find out one of the most important bottleneck is the number of joints transformed in each animation frame. In order to resolve this problem we propose a novel level-of-detail technique 'motion level-of-detail', which is a joint-reduction technique operated in the pre-processing time. We used a non-linear optimization, SQP (sequential quadric programming), to generate the low detailed motions.

one of the most difficult thing for beginner animators is timing. In animations, timing can help to make character animatedly and have function that delivers the character's feeling. However, it is impossible to formulate this timing, since timing for certain time and situation can only express the character's environment, so it is important to make you own timing. the timing has special relationship with animation sounds. This sound decides the animation's mood. Even only accurate cord and music can make dramatic mood for animations. One of the technique is mickey mousing which synchronizes movement and music together. This these will explain about the animation sound using mickey mousing technique to get for animation timing and character movement followed by sound rhythm and tempos with examples 'Tom and Jerry' and 'Nightmare of christmas'.

온라인 게임에서 개인의 분신으로 활용되던 아바타는 2000년 '세이게임"이라는 포탈 사이트를 통해 본격적으로 인터넷 사이트에 등장하였다. 이후 아바타는 게임 및 인터넷 커뮤니티에서의 자신을 대변하는 기능을 넘어, 다양한 형태의 캐릭터 비즈니스로의 가능성이 부각되고 있다. 웹사이트에서 제공되는 아바타 시스템은 GIF 파일 포맷을 기본으로 하여 제공되며, GIF Animation을 이용하는 경우 애니메이션 아바타를 표현할 수 있었다. 그러나 모바일 환경에서는 GIF Animation이 지원되지 않아 애니메이션 아바타를 표현할 수 없었다. 본 논문에서는 SVG Animation 기법을 활용하여 개인용 컴퓨터외에 다양한 모바일 환경에서도 구현이 가능한 애니메이션 아바타 시스템을 설계, 구현하였다.현하였다.
