본 논문에서는 게임 엔진에서 사용되는 노말맵(Normal Map)의 원리와 그 응용 방식에 대해 연구하였다. 노말맵은 게임에서 하이 폴리곤 모델링에 적용되는 조명 적용 데이터를 로우 폴리곤에 적용할 수 있는 기술로, 하이 폴리곤 모델링의 벡터 방향 데이터를 텍스쳐로 저장하여 로우 폴리곤에 적용해서 벡터 방향을 텍셀단위로 조정할 수 있게 한다. 여기에서는 게임에서의 노말맵 저장 방식과 연산 방식에 대해 소개하고 이를 응용하여 최적화 시킬 수 있는 방법에 대해 연구한다.

The learning by computer games, is in the spotlight as an effective education method for the game generation. The educational games need to provide additionally an omniscient view of the learning as an objective viewpoint for storytelling of learning. The omniscient viewpoint needs good readability in real-time, and to provide systematically overall and detailed informations of learning. In this paper, we propose the visual learning map as the omniscient view for storytelling of learning. The proposed learning map is composed of the district map, the topic map, and the progress map for the omniscient view of the learning. The proposed learning map is represented by several visual diagrams for real-time readability. The proposed learning map can apply to all the educational games which provide the game minimaps.

The maps in the world of the role playing games provide not only areas for motions and actions of player characters, but also worlds of totally included monsters and NPC(Non Player Character). However, the design of maps and monsters in them could not be tested for their balances until the games had been developed quite a bit. So they need additional expense of extension period of developments. In this paper, we have designed and developed a map simulator to expect the popularities of the maps in the early stage of the game planning in order to prevent inefficient concentration of users on some maps by expecting the popularities of the maps in the early stage of game planning and by setting the parameters of monster arrangements in the map.

맵에디터(map editor)란 게임에 사용될 게임환경을 저작하는 도구로서 게임의 무대가 되는 지형을 생성하고, 게임에 사용되는 다양한 건물이나 주인공, 몬스터 등을 객체를 배치하는 등 게임 환경의 변화를 눈으로 보면서 손쉽게 저작할 수 있도록 한다. 뿐만 아니라 게임 객체 혹은 지형의 여러가지 속성을 설정해 게임에 그 값을 반영토록 하는 기능을 제공하기도 한다.

게임 인공지능에서 경로 찾기는 매우 중요한 분야이다. 캐릭터나 NPC(Non Player Charater)가 목적지까지의 경로를 탐색하기 위해서는 복잡하게 구성된 게임 맵에서 오브젝트나 벽 등의 장애물을 회피하면서 가능한 최단 경로를 찾아야 한다. 기존의 일반적인 경로 찾기 알고리즘은 캐릭터의 움직임이 자유로운 간단한 게임 맵에서는 전역 최소해 탐색이 가능하다. 그러나 다양한 오브젝트 등이 배치된 큰 규모의 게임 맵에서는 캐릭터가 목적지까지의 경로를 탐색하는 과정에서 지역 최소해(Local Minima)로의 수렴이 발생함으로써 이를 탈피하는 것이 어렵고, 결국에는 목적지까지 도달하지 못하는 상황이 발생하게 된다. 본 논문에서는 이러한 기존 경로 찾기 알고리즘의 단점을 해결하기 위해 시뮬레이티드 어닐링 알고리즘을 제안하였다.

Recently, there is a growing consideration that game authoring tools can play an important role in producing 3D games. In this paper, we introduce our 3D game authoring tool. The tool consists of a map editor, a sound editor, a game data exporter/previewer, and a special effect editor. This tool can help a game designer Produce game data such as game maps, sound effects, and special effects, and so on. In this paper, we implemented a prototype game content to verify the effectiveness of the developed authoring tool.

Game environment, game map and background graphic design is very important elements and factors that support fun, look & feel, immersion and player's acting fields. In this paper we defined elements of game background environment. And then make an investigation and refer to sundry records and books, we described elements of periodic environments, historic environments, natural environments, artificial environments, cultural environments, virtual environments, weather environments. Especially, the study suggests the model of game environment desgin to apply game map and game background graphic design.

Outdoor ads such as billboards, banners or posters frequently appears in street maps of FPS games. In this paper, we propose a method for the automatic placement of outdoor advertising in the city area of FPS games. Outdoor ads are from real world products or enterprises and they are managed in a server computer. If the ads data are updated, the advertisements are automatically placed again without modifying source codes. When placing ads, we utilize the real world location of the game player regarding commercial spheres of ads and service types of real world shops. We evaluate priority scores for the available ads based on the collected real world properties and higher priority ads are preferentially placed on the map. The proposed ad placement method makes the game players feel affinity for the placed ads and also it increases the advertising effect.

Multiple layer displacement mapping methods are able to represent more complex and general geometries which cannot be presented by single layer displacement mapping methods, and provide a realistic scene to digital contents such as 3D games and movies with relatively low costs. However, as we use more layers for details, data space is wasted more because lower layers have less displacement data than higher layers. In this paper, we suggest a lossless compression and rendering method of a multiple layer displacement map. Since we compress the map without data loss, the proposed method provides the same quality as the rendering result that uses an original multiple layer displacement map.

In this paper we suggested a map management method for on line RPG supporting full 3D. In general, it is possible to support full 3D with client engine. Rut the online game server cannot show the expected performance under normal price constrains with current hardware technology, since the amount of data for management of 3D on-line game server increase exponentially with respect to the size of game world. To solve this problem. we introduced the "special object" which makes it possible for on-line game server with low performance hardware. This suggested method gave concrete from to manage full 3D for server as well as clients.s clients.
