The procedural generation algorithm is an algorithm that automatically generates a content to be used in a game by repeatedly executing a series of rules. As the size of the game increases, the amount of content used in the game increases. Accordingly, artificial intelligence research is actively conducted to automatically generate game contents using game artificial intelligence such as procedural generation. In this paper, we propose an algorithm to create 3D game world using procedural generation. The proposed algorithm generates a two-dimensional contour in which the path is naturally connected using Perlin-Noise whose noise is gradually changed. A three-dimensional Height-Map is created based on the generated two-dimensional contour lines. The generated Height-Map show that the shape of the map is normal and that the player is able to move around all the sections as in the game world created by hand. In the future, we will improve the performance of algorithms and apply them to game.

With the development of information and communication technology, the demand for indirect experience contents using realistic media is increasing. It is important to keep the overall concept of the models consistently in order to immerse in the contents while watching realistic media. In the case of realistic media that provides an indirect experience of tourist attractions, modeling should be done by reflecting the actual information of the sites in order to provide an accurate experience. In this paper, we propose a three-dimensional modeling method of islands, representative tourism resources of the southern coast, by reflecting actual data. Since the proposed method is performed according to a structured procedure, it makes it easy to maintain the visual consistency of the entire model when several people work together. Implementation results show that the proposed method produces more realistic results than the modeling method using height information simply.

As an interest in metaverse increases, there are many studies to apply virtual reality to indirect experiences. Virtual reality is increasingly being used not only for entertainment such as games but also for educational content. A key technology of indirect experience is modeling an object to provide a realistic experience to the user. Natural environments such as tidal flats change with time, and many living things also live there. In this paper, we propose a method for creating experiential content that accurately models the ecological environment of tidal flats. The proposed method explains how to naturally model the temporal change of tidal flats. We also explain how to model a crab, a creature that inhabits the tidal flat, in the forms of an NPC using the behavior tree. Implementation results show that the proposed method uses simple algorithms but expresses the shapes of tidal flats well.
