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.

This study investigated an evolutionary process of In-game Animation and researched on the action of realization establishing virtual reality. In-game Animation, functioning as contents to visualize games, is responsible for conveying information to achieve goals of games. In-game Animation which is affected by graphic technology was initiated with setting up indicators by dot and line. Followed by the development of technology, In-game Animation has pursued realization, after passing through processes of iconography, materialization, and dimensionalization. The realization of In-game Animation does not simply imitate the real world but creates meaning of reality by establishing space with various factors such as characters and background along with the story, under the premise of virtuality. The realization of In-game Animation is very important to provide the experience of immersion, as it forms a sense of presence through such visual tactility. The process to create meaning of reality provides gamers with experiences, and leads them to expand senses through visual perception and finally absorb the virtuality as reality. Therefore, the image of In-game Animation does not simply imitate the real world but creates meaning of reality by establishing space with various factors such as characters and background along with the story, under the premise of virtuality. The realization of In-game Animation is not limited to blindly portray a realistic image. In addition, the process of realization pursued by In-game Animation is an action to immerse in the game rather than a mere product of technological development.

Recently, practice education using virtual medical simulation has been applied to real clinical environment by enhancing the learning efficiency. Specially, in minimally invasive surgery, the necessity of virtual surgery medical simulation has been increased. Realistic bleeding animation, which represents bleeding special effects frequently occurred in virtual medical simulation environment, has not been proposed yet. In this paper, we propose realistic real-time bleeding animation. For bleeding simulation, proposed method calculates main and effective bleeding regions along the main bleeding direction vector to represent naturalistic bleeding effect. In addition, for bleeding rendering, proposed method uses sigmoid function to impose weights of vertex opacities for the smooth opacity change so that the results of bleeding animation is realistic. Proposed method 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 enhanced.

H-Anim is an international standard that Humanoid Animation Working Group in Web3D Consortium defined the data structure necessary for human animation. Various libraries and tools have been generated according to the structure, but they still have restrictions to represent realistic humanoid motions. This paper presents the method of generating realistic human motion using motion capture data in order to define motion for humanoid animation based on H-Anim standard. In order to implement this, we have defined a data structure capable of receiving motion capture data and implemented a motion browser. The human motion data structure defined in this paper is based on X3D and intended to have compatibility through networks and various browsers.

Art has evolved into remarkable changes in its art form maintaining a close link with the contemporary scientific technologies that gave birth to new tools of expression in each era. Animation is an art form in an inextricable connection with technological aspects because it was spawned by the technical background like movies. In this regard, animation is often viewed very strongly by technical advancements in terms of an aesthetic approach. John Whitney Sr., one of the pioneers in computer graphics arts, turned his attention to the new technology called computer graphics as a means to visualize images and movement. The advent of a new medium had a strong influence not only on tools and means for novel expression but also on the gradual shift in thinking about arts and even the audiences' taste. In the 1980s, animation was combined with computer technology and the rapid progress of computer graphic technology opened up the era of new visual aesthetics, Today, the development of digital technology presents a different dimension of realism, either advocating hyperrealism by digital actors or presenting new illusionism by classic cartoon characters emphasized in a distortion or metamorphosis from a real life in order to consolidate animation realism. Based on the two perspectives mentioned above, this study can identify methods of digital character appropriation focused on the works of the ACM SIGGRAPH Asia and find how the relationship between art and technology has changed the digital realism and evolved the digital character as the digital technology has developed.

From 1949 to 1966, after the new China was established, in order to consolidate newborn regime and erect national image, "proletariat revolutionary education" had become the main way of literary and artistic creation in the new era. In this era, Chinese animation began to produce to form the characteristics of emphasizing the ideological expression and political education from 1949 to1966, but it also made people misunderstand that it was the results of comprehensive containment of Soviet literary thoughts and creative models. In fact, Regardless of the subject matter, narrative, and role, Chinese animations have inherited and developed the ideological characteristics of the "Mun-yi-jae-do" literary view, forming a creative style that is different from the Soviet "dogmatism." The characteristics of "revolutionary hero role", "mythological expression of revolutionary thought" and "unique storytelling narrative mode" in Chinese animation from 1949 to 1966 were the inheritance and development of the "hero role", "mythological story", and "art of storytelling" of the important expression means of traditional art creation after the establishment of the "Mun-yi-jae-do".

The development of computer graphics leads to high value-added products, such as film, game contents, 3D animation. In realistic animation, it is impossible and inefficient to produce the movement of each objects as handwork to display the various behaviors of a lot of characters. So we need the techniques of the crowd animation which presents the movement of objects realistically and efficiently by calculating automatically. In this paper, we designed a modeler which generates the attitudes of objects in crowd behavior animation using information of 3D models. We developed an animation system for crowd behavior which was applied for animation, VR, or games.

Human fingers are essential parts of the body that perform complex and detailed motion. Expression of natural finger motion is one of the most important issues in character animation research. Especially, keyboard typing animation is hard to create through the existing animation pipeline because the keyboard typing typically requires a high level of dexterous motion that involves the movement of various joints in a natural way. In this paper, we suggest a method for the generation of realistic keyboard typing motion based on physics simulation. To generate typing motion properly using physics-based simulation, the hand and the keyboard models should be positioned in an allowed range of simulation space, and the typing has to occur at a precise key location according to the input signal. Based on the observation, we incorporate natural tendency that accompanies actual keyboard typing. For example, we found out that the positions of the hands and fingers always assume the default pose, and the idle fingers tend to minimize their motion. We handle these various constraints in one solver to achieve the results of real-time natural keyboard typing simulation. These results can be employed in various animation and virtual reality applications.
