Grouping of characters in a 3D game can be very effective to play. An 3D game characters grouping method is proposed using Object Feature vector depending on their characteristics. In the case of NMT, the constitution of pattern is regular and directive. But MT is not. Such characteristic is extracted using Gabor Filter, then character is grouped. Through experiment, we obtain accuracy of more than 80% for grouping method using each feature. Thus, using this property, characters could be grouped effectively and it draws the game more speed and strategic actions as a result.

This paper studied various low power structures of texture caches for mobile 3D graphics accelerator to reduce the memory latency of texture data. Also the paper designed the texture cache with the variable threshold values of power mode transition according to the filtering algorithms. In the trace driven simulation, we compared the performance of those structures using Quake game engine as the benchmark. Also the algorithm was proposed and verified by the simulation, which has variable threshold values of power mode transitions according to the selected texture filtering method.

DirectX Graphics plays the role of hardware independent 3 dimensional drawing interface for 3 dimensional video display. However the APIs in DirectX Graphics provide not only small improvement in velocity in the lowest level but also unstable performance of velocity according to their usages. In this paper, we present the structure of 3D game engine of efficient performance and describe functions and implementational features of game engines for an efficient 3D rendering in the environment of DirecX Graphics.

A 3D game plays in fast screen conversion and the objects a partner with camera visual field. Shall recognize a threat of the opponent objects that there is not to a visual field of a player in on-line games. In this paper, we proposed a method to efficiently search for the object in 3D game as used modified frustum culling. For the objects which a player cannot perceive, we accord the player and camera position and used a distance of the player and objects for count of the threatening objects. The method that proposed will play an important role in development of a 3D FPS games.

Recently attention deficit of children has caused various social problems. Those children who has symptoms like ADHD (Attention Deficit/Hyperactivity Disorder) has to be provided with methods which can enhance their attention level in a child-friendly way such as 3D games. This paper shows a research on how to measure the level of attention for attention deficit children using their favorite 3D games. Firstly, we speculated on the methods about attention measurement used in the medical area. And then we searched measurement variables which can effectively evaluate the level of attention during a game play time. Secondly, we have conducted experiment whether there exists difference about the value of the measurement variables between the two groups, normal children group and attention deficit children group. Those variables are omission error, commission error, average response time, and standard deviation of response time. Though our experiment has only been limited to visual attention level, four measurement variables revealed mutual differences.

Application field of third dimension graphic is becoming diversification by the fast development of hardware recently. Various theory of details technology necessary to design game such as 3D MMORPG (Massive Multi-play Online Role Flaying Game) that do with third dimension. Cyber city should be absorbed. It is the detection speed that this treatise is necessary in game engine design. 3D MMORPG game engine has much factor that influence to speed as well as rendering processing because it express huge third dimension city´s grate many building and individual fast effectively by real time. This treatise nay get concept about the collision in 3D MMORPG and detection speed elevation of game engine through improved detection method. Space division is need to process fast dynamically wide outside that is 3D MMORPG´s main detection target. 3D is constructed with tree construct individual that need collision using processing geometry dataset that is given through new graph. We may search individual that need in collision detection and improve the collision detection speed as using hierarchical bounding box that use it with detection volume. Octree that will use by division octree is used mainly to express rightly static object but this paper use limited OSP by limited space division structure to use this in dynamic environment. Limited OSP space use limited space with method that divide square to classify typically complicated 3D space´s object. Through this detection, this paper propose follow contents, first, this detection may judge collision detection at early time without doing all polygon´s collision examination. Second, this paper may improve detection efficiency of game engine through and then reduce detection time because detection time of bounding box´s collision detection.

The process of developing a online 3D game engine involves designing details of the engine, alpha test, adjustment, supplementation, beta test and introduction, and an online 3D game engine is made of a server engine and client engine. The server engine, which is made of server construction part, distribution center and DB construction part for building asymmetric multiple servers, is developed by Linux, and the client engine, which is made of a graphic part, sound part, AI part and object management part, is developed by using DirectX in Windows, and it proposes an engine configuration and method based on 3D engine technology by analyzing the network technology, which is a common engine technology.

국내외로 수많은 게임개발자들이 이용하는 Unity 3D 엔진을 이용한 게임들을 제작 하였다. Unity 엔진이 많이 쓰이는 이유 중 하나는 복잡한 알고리즘을 코딩해야만 구현 할 수 있는 기능을 컴포넌트 형식으로 지원해줌으로써 개발을 좀 더 수월하게 진행할 수 있기 때문이다. 탈출 게임을 개발하려면 일단은 컨셉에 맞는 요소들을 만들어야 할 것이고 또한 탈출 게임의 기능들을 수행할 스크립트 구현을 하는 것 또한 매우 중요하다. 본 논문에서는 게임 엔진 내에 있는 기능들을 이용하여 탈출 개발 과정에 대해 소개한다.
