In general, simulation is to predict or evaluate some systems that are hard to be executed in real world, and so usually the target systems to be modeled are large and complex. Trying to observe the dynamics of the systems results in similar level of animation complexity, the model and animation has the same complexity as the system. Trying to display all the graphic objects representing the dynamics of the models being simulated, however, causes the distraction of focus, which results in solving the above listed problems difficult. The redundant graphic objects also increase the computer computation overhead. To solve the problem, a research about a hierarchical animation environment has been proposed a few years ago. In the research, the users can have better focus on the dynamics of system components by selectively choosing the hierarchical level and components within a level of the hierarchically structured model. However, the research has not a modeling methodology for modelers to describe systematically animation part corresponding to dynamics of simulation in a model. This research has defined the modeling methodology of DESHA and defined DESHA-C++, improving the previous research output, as an execution environment of DESHA models. In addition, to use hierarchical animation environment in various problems, this research proposed and developed the distributed simulation modeling environment that connects DESHA environment and HLA.

The advancement of technology enables smart phones or handheld devices to render complex 3D graphics. However, the processing power and memory of smart phones remain very limited to render high polygon and details 3D models especially on games which requires animation, physic engine, or augmented reality. In this paper, several techniques will be introduced to speed up the computation and reducing the number of vertices of the 3D meshes without losing much detail.

As the LED or LCD technology has been developed, if we use LED or LCD pannel, more wide color range coluld be obtained as CRT monitor. Specially, full color LED display is developed by high brightness blue LED. It can be applicable to display pannel with a long-life, wide visible angle and high brightness. A display pannel shows the images of CRT monitor performed by the main computer. Graphic application in the main computer is therefore more important in the market. Conventional 3D STUDIO, one of graphic softwares, has difficulties in manipulating and understanding the specific terminology so that one may need more time to learn it. We, therefore, developed graphic application which can recycle the conventional 3D images by creating or editing the image easily.

The purpose of this research was to develop the method of media literacy education program based on animation production for the 21 century student. A total of four stages of educational programs were constructed by linking the media literacy education goals and the animation production process through the previous research. First, Acquisition of animation production tools for enhancing media access capability. Second, Animation production practice stage for strengthening creative production capacity. Third, the development of critical understanding stage for presentation and discussion the results. Forth, social sharing stage to strengthen social communication capacity. For the practical application of the education program, it was produced as an educational model for Hanseo University animation summer camp, and was educated by 79 middle school students in Chungcheong province. Based on this research, students improve an analytical ability and help them become active participants by creating their own animations. In future, it will be needed a continuous research on the development of educational programs using various media.

The active use of motion graphic in the production of digital movies contents is a significant way to deliver the contents' messages clearly and intensely. The analysis of film expression characters of digital movies contents based on the motion effect provides a good tool to present an effective method for the production of films using motion graphic. Motion graphic, which can animate motionless movies and graphic images dynamically, is now used as an excellent tool in the editing of digital movies. So, this study aims to show systematically the expression characters of digital movies contents by using the production of films of motion graphic. It also aims to suggest an efficient production of films by analyzing major contents produced with motion graphic and after that examining their types and skills according to the genres and times.

As increasing emphasis is being placed on user experience design, the RIA technology is widely deployed for user interface and software operation on embedded devices including cell phones and TVs. In particular, RIA-based IPTV enables creation of various interactive contents via sophisticated animation and various input devices. This paper proposes a service framework for emotional contents on broadcast and communication-converged IPTV systems. We design a programming interface extension for IPTV-based flash contents and develop a prototype of flash runtime with the extended programming support. Since the proposed runtime was carefully designed to fully utilize the built-in graphic acceleration hardware in media processor, it supports high resolution graphic animation in resource-constrained IPTV environments.

This research describes render pass synthetic techniques required to use for the effectiveness of them in 3D animation synthetic technology. As the render pass is divided by property and synthesized after rendering, elaborate, rapid synthesis can be achieved. In particular, occlusion pass creates a screen as if it had a soft, light shading, expressing a sense of depth and boundary softness. It is converted into 2D image through a process of pass rendering of animation projects created in 3D space, then completed in synthetic software. Namely, 3D animation realizes the completeness of work originally planned through compositing, a synthetic process in the last half. To complete in-depth image, a scene manufactured in 3D software can be sent as a synthetic program by rendering the scene by layer and property. As recently the occlusion pass can express depth notwithstanding conducting GI rendering of 3D graphic outputs, it is an important synthetic map not omitted in the post-production process. Nonetheless, for the importance of it, currently the occlusion pass leaves much to be desired for research support and books summarizing and analyzing the characteristics of properties, and the principles and usages of them. Hence, this research was aimed to summarize the principles and usages of occlusion map, and analyze differences in the results of synthesis. Furthermore, it also summarized a process designating renderers and the map utilizing the properties, and synthetic software usages. For the future, it is hoped that effective and diverse latter expression techniques will be studied beyond the limitation of graphic expression based on trends diversifying technique development.
