Drawn-on-film animation technique is one that neither is actively used nor receives attention in any video content area. This paper means to strengthen animation genre's future direction and aesthetic aspect by seeking to newly discover previous experimental techniques through this paper. Taking into account the details of paper, it was intended to systematize and introduce results and experiential information obtained by researcher from applying drawn-on-film animation techniques in actual educational arena and utilizing these in learning and newly created techniques and the like through this. Production processes were comparatively demonstrated after suggesting an alternative digital production system in this process. And ultimately, a study and proposal was made so as to be helpful in developing the techniques of animation genre.

Animation is completed in accordance with the original planning of visual direction in the process of post-production. Especially, a variety of visualization skills to meet the planning idea are directed in editing and compositing processes such as rendering and shading in the production of 3D animation. Therefore, the studies how to implement these visual effects have been conducted since the emergence of the animation. The rendering method which appears in the recent animations so often is the effect of 2D animation style although it is applied by 3D technique. 3D animation can be classified as two types including photo realistic and non-photo realistic renderings. The former is to render the images realistically while the latter is to highlight the formative effect with analogue style free from the realism of the photographs. Visual effect of 2D animation is non-realistic, that is, non-photo realistic rendering. The animations produced by this method have the depth of 3D animation expression in terms of space and animating, and can direct the viewer-friendly analogue style visuals, which are widely used as a post-production effect. Hence in this study, we selected a short animation, 'Paperman,' one of Disney's animations, produced by cartoon rendering method which belongs to the class of non-photo rendering technique in 3D graphics, as our subject. We analyzed their techniques and visual effects of the scenes expressed by cartoon rendering method so as to understand whether they meet the original direction idea with the composition work. In addition, we expect further developments of post-production methods, exceeding the limit of graphic expression in alignment with the trend that has become more various in the types and genres of non-photo rendering.

대중에게 하나의 취미 생활로 자리매김한 게임은 특징이나 작동 방법에 따라 다양한 장르로 발전되었다. 그 중 액션게임 장르는 사용자가 조작하는 캐릭터의 역동적인 움직임과 움직임이 큰 동작으로 인해 사용자로 하여금 게임 플레이에 몰입할 수 있는 특징을 가지고 있다. 과거 2D 환경의 게임에서 연속되는 그림으로 표현되던 캐릭터의 애니메이션 장면은 3D 환경으로 발전하면서 새로운 애니메이션 기법을 필요로 하였으며, 현재 다양한 애니메이션 기법이 연구되고 있다. 본 논문에서는 3D 뼈대 애니메이션 통하여 DirectX에서의 캐릭터 애니메이션 적용 대해 설명한다.

본 연구에서는 3D 애니메이션 기법을 이용하여 기계 내부의 동작을 표현하였고, 도입된 기법의 장단점을 비교 검토하였다. 본 연구에서 표현한 애니메이션의 기획은 다양한 기계의 동작의 핵심원리에 목표를 두었다. 또한 본 연구에서는 실제에 가까운 애니메이션을 제작하기 위하여 기계 동작애니메이션을 Key 애니메이션 방법과, 링크를 사용한 IK 방법뿐만 아니라 Bone 애니메이션 방법에 대하여 장단점을 파악하고, 각각의 기계 내부 동작 표현에 대한 방법을 분류하였다. 본 연구가 콘텐츠화 된 시뮬레이션을 만드는데 하나의 프로세스로서 상당부분 기여할 수 있음을 확인하였다.

Modern society has produced various forms of mass media to convey different messages to the public.Animation, in particular, has been developing and expanding its own unique ganre and cultural code. In this report, I first describe the basic definition and expression techniques of filmography. Based on these technique, I observe the characteristics and methodologies of animation aesthetics, and distinguish between animation and motion pictures in order to show the benefits of using animation. Finally, I suggest the future direction of the research we will pursue in order to efficiently carry message to the public.

Now a day, lots of the animations include TV series Animations are made by the technique of 3D Animation. However, 3D Animation obstructs visual elements and deteriorates an acquaintance with the limit of unfamiliar material methods and dispersion of light. For this reason, a large of number of 3D Animations are repacked with the style of 2D Animation. Most of previous studies for the conversion of output 3D Animation to the style of 2D Animation are analysis for 2D rendering techniques. In case of Non-realistic 3D Character Animation, first and foremost it needs investigation of the basic producing method for the 2D Animation is different with the realistic expression way of the one for the 3D animation. For a case study, expression methods for the non-realistic and the non-actuality 2D Character Animation come with impossible ways in the real life. This study for the 3D Animation with the style of 2D Animation is to investigate on the keynote for effective expression methods, when we turn 3D Animation into the style of 2D Animation.

Since the first episode of (1995) by Pixar, a world leading animation company, 3D animation has been focused on realistic motion and rendering techniques. However, in 2018, 3D animation was released, with unique backgrounds created through illustration techniques and dynamic movements of characters that seemed to be produced by hand rather than computers. It shows a lot of difference from other 3D animations. In this study, I analyzed 's new production techniques and expressions into two categories, first, the use of old comics techniques, and second, other factors that made the animation stand out. in 3D animation market focused on realistic motion and rendering techniques can have positive implications in terms of expanding animation diversity. This study is expected to be used as academic or research data for researchers studying new production techniques in related fields.

Implicit Integration has become a standard approach to efficient cloth animation, and it guarantees the stability of the system so that large steps can be used. Therefore, it is regarded as the best method for the real-time or interactive animation of cloth. Since the implicit method was introduced for stable cloth animation, various cloth animation techniques based on the method have been proposed. It is now possible to generate the real-time animation of cloth model with thousands of mass-point in general PC environments. Although the implicit method guarantees the stability, the implementation of the implicit method is generally more difficult than that of the explicit method. Even worse, it is very difficult to parallelize the computation process of the implicit method. The cloth animation with implicit method can be formalized as a linear system solving. In this paper we propose an stable and efficient cloth animation techniques based on the implicit method. The proposed method can be easily parallelized. Self-collision is another important issue in cloth animation, we also propose an efficient self-collision avoidance techniques.
