The feature of digital media's interactivity made the traditional storytelling to be evolved into a new concept of digital storytelling. Unlike films or animations, games' storytelling takes open-ended design method; thus, it is possible to create unlimited number of stones within a game depending upon the decisions of player characters. In this paper, a character-centered game storytelling system of a highly story-based RPG genre will be reviewed, and, it analyzes case studies of how a character with various story values can interact with its background story, virtual game world, and many events in its game storytelling system. Game storytelling structure and game mechanics are related to each other very closely. Therefore, it is possible to control the player's overall movement as the character's story develops according to a predictable structure or situation.

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.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, ′the process of the length of curve being equal to the sum of the vectors when intervals get smaller′ and ′the process of calculating volume of spinning curve by using definite integral.′ Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Also it can help students with solving mathematical problems intuitively. Consequently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the application of definite integral", which exists in mathematical curriculum the second and third grade of high school. When this study is used for students as assisting materials, it is expected the following educational effect. 1. Students will have precise concepts because they can understand what they learn intuitively. 2. Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 3. It is possible to change the teacher-centered instruction into the student-centered instruction. 4. Students will understand the relation between velocity and distance correctly because they can see the process of getting the length of curve by vector through the monitor. For the purpose of increasing the efficiencies and qualities of mathematics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, teachers have to use the CIA program carefully.

Most animation films running on cinema or TV are based on 3D images. Domestically, a lot of 3D animations are produced, and the number of 3D animation films are on the annual rise. Many human resources relating to animation participate in a variety of domestic and foreign animation projects of domestic producers. In the animation participate in a variety resources are of more importance. As a result, many university make the effort to raise human resources for 3D animation. In this paper, we will look into the curriculum of 3D animation. In particular, based on the questionnaire survey in which domestic 3D animation producers participated, this study analyzed the survey results and tried to discuss how to rise human resources for creative 3D animation in university. It is aimed at suggesting the directions of raising human resources for 3D animation in proper 3D animation education and of their contributions to the development of the domestic 3D animation industry.

In this paper, we describe the development of a system for generating a 3-dimensional human face using 3D scanned facial data and photo images, and morphing animation. The system comprises a facial feature input tool, a 3-dimensional texture mapping interface, and a 3-dimensional facial morphing interface. The facial feature input tool supports texture mapping and morphing animation - facial morphing areas between two facial models are defined by inputting facial feature points interactively. The texture mapping is done first by means of three photo images - a front and two side images - of a face model. The morphing interface allows for the generation of a morphing animation between corresponding areas of two facial models after texture mapping. This system allows users to interactively generate morphing animations between two facial models, without programming, using 3D scanned facial data and photo images.

This paper presents a mews event reenactment system (NERS), which generates virtual character animations in a quick and convenient manner. Thus, NERS can be used to produce computer graphics(CG) scenes of news events that are hard to photograph, such as fire, traffic accident, cases of murder, and so on. By using plenty of captured motion data and CG model data this system produces an appropriate animation of virtual characters straightforwardly without any motion capturing device and actors in the authoring stage. NERS is designed to be capable of making virtual characters move along user-defined paths, stitching motions smoothly and modifyingthe positions and of the articulations of a virtual character in a specific frame. Therefore a virtual character can be controlled precisely so as to interact with the virtual environments and other characters. NERS provides both an interactive and script-based (MEL: Maya Embedded Language) interface so that user can this system in a convenient way. This system has been implemented as a plug-in of commercial CG tool, Maya (Alias/wavefront), in order to make use of its advanced functions

With the awareness that the world market of animation industry is large enough to be concerned as our next generation industry and worthy enough to invest our resources, many animated films have been made and are still being made in these days. These animated films are no more a OEM based production that Korean animation industry have depended on for a long time. This is very positive situation we make our own animated films from plaining to final output. Nevertheless one thing we should aware here is these animations are behind in quality and contents compared to those in advanced country. There should be many reasons in this matter, but the most fundmental problem that the Korean animation industry is facing is lack of its central force like Walt Disney in United States. This study will research the problems of our animation production system and show alternative plans by comparing and analyzing those in advanced country.

The object of this study is to find ways of a creation and an usage of cultural contents, based on the survey of the culture archetype facts, the culture elements and the narrative structure of 'Geotagi folk tale'. This story takes its place as our cultural archetype, because of its perfect narrative structure and the myth-like features in the story line. Additionally, various cultural elements implied in the text have the world wide universality as well as the unique traditional characters of Korea. Thus, for above reason, 'Geotagi folk tale' can be helpful in creating the new cultural contents. In creating and using the cultural contents of 'Geotagi folk tale', the first way is to build up the Digital contents including the data base of the original text and others, and the creation of graphics. The second way is to create the story bank utilizing hypertext. The third way is to make flash animations or games concerning the folk tale. and the fourth way is to to develop the symbols of the folk tale as animation characters.

Most designers use professional 3D animation tools such as 3DS MAX to manually create animation. This manual method requires a great deal of time and efforts, and does not allow animation characters to interact with one another. In this paper, we design an AI middleware of form as 3DS MAX plug-in to solve these issues. We present an AI expression structure and internal processing method for this middleware, and the method for creating AI character's structure. It creates AI character's structure by drawing figures and lines for representing AI elements. For experiment, we have produced same animations with the traditional method and our method, and measured the task volume in both methods. This result verifies that the task volume is similar or higher than the traditional method in small-scale tasks, but up to 43% of the task volume is reduced in large-scale tasks. Using the method proposed in this paper, we see that characters in an animation interact each other, and task volume in large-scale tasks are reduced.

Currently, Virtual Reality video content is rapidly increasing in number of users due to the rapid growth of related hardware and software. Accordingly, Virtual Reality animation is also being produced in a new form by rapidly integrating with Virtual Reality technology among video contents. Currently, research on Virtual Reality animation has focused on how films are produced and how they are directed, and no research has been done to organize the pipeline for efficient VR animation production. Therefore, this study drew the characteristics of the pre-render VR animation pipeline by comparing it with the production pipeline of the existing 3D animation to produce the VR animation efficiently. Through this, we presented organic integration of production and post production processes suitable for the production of VR animations and reduced rendering time using Render Pass for efficient production.
