In game characters, the direction of character design varies depending on the expression or production method. It is necessary to perform game character personality design by reflecting the importance. This study derives the importance of the game character personality model using AHP for the efficient decision and presents game character personality design check tool. In design elements, the importance of external appearance was the highest in all of style. In personality factors, action in 3D realism, external appearance in 3D animation, and speech in 2D animation were the most important.

Computer game has become the core part of multimedia area in our knowledge and information based society Recently, computer game has been evolving into on-line 3D games which give players more realism from the existing on-line 2D games. We are competitive in developing on-line 2D games. However, we have difficulties in maintaining the competitive edge in the area of 3D game technologies owing to the limited technologies. In this paper, we design and develop Aria Online, an on-line 3D prototype game using Dream3D. The on-line game supports simultaneous connections of multi -users on each game server and full flexibility on user's view.

In developing games, realism is considered as an important factor to increase immersion. To do this, the paper developed 'Jungle Master' game applying the conventional energy model to movement of monsters in RPG. The main scenario of the game is that animals attack each other in order to survive the competition in jungle. While chasing monster : fleeing monster is 1:1 in the conventional energy model, it is extended as n:1 in order to increase fun. As the results, this paper showed that the energy model can be effectively applied to the real game and monsters can be implemented so that they can move in natural.

If the game characters in the cyber world speak the same dialogues as in the real world, it will give game players more fun and realism. And game players are more and more immersed into the cyber space. However, we observed that only simple and primitive dialogues are used at the market places in most MMORPGS. We introduce personality psychology theory for generating the personality of NPC in MMORPG. And we suggest how to make a conversation between PC (Playable Character) and NPC (Non - Playable Character) according to 'Extroversion - Introversion dimension' and 'Neuroticism dimension'. And we implement the personality dialogue generation program, which is composed of two parts. One is for generating personality, and the other for making dialogue. Personality generator can set a NPC's personality automatically, and Dialogue Maker can control the dialogue styles, quantities, and characteristics of NPC. Thus, the program implemented in this paper can help game designer and scenario writer to make game characters easily. The approach in this paper can be applied to generate various game characters and used to represent agents and avatars of real-time animation.

Texture Mapping is a technique for adding realism to an image in 3D graphics Chip. Bilinear filtering mode of this technique needs accesses of 4 texels to process one pixel. In this paper we analyzed the access pattern of texture, and proposed the high performance texture cache which can access 4 texels simultaneously. We evaluated using simulation results of 3D game(Quake 3, Unreal Tournament 2004). Simulation results show that proposed texture cache has high performance on the case where physical size is less then or equal 8KBytes.

The popularization of VR content is slow. It's because they have not created a new visual experience, that is, 'utility' beyond 'interest'. The utility of VR content starts from functional reality. And to enhanced it, realistic interaction is required. Specifically, this study presents three methods of network play, character artificial intelligence, and Haptic implementation. In order to confirm the hypothesis, we conducted all phases of VR content production from baseball to contents production, play test, and technical verification. Through the test of the user and the evaluation institution about the final product, it was evaluated that it contributed to the realization of the content realism through the realistic visual effect, the play presentation, and the impact evaluation by the vibration.

In recent years, indoor simulated sports have become widely used, and screen baseball system has emerged that can play baseball in indoor space. In this paper, we propose a virtual pitching system that can improve the realism of screen baseball game. This virtual pitching system is characterized in that it uses a transmissive screen in the form of a pitching machine without a pitching hole and installed on the back of the screen. Therefore, unlike existing systems where pitching holes are formed on the screen, it enhances the immersion feeling of displayed images. Also, in this pitching system, the synchronization algorithm between the pitching machine and the virtual pitcher is used to form a sense of unity between the virtual pitcher and the ball according to various types of virtual pitchers, thereby enhancing the reality of baseball games.

To identify the location of the object and improve the realism in 3D game, shadow mapping is widely used to compute the depth values of vertices in view of the light position. Since the depth value of the shadow map is calculated by the world coordinate, the depth values of the static object don't need to be updated. In this paper, (1) in order to improve the rendering speed, using multiple render targets the depth values of static objects stored only once are separated from those of dynamic objects stored each time. And (2) in order to improve the shadow quality in the quarter view 3D game, the position of the light is located close to dynamic objects traveled along the camera each time. The effectiveness of the proposed method is verified by the experiments according to the different static and dynamics object configuration in 3D game.

Recently, increasing numbers of games and simulators are being implemented by employing the physically-based modeling techniques for better realism. In this paper, we propose the implementation techniques for overhead crane simulator based on ODE, the well-known open source dynamic engine. By comparing the dynamic behavior of the proposed system with a commercial engine based simulator, the physical plausibility and the effectiveness of the ODE based OHC simulator are verified. We expect the proposed the OHC simulator can be successfully utilized for virtual training in various educational institutes.

With the recent introduction of HMD devices, there is a growing interest in simulator games that are difficult to experience directly like a FPS, racing game. However, because these gaming require a large volume consol and a additive user manipulating devices for the more reality experience, most of these games are very expensive. Therefore, we propose the Arduino Air Mouse for a sniper simulator game, which maximizes realism and can be enjoyed with small volume and low cost devices. The implemented Arduino Air Mouse uses an acceleration sensor and gyro sensor. Specially, after this device was tested in the a sniper simulator game that is applied the ballistics in the Unity3D environment, the implemented game showed more reality.
