As the visual effect frequently used in movies or animations, special effects are well suited for the creation of buildings or materials' destruction and collapse scenes. With the relevant programs developing technologically, the adoption of a real-time physically based-system makes it possible to realistically express dynamic simulations. In the large scale, the visual expression of such effects of destroying is satisfying enough, but most common programs of those effects fail to maximize visual effect generated with the cutting of small materials. Besides, to perform a heavy simulation process needs high-performance hardware and programs, where high costs would become a serious issue. For this reason, this paper suggests a solution optimized for the effect of small materials-cutting. The progress of each step shows technologies which trace movement with the state of the completion of the character's motions and then cut the material in real-time, finally led to the very realistic visual effect. Besides, using vector inner calculation to follow the motions of object and to realize cutting effect, this study provides an experiment that constructs visual effect for visualization from the basis of mathematical algorithm and it would be certainly as an educational material used for further researches.

The needs for visualizing interactive multimedia contents on portable devices with realistic three dimensional shapes are increasing as new ubiquitous services are coming into reality. Especially in digital fashion applications with virtual reality technologies for clothes of various forms on different avatars, it is required to provide very high quality visual models over mobile networks. Due to limited network bandwidths and memory spaces of portable devices, it is very difficult to transmit visual data effectively and render realistic appearance of three dimensional images. In this thesis, we propose a compression method to reduce three dimensional data for digital fashion applications. The three dimensional model includes animation of avatar which require very large amounts of data over time. Our proposed method utilizes temporal and spatial coherence of animation data, to reduce the amount. By grouping vertices from three dimensional models, the entire animation is represented by a movement path of a few representative vertices. The existing three dimensional model compression approaches can get benefits from the proposed method by reducing the compression sources through grouping. We expect that the proposed method to be applied not only to three dimensional garment animations but also to generic deformable objects.

Costume play is an act of imitating the appearance or behavior of characters in digital games, cartoons or animations. In recent years, cosplay culture has become popular in China as the digital game is made into a movie. The number of cosers has also increased. Especially, Qiwei Zoe has been very popular among cosers because her cosplay photography reflects the understanding of the cosplay culture. A number of cosers admit that her work shows a commercial and artistic potential of cosplay photography. This paper analyzed how she maintains the contents of the original but creatively reimplementing them. She shoots the fantastic image of the character like it really exists in reality so that she can avoid excessive editing work. She emphasizes the character's action that symbolizes its personality and utilizes a variety of outdoor shooting locations similar to the original scenes. We also discussed how cosplay photographers can create cosplay photography by maintaining its artistic features.

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.

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.

The development of technology in traditional media is affecting a variety of ways. In particular, the influence of digital images, the animation turned to a realistic 3D animation. With the release of realistic 3D animation , Robert Zemeckis received much attention but the audience did not like the animation of this style gradually. Robert Zemeckis gave up 3D animation after that drew attention for having a huge production budget while failing at a record-setting proportion in the American box-office. A digital actor in realistic 3D animation looks like real but the audience know that it is not real and they know that realistic 3D animations and live-action movies are different. So the audience will experience an emotional conflict like confusion, hesitation. The visual completion in realistic 3D animation is due to the development of technology and technology must develop to connect the audience acceptance and movie.

This study investigated the effects of an Augmented Reality(AR) implemented book on flow of reading, interest in history, and acquisition of history knowledge. Perceptions of AR infused books were investigated as well. Researchers provided a history book implementing AR and the same book without any AR content respectively to an experiment group(n=15) and a control group(n=15) composed of $3^{rd}$ and $4^{th}$ grade elementary school children. Results indicate that AR implemented reading had a positive effect on the flow of reading and interest in history, but not on acquisition of history knowledge. Also, AR-based contents were attractive to learners due to its amusing characters, sound, realistic visual motions, and vivid three-dimensional effects. Lastly, students preferred amusing interesting characters, lengthier animations and subtitles, and AR that could be seen without holding smart devices for a long while.
