My artwork, '1000 years', in the form of an animation film has been exhibited in the '2011 Haein Art project' of a special exhibition at the Haeinsa monastery compound. The '1000 years' represents the marvels of sacredness and Buddhist symbols using the surrealist expression of computer animation. This paper would argue how Buddhist idea can be explored by the surrealist expression of 3D computer animation. In the light of this, animation and surrealist expression will be reviewed by the epistemological approach and based on this, I would attempt to reveal how this computer animation film represents the meaning of Buddhist symbols which exist in the monastery compound. This research is processed by the case study related to my artwork as the form of art practice based research.

The motion base to a film used in 4D cinema theaters or theme parks is different depending on the operator's control or hardware system and this causes inefficiency in management of the theater. There are several different simulation software on the present market, but these are difficult for an animation producer to use them. This study introduces the idea in which a film producer simulates the movement of the motion base by using computer graphic animation tools mostly adopted by production for creating 3D animation and motion control data. Maya and 3D Cross were used to show the path of a motion camera visually. Attitude and axis control data were extracted from the movement of the virtual motion base and were used to control a prototype of the motion base. As a result, the motion control data from computer graphic animation tools can be created so that a film producer can create standard motion control data independently regardless of the hardware and operator's skill.

The role of sound in producing 3D animation clip is one of the important factor to maximize the immersive effects of the scene. Especially interaction between video and sound makes the scene expressions more apparent, which is diversely applied in video production. One of these interaction techniques, the out-focussing technique is frequently used in both real video and 3D animation field. But in 3D animation, out-focussing is not easily implemented as in music videos or explosion scenes in real video shots. This paper analyzes the sound data to synchronize the depth of field with it. The novel out-focussing technique is proposed, where the object's field of depth is controlled by beat rhythm in the sound data.

The development of computer graphics leads to high value-added products, such as film, game contents, 3D animation. In realistic animation, it is impossible and inefficient to produce the movement of each objects as handwork to display the various behaviors of a lot of characters. So we need the techniques of the crowd animation which presents the movement of objects realistically and efficiently by calculating automatically. In this paper, we designed a modeler which generates the attitudes of objects in crowd behavior animation using information of 3D models. We developed an animation system for crowd behavior which was applied for animation, VR, or games.

Recently, in computer graphics, researches on 3D animations have been very active. one of the important research areas in 3D animation is animation of human being. The creation and animation of 3D facial models has depended on animators' manual work frame by frame. Thus, it needs many efforts and time as well as various hardwares and softwares. In this paper, we implements a way to generation 3D human face model easily and quickly just with the front face images. Then, we suggests a methodology for mesh data simplification of 3D generic model.

The 3D contents are getting more attentions in various areas, such as in movies, advertising, games and exhibition contents. There are many authoring tools for making 3D Models and contents. However, those authoring tools take considerable amount of time to learn and to make 3D contents. In this paper, we propose the 3D model conversion algorithm to make 3D models from 2D pictures drawn on the touch screens or papers. The vertex animation method also proposed for the interactive 3D aquarium. The proposed vertex animation algorithm was tested for virtual 3D water creatures and compared with human-made animation. An Interactive 3D aquarium was implemented by using those proposed algorithms. Thus the simplicity and effectiveness of the algorithms can be applied to diverse industries.

Realistic facial animation research field which communicates with human and computer using face has increased recently. The human face is the part of the body we use to recognize individuals and the important communication channel that understand the inner states like emotion. To provide the intelligent interface. computer facial animation looks like human in talking and expressing himself. Facial modeling and animation research is focused on realistic facial animation recently. In this article, we suggest the method of facial modeling and animation for realistic facial synthesis. We can make a 3D facial model for arbitrary face by using generic facial model. For more correct and real face, we make the Korean Generic Facial Model. We can also manipulate facial synthesis based on the physical characteristics of real facial muscle and skin. Many application will be developed such as teleconferencing, education, movies etc.

The establishment of a production pipeline imported 30 computer graphics is suggested in this paper to improve the efficiency of existing production pipeline of clay animation. The point is that the process of building clay characters that remains labor intensive among the existing procedures is replaced by the process of creating computer generated characters. In order to create characters out of clay by means of 30 computer graphics, a diffuse map and displacement map are made of an oil-based clay according to the UVW coordination of polygon modeling, which is the same color and kind of clay used to make a clay character. In addition, a panoramic HDRI recording system is developed to record the lighting information of shooting environment for miniature sets, which is imported in 3D computer graphic tools as digital light source. On account of the new production pipeline, a hyper realistic rendering image can be produced, and at the same time it improves the traditional pipeline of stop motion animation that is know-how based procedure of a complete artist by the engineering approach to the automatic process.

The dynamic design and evaluation of mechanisms need to be performed in a collaboration or concurrent system in order to shorten the development period of the product. A web-based system is the most suitable concurrent system to promote effective collaboration. In order to develop such a web-based system, Java Applet, which is not restrained by a computer's H/W and S/W, is widely used. This paper introduces a web-based 3D animation system for visualizing the motions of mechanisms. This web-based 3D animation system uses a JAVA Applet program method, which can be operated in a web-browser, and the Open Inventor for Java, which supports 3D graphics. It does not only allows the user to verify dynamic simulation results and design variables through the web, but it also has the advantage of supporting collaboration among a number of users through simultaneous connections.
