Recently, almost games are using the 3D environment. Therefore, it required strongly that well-structured 3D engine or tools for development of some complicate 3D applications efficiently. In this paper, we design and implement a 3D engine (PLay engine) using the DirectX 9 SDK of the Microsoft corporation. The PLay engine has independent module structure, which has object oriented characteristics. and has not only 3D rendering functions but efficient algorithms. Moreover, we implement some tools what has compatibility with our engine for convenience. Therefore, it helps development of a 3D application easily and efficiently. We also describe each module with 2-layer structure, and each tool with compatible module, and make a simple game using PLay engine for testify.

This study was designed to investigated children's spatial cognitive skills as based on their practice with computer games. The sixty children were divided into 3 groups there were twenty children in experimental group 1 (the geometric game experimental group), twenty children in experimental group 2 (the arcade game experimental group), and twenty children in the control group. The sSpatial cognitive skills of the children were assessed according to by visual speed, mental rotation, and spatial visualization tasks. The rResults showed that computer game practice enhanced the children's spatial skills (visual speed, mental rotation and, spatial visualization). The c Children's mental rotation and spatial visualization showed a significant difference with the type of computer game.

Sound contents of these days are in the trend of 3D surround audio which has much higher quality then CD audio with the aid of DVD, Development environments of sound contents should be advanced and the efficient application of this system is quite necessary. In this paper, we proposed an improving method for utilizing sound/audio card systems which are necessory for developing game and multimedia sound contents as well as relate know-hows of producing 3D sounds with sound production tools for their efficient usages and applications.

세계 게임시장의 급속한 팽창으로 인하여 게임 S/W의 경쟁력 확보를 위한 여러 방안들이 제기되고 있으며 이중 품질에 대한 논의가 대두되고 있다. 그러나 게임 S/W의 품질에 관한 국내의 연구 개발이 아직 미흡한 실정이며 게임 S/W의 품질저하로 이어지고 있다. 따라서 게임산업의 발전과 아울러 패키지게임 S/W의 품질 향상을 통해 게임 S/W의 질적 수준을 제고할 필요가 있다. 본 연구에서는 ISO/IEC 9126를 기반으로 패키지게임 S/W를 시험하여 결과를 산출할 수 있는 품질모델과 시험기법를 개발하여 패키지게임 S/W 품질평가에 적용할 수 있도록 하였다.

In games, immersion is the most important factor that makes the player play game continuously. The user's inability to immerse in game makes him/her not interested in game, so it makes the user give up. So, we must perceive the immersion factor that the games have. By applying the factors that causes immersion to the game development, we will be able to multiply the joy of game to the user, and bring high profit to the game developing enterprises. To this, this study finds out the interrelations between the factor of immersion existing inside the game and the components of the game to experience the highest immersion status to the user.

This article inspected 16 game rating systems in the world to find out the trends of those. Mainly the perspective of freedom of expression is used to find out the implications of the trends. As the position of game becomes higher, the increase of game specialty rating institutions, the augmentation of self regulations rating institutions, the enlargement of freedom of expression in the area of game are revealed as trends. These trends are in the natural order of events that match with the development of game. We could know that rapid change and innovation is much needed.

The use of the A* for the path search of the agent in the game map gives the computational overhead in real time game processing. To solve this problem, the route table was presented for the 2D game This route table is made in the game development phase and utilized in game playing. The route table designed for 2D game is extended for 3D game in this paper. But the memory space is required too much. This Problem can also be solved using the data compression by skipping the duplicated route table.

We propose guidance laws based on a pursuit-evasion game. The game solutions are obtained from a pursuit-evasion game solver developed by the authors. We introduce a direct method to solve planar pursuit-evasion games with control variable constraints in which the game solution is sought by iteration of the update and correction steps. The initial value of the game solution is used for guidance of the evader and the pursuer, and then the pursuit-evasion game is solved again at the next time step. In this respect, the proposed guidance laws are similar to the approach of model predictive control. The proposed guidance method is compared to proportional navigation guidance for a pursuit-evasion scenario in which the evader always tries to maximize the capture time. The capture sets of the two guidance methods are demonstrated.

In the recent development of 3D game, the importance of the game interface as well as the amusement and performance of the game is highlighted. Considering the fact that the flash can easily express the various multimedia contents will provide new possibilities and improve the presentation of game interfaces, the system using the flash in 3D PC game interface was designed and tested in this paper.
