Due to the spread of COVID-19, many local governments are burdened with the influx of large-scale tourists. As a climate that values Work-Life-Balance has emerged, interest in individual life and satisfaction is rapidly increasing. In addition, due to the popularity of the metaverse field, many people are increasingly interested in related content. In particular, "Animal Crossing: New Horizons" sold more than 15 million copies in 2020, and is enjoying exchanges of interior design, fishing, and collecting insects here. In line with this trend, this study introduces the development of online fishing games based on Jeju infrastructure. This paper focuses on implementation and development, and in particular, it introduces differentiated games through character animation optimized for developing a topographic model that maximizes the beauty of Jeju Island's topography based on the Unity 3D engine.

A terrain is an essential element for constructing a virtual world in which game characters and objects make various interactions with one another. Creating a terrain requires a great deal of time and repetitive editing processes. This paper presents a 3D terrain reconstruction system to create 3D terrain in virtual space based on real terrain data. In this system, it converts the coordinate system of the height maps which are generated from a stereo camera and a laser scanner from global GPS into 3D world using the x and z axis vectors of the global GPS coordinate system. It calculates the movement vectors and the rotation matrices frame by frame. Terrain meshes are dynamically generated and rendered in the virtual areas which are represented in an undirected graph. The rendering meshes are exactly created and updated by correcting terrain data errors. In our experiments, the FPS of the system was regularly checked until the terrain was reconstructed by our system, and the visualization quality of the terrain was reviewed. As a result, our system shows that it has 3 times higher FPS than other terrain management systems with Quadtree for small area, improves 40% than others for large area. The visualization of terrain data maintains the same shape as the contour of real terrain. This system could be used for the terrain system of realtime 3D games to generate terrain on real time, and for the terrain design work of CG Movies.

This research shows how autonomous character agents work in 3D sports game and its application to advertising. It is a kind of interdisciplinary study between game and advertising. In other words, advertising can be used a beneficiary model in game industry. For the purpose of analyzing the role of agents, 3D table-tennis game and advertising tools are developed. The role of agents is booming up and focusing on the game by their voices and texts. In game, several famous brands are showed up as a mean of advertising. This study analyzed the role of agents and advertising from the game user's position. For validity and reliability of the research, questionnaires were analyzed. As a results, several facts are found. Firstly, the agents worked positively as a game boomer. More than half of the respondents answered the agents are useful for the game. Secondly, the advertising tools showed up on the game are helpful to understand the brand. In other words, the game is contributed to build up the brand image. These kinds of attempts may be significant in that the agents are performed as a parter of functional and woman-oriented game. And advertising brands when placed in the game could play the role of the game item or quest. The proposed method can provide the basic references for developing 3D game as an interdisciplinary study.

The light is the language. Directors have to describe the scene component effectively his intention to configure the scene as an appropriately. After this act of the character, the layout of the props and scene lights will enter to the scene components. Those things help to audiences can understand narrative of work and emotion that producer want to send. Expressing their emotions especially using the lights by adjusting the colors and contrast makes audience to concentrate on work and understand naturally. This lighting technique clearly appears on early year theaters stage of England and Rembrandt's paintings. Properly dividing and controlling the lights dramatically increases the beauty of the work elements to express a variety of emotions such as worries and fear. Therefore, it can be evolve depending on director's intent of using lights on his work. Lights can increase involvement of human emotion through basic features that cognition of object, visualization of space-time and by artistic method in the product. This study will examine the role and how to use lighting to express the proper sentiment based on the narrative of the work. Making research named "Lighting Research of 3D animated film which applying light features to express emotion" previous study and have to combine emotional vocabulary and emotion-based theory for classifying the emotional language that can be applied on 3D animation. And choosing most emotional scene from 3D animation for analyze how they used lighting to expressing emotions. Directors trying to show up about the light role through light method that matched perfectly with an emotional language. Expecting this research work of directing 3D animations light for expressing emotional feelings will be continue successfully.

Due to increased interest in character costumes, the field of animation character costume design is gradually developing into a specialized domain. The costume-making process for animation characters presents many differences from the costume-making process for regular apparel. However, there remains insufficient research on the actual process of making the character costumes used in stop motion videos both in Korea and abroad. The purpose of this study is to establish a costume design process for animation characters. Furthermore, this study presents a case study on the costume planning and making process for 3D stop motion animation characters. The character costume-making process was segmentalized into the following stages: character analysis stage, character modeling stage, and character costume making stage. In the character analysis stage, the investigator analyzed the character's movements, designed the character images, and analyzed the movements and motions of the animation characters. After completing character modeling, this study proposed a method for making the character costume. The style of the character costume was designed, and the structural design reflected the position and size of joints as well as the angle of movements. The patterns of the character costume were produced through dimensional tailoring after measuring the body size of the character. Afterward, the costume was completed after passing through the fitting and revision stages. The clothing material was selected to fit the colors and feelings shown in the illustration. To complete the costume after comparing it with the initial illustration, it was revised based on the assessment of its volume and overall atmosphere.
