3D character animation grow rapidly with the development of computer graphic technology and software. Nowadays 3D character animation holds a important position in the various industry fields including movie, advertisement, animation, and game. With the rapid growth of computer graphic, real time animation of complex characters as well as high quality rendering, which was impossible before, are now prevailing. What is remarkable in this growth is the appearance of virtual idol. The virtual idol plays a leading role in 3D character animation and has a synergy effect in the field of fancy and theme park industry. The aim of this inquiry is to examine the status of computer graphic skill and media related to the 3D character animation to search out the problems in the fields and to propose the solution of the problems

This study was aimed to analyze the disparities of 3D stereoscopic images in four well-known American animation movies. After Avatar (2009), lots of stereoscopic movies were developed in Korean 3D production. Almost all 3D productions in Korea, however, focus on the display images or TV series animation yet. In order to make many well-made Korean stereoscopic 3D animations in future, analyzing and comparing the disparities of 3D stereoscopic images is necessary and even mandated. First, I chose 40 cuts from each four American stereoscopic 3D feature films, including Despicable me 2, Epic, Monster University, and Turbo. According to the classifications of shot angles by Vineyard (2008), secondly I analyze the 23 different angular disparities of 3D stereoscopic images and displayed in tables. Demonstrated shot angle disparities in each scene would provide numerical information to animators how to design and make the 3D stereoscopic images. Making successful stereoscopic 3D feature film will be a huge turning point in the Korean animation field in future. This study would be a first trial to seek a new method to set ahead an outlook of numerical values of 3D stereoscopic images for better visual effects.

This paper designed 3D animation in consideration of young children's characteristics to stimulate their interest and to be more understandable to them. It was also confirmed that, using the 3D animation software, young children came to recognize the problem of environment pollution and developed desirable attitude and behavior fur protecting the environment. Furthermore, this paper suggested the derection of systematic environmental education at kindergartens and other early childhood education institutions using the developed 3D animation software as a leaching material.

The world being made by computers showing great expanses and complex and various expression provides not simply communication places but also a new civilization and a new creative world. Among these, 3D computer graphics, 3D animation and virtual reality technology wore sublimated as a new culture and a new genre of art by joining graphic design and computer engineering. In this study, I tried to make a diagnosis of possibilities, limits and differences of expression in the area of virtual reality computer graphics animation as a comparison between camera action, angle of actual still camera and film camera and virtual software for 3D computer graphics software - Maya, XSI, Softimage3D.

Recently, the importance of the efficient production pipeline design has been increased for 3D animation, which becomes more delicate. In this paper, we propose 3D animation character development pipeline using 3D printing technology. We introduce 3D printing procedure into each step of the classical 3D animation and character development pipeline to incorporate the feed-back from the designer immediately. Specially, during the production step, we can find the design errors and minimize the period of production by using 3D printing of approximate shape of designed character. Using proposed method, eight DreaMegg characters were developed and their quality was very high with respect to 3D virtual graphics and real product. Using our method, high-quality 3D animation character can be developed with the minimized time and cost for development by reflecting the feed-back into production line from designers and researchers immediately.

With the success of the world's first 3D computer animated film, "Toy Story" in 1995, industrial development of 3D computer animation gained considerable momentum. Consequently, various 3D animations for TV were produced; in addition, high quality 3D computer animation games became common. To save a large amount of 3D animation production time and cost, technological development has been conducted actively, in accordance with the expansion of industrial demand in this field. Further, compared with the traditional approach of producing animations through hand-drawings, the efficiency of producing 3D computer animations is infinitely greater. In this study, an experiment and a comparative analysis of markerless motion capture systems for facial expression animation has been conducted that aims to improve the efficiency of 3D computer animation production. Faceware system, which is a product of Image Metrics, provides sophisticated production tools despite the complexity of motion capture recognition and application process. Faceshift system, which is a product of same-named Faceshift, though relatively less sophisticated, provides applications for rapid real-time motion recognition. It is hoped that the results of the comparative analysis presented in this paper become baseline data for selecting the appropriate motion capture and key frame animation method for the most efficient production of facial expression animation in accordance with production time and cost, and the degree of sophistication and media in use, when creating animation.

Rapidly changing 3D rendering technology is expanding its fields of display fast towards Non-Photorealistic Rendering beyond Photorealistic Rendering. It is now attainable to realize conventional 2D visual animated cartoons with 3D animation technology. It is not complex to create two shades of color or more with the rendered outcomes, made by Toon-Shading, of 3D total packaging animation Maya with black outlines brought through the process of 2D animation. It the reality of 3D animation being one of the prevalent mechanisms of animated films, it is valuable for familiarized animated cartoons to be realized by the technology of 3D animation. Thus, I hope to help in many ways create more effective 3D cartoon animation production process by optimized Toon-Shading attributes method and technology in this research.

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.

For real-time animation, keyframe animation that consists of translation, rotation, scaling transform nodes is used widely in 3D graphics. This paper presents geometrical watermarking using vertex coordinates in CoordIndex node and interpolator watermarking using keyvalues in PositionInterpolator node for 3D keyframe animation based on VRML. Experimental results verify that the proposed algorithm has the robustness against geometrical attacks and timeline attacks as well as the invisibility.
