Interests to cultural prototype as a material of cultural contents are getting more increasing nowadays. One of them is myth. The important thing when you are dealing with the myth as the material that how to convert prototype narratives. Today, digital culture is becoming one of the essential elements of mankind, that is a new sociocultural phenomenon and distinguishing differentiation from the past analogue era. In this regard, the combination of mythology and digital culture is effective strategies for transforming storytelling that can resonate with people who are not familiar with myths. puts the view both of this world and underworld, mythical characters, and various elements of the Grim Reaper into the story. And combines them with digital elements. sets the world that the transcendental soul exists as physically transferred data form. and reinterprets the traditional mythology world into the digitally operated world. Soul-Phone from this anime reflects the digital culture such as storage and transmission, and helps enjoying audiences accept the unfamiliar world of myth. And also It symbolically shows dystopian viewpoints through side effects can caused by digital technology development, such as the instrumentalization of human being, the risk of communication through digital media, and ego-loss caused by duplication, etc. In conclusion, forms a consensus with the audience through the transformation strategy of storytelling that converts the world of myth into the digital world. And it reflects the dystopian view and shows a differentiated world view from the narrative of myth.

Illusion played by mutual communication in Interactive Media Art is studied in this thesis from the narrative point of view, not from the entertaining point of view. Microscopic narrations founded in screen changes are analyzed by traditional narrative factors such as plot, point of view, narration, time creating the identity of Interactive Media Art. Traditional narrative factors in consequence have been converted to different forms after being combined with the features of Interactive Media Art. Plot has been converted to fragmentary plot and creators' point of view in many work pieces has been recreated to the outside participants' point of view. Also, creators' narrations described from various points of view has transferred to participants' narrations based on physically spacious search. Times of the present sharing with the past are observed in Interactive Media Art, too. It is concluded that audience's active participation through mutual communication makes an influence on the change of essentially traditional narrative factors. Moreover, the factors mentioned in this thesis are regarded as the unique identity of out of various kinds of modern media art.

Natural Phenomena are simulated to make computer users feel verisimilitude and be immersed in games or virtual reality. The important factor in simulating fluid such as water or sea using 3D rendering technology in games or virtual reality is real-time interaction and reality. There are many difficulties in simulating fluid models because it is controlled by many equations of each specific situation and many parameter values. In addition, it needs a lot of time in processing physically-based simulation. In this paper, I suggest simplified fluid-surface model in order to represent interaction between rigid body and fluid, and it can make faster simulation by improved processing. Also, I show movement of fluid surface which is come from collision of rigid body caused by reaction of fluid in representing interaction between rigid body and fluid surface. This natural fluid-surface model suggested in this paper is represented realistically in real-time using fluid dynamics veri similarly. And the fluid-surface model will be applicable in games or animation by realizing it for PC environment to interact with this.

We propose an inter-leg collision avoidance method that compensates the disadvantage of the data-driven biped control method. The data-driven biped control technique proposed by Lee et. al [1] sometimes generates the movement that the two legs intersect with each other while walking, which can not be realized in walking of a real person or a biped robot. The proposed method changes the angle of the swing hip so that the swing foot can move inward only after passing the stance foot. This process introduces an additional angle adjustment algorithm to avoid collisions with the stance leg to the original feedback rule of the stance hip. It generates a stable walking simulation without any inter-leg collisions, by adding minimal changes and additional calculations to the existing controller behavior.

This paper proposes a real-time simulation technique for thin shells undergoing large deformation. Shells are thin objects such as leaves and papers that can be abstracted as 2D structures. Development of a satisfactory physical model that runs in real-time but produces visually convincing animation of thin shells has been remaining a challenge in computer graphics. Rather than resorting to shell theory which involves the most complex formulations in continuum mechanics, we adopt the energy functions from the discrete shells proposed by Grinspun et al. For real-time integration of the governing equation, we develop a modal warping technique for shells. This new simulation framework results from making extensions to the original modal warping technique which was developed for the simulation of 3D solids. We report experimental results, which show that the proposed method runs in real-time even for large meshes, and that it can simulate large bending and/or twisting deformations with acceptable realism.

In this paper, we suggest a method to simulate high-quality iguana animation by using low-quality motion capture data. Iguana motion data captured using a small number of markers cannot express its movement precisely, and even with a realistic skin mesh, it shows unnatural movement because of limited degrees of freedom. In order to solve this problem, we propose to simulate a natural and flexible movement by applying a soft-body simulation technique which models the movement of an iguana according to muscle forces and body's elastic forces. We construct a motion graph from the motion capture data to describe the iguana's various movements, and utilize it to select appropriate movements when the iguana moves. A target point on a terrain is set from the user's input, and a graph path is planned based on it. As a result, the input movement of iguana walking on a flat ground transforms to a movement that is adapted in an online manner to the irregular heights of the terrain. Such a movement is used to calculate the ideal muscle lengths that are needed for soft-body simulation. Lastly, a tetrahedral mesh of the iguana is physically simulated to adapt to various situations by applying a soft-body simulation technique.
