In spite of lots of differences in the production process of film animation, the animating method through computer is not much different between game animation and film animation. It is because the principles of film animation are also emphasized for the production of game animation. This study aims to consider the line of action showing the direction of movement and flow of energy among many considerations for the character pose work in case when producing game animation. Starting from the basic theory of drawing, the line of action plays a role of bible in the pose work including cell animation and 3D animation. After examining the theoretical background through preceding researches in order to understand the application of the line of action to the pose work of game characters, the poses of hero characters of a 3D online game 'Over Watch' were collected and then lines were directly drawn to analyze them. And as a result, the pose of characters with simple and clear 'Line of action' was good. This study aimed to consider the expression techniques of character pose in the production of game animation, which is expected to be used as an important reference for game animators at work.

Morphing is a geometric interpolation technique that is often used by the animation industry to transform one form into another seemingly seamlessly. It does this by producing a large number of 'intermediate' forms between the two 'extreme' or 'parent' forms. It has already been shown that morphing technique can be a powerful tool for form design and as such can be a useful addition to the armoury of product designers. Morphing procedure itself is simple and consists of straightforward linear interpolation. However, establishing the correspondence between vertices of the parent models is one of the most difficult and important tasks during a morphing process. This paper discusses the mesh-merging method employed for this process as against the already established mesh-regularising method. It has been found that the merging method minimises the need for manual manipulation, allowing automation to a large extent.

Generally, the animation and image production process consists of three stages: Pre-Production, Main-Production, and Post-Production. Real-time video production is also made based on this configuration. On the premise of the increase of productivity by reducing the production time effectively in the main production stage that takes the most time, this study aims to summarize the process of producing videos, focusing on the concrete main production stage. To do this, we propose a method for creating a real-time image from the point of view of the general user using Unity 3D, one of the game engines. Also, this study utilizes the Cinemachine feature provided by Unity 3D, which is suitable for the implementation of the proposed module structure.

We can anticipate that animations will form one of the axes and lead popular culture in our future visual age. Recently, research has been actively conducted, but it mainly focuses on their value in culture industry or technologies and methods of producing animations. Of course, research that deals with animation characters has constantly come out. This study focuses on the 'formative elements' of 3D animation characters and attempts differentiation from other research by inducing new logic theoretically. Being freed from the research on characters that has been merely focused on theoretical grounds, this study intends to figure out how audience that is consumers who actually get to watch and feel animations recognizes them and find out related problems and also solutions for them. In particular, this study intends to examine the formative characteristics of 3D animation characters with the characters appearing in , one of the animations that have achieved artistic value as well as commercial success. And for that, the study conducted not only literature review but various surveys and Delphi method as well. Also, the researcher devised an analysis frame to evaluate the formative elements through in-depth discussion with experts. And with this, the study created the forms such as the Elements of Form, Formation Methods of Form and Visual Recognition Elements of Form, examined how audience recognized 3D characters. The process of recognizing an image is influenced by socio-cultural environment or sex, age, and the level of knowledge differently. This was meant to investigate current visual culture and the public's perspective through characters in that represent the visual mode.

The appearance of digital culture swiftly has changed the culture in domestic and international arenas before and after the year 2004 and the image and animation have become two of the most important expression media in contemporary age. Among the Japanese animations that have demonstrated the rapid development of cartoon and animation in the world, the director Dakahata Isao's 'Graves of the Fireflies' that has influenced many works has been evaluated as one of the noticeable works that has a unique method and scenario dramatization in terms of producing the original novel into an animation. This study investigates the metaphor and symbolism shown in this work according to each sequence, divides the production ability in the work into three elements and applies them to the important elements such as camera, colors and mise-en-scene when the original work is depicted into image. It can be summarized in more detail as in the following: firstly, I study the rhythm of camera corresponding to the symbolism of the angle that the camera has and production; secondly, I analyze the artistic elements appeared in the process of expressing the original work into the image, especially the production for the colors and symbolism contained in them and the composition of screen. Thirdly, I analyze how effectively the atmosphere for the situations for the original work is expressed in animation with the aid of one of the image elements, mis-en-scene. It is expected that the analyzed findings will be effective as a way of overcoming the limitation of expressions that the original work in text and the study on these processes will become good examples to the relevant workers and will be the good references to the producers who are interested in the creation of animation in Korea.

With the increasing popularity of computer-generated virtual influencers, the trend is rising especially on social media. Famous virtual influencer characters Lil Miquela and Imma were all created by CGI graphics workflows. The process is typically a linear affair. Iteration is challenging and costly. Development efforts are frequently siloed off from one another. Moreover, it does not provide a real-time interactive experience. In the previous study, a real-time graphic workflow was proposed for the Digital Actor Hologram project while the output graphic quality is less than the results obtained from the CGI graphic workflow. Therefore, a real-time engine graphic workflow for Virtual Influencers is proposed in this paper to facilitate the creation of real-time interactive functions and realistic graphic quality. The real-time graphic workflow is obtained from four processes: Facial Modeling, Facial Texture, Material Shader, and Look-Development. The analysis of performance with real-time graphical workflow for Digital Actor Hologram demonstrates the usefulness of this research result. Our research will be efficient in producing virtual influencers.

Recently augmented reality contents are variously used in public such as advertisements or exhibits as well as children's books. Therefore, it is certain that the market, development of augmented reality contents, is gradually growing. Those who are the producer of augmented reality may be familiar with the skill where those images are used as a marker which is created by image recognition technique. In case of using image recognition technique, they usually use the augmented reality marker platform from Qualcomm since it is able to recognize self-produced images and 3-dimensional figures at no cost. This study was started when undergraduate students began to use those general techniques in their contents producing process. AR majoring students in Namseoul University applied image recognition technique to 3 AR contents exhibited in Sejong Center. Creating 3 different images, they have registered images at Image Target Manager provided by Vuforia to use as a marker. Moreover, they have modified the image producing method to raise the recognition rate by research. The higher recognition rate brings the more stable use of augmented reality contents. To achieve the satisfied rate, they have compared the elements of color contrast, pattern and etc. in the use of platform. Thus, the effective image creation method has been drawn. This study is aiming to suggest the production of stable contents by recognizing smart devices' limitation and producing educational contents. The purpose of this study is to help practically augmented reality contents developers by illustrating the application of augmented reality contents which are based on image recognition technique and also its effectiveness at the same time.

Though the education of culture and art for disabled children is very important, it has not been brisk yet until recently due to 'absence of the teaching methods suitable for disability types, levels and programs.'. In this situation, cartoon contents can be used as the most appropriate tools for culture and art education for mentally retarded children. Entertainment functions and genre features of cartoon contents can motivate the applicable children to participate more voluntarily and positively and function as teaching tools for interesting activities. Of course, since it is not proper to apply the cartoon contents for normal children to Special Education Field as they are, cartoon works should be made by understanding closely the characteristics and degrees of retardation of the applicable children and applying them to the composition of cartoons. However, for the contribution of this attempt to education field, it is thought that concrete guidelines for producing cartoon contents considering the concept of various types of disability, emotion, social behavioral traits, ability of cognition, school achievements, and the characteristics of language and physical health should be necessary, and to improve the application of the developed cartoon contents so that they will not remain as superficial results, sufficient communication with the applicable children such as application to classes in the process of development is necessary.

It is important to reuse existing motion capture data for reduction of the animation producing cost as well as efficiency of producing process. Because its motion curve has no control point, however, it is difficult to modify the captured data interactively. The motion transition is a useful method to reuse the existing motion data. It generates a seamless intermediate motion with two short motion sequences. In this paper, Uniform Posture Map (UPM) algorithm is proposed to perform the motion transition. Since the UPM is organized through quantization of various postures with an unsupervised learning algorithm, it places the output neurons with similar posture in adjacent position. Using this property, an intermediate posture of two active postures is generated; the generating posture is used as a key-frame to make an interpolating motion. The UPM algorithm needs much less computational cost, in comparison with other motion transition algorithms. It provides a control parameter; an animator could control the motion simply by adjusting the parameter. These merits of the UPM make an animator to produce the animation interactively. The UPM algorithm prevents from generating an unreal posture in learning phase. It not only makes more realistic motion curves, but also contributes to making more natural motions. The motion transition algorithm proposed in this paper could be applied to the various fields such as real time 3D games, virtual reality applications, web 3D applications, and etc.

The paper starts off with a notion that the most realistic problem in restoring cultural contents' archetype and developing contents industry based on it is the lack of understanding and production about key visual. Thus, with the premise that, in visualizing ancient fantasy as an original archetype subject material, one has to take into account design process for an actual content production, the paper aims for the suggestion of the necessity of key visual through visualization. For this, the paper made an artwork of archetype image based on literature and historical data with which to visualize fantasy elements of Goguryeo's ancient myth and tales that have high utilization value as various subject matters, such as animation and games.
