Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

Building a game has been used as effective and attractive way of teaching computer science. Building a usable Multi-player Game is requires important aspects of technology, teamwork and software engineering principles. The whole class was structured in to several teams and students needed to join one or two teams. Each team presented their progress, discussed future milestones and troubleshoots, updated documents for clearer communication and utilized SVN(Subversion) throughout the semester. Unlike usual class setting, all students worked collaboratively together like one company to achieve the goal. In one semester, students started from concept design and completed a working Multiplayer Online Game called "deBugger" (Fall 2009), and "World of Balance" (Fall 2011), while learning game design, 3D graphics, Game Engine, Server-client architecture, Game Protocol, network programming, database, Software Engineering principles, and large application development as a team project.

First of all, What was the modeling technique used to model 3D-Game character? It's a technique developed along several years, by experience... here is the bases Low polygons characters I always work in low polygon for two reasons -You can easily modify a low-poly character, change shapes, make morph for facial expressions etc -You can easily animate a low-poly character When the modeling is finished, Second, In these days, Computer hardware technologies have been bring about that expansion of various 3D digital motion pictured information and development. 3D digital techniques can be used to be diversity in Animation, Virtual-Reality, Movie, Advertisement, Game and so on. Besides, as computing power has been better and higher, the development of 3D Animations and Character are required gradually. In order to satisfy the requirement, Research about how to make 3D Game modeling that represents Character's emotions, sensibilities, is beginning to set its appearance. 3D characters in 3D Games are the core for the communications of emotion and the informations through their facial expression and characteristic motions, Sounds to Users. All concerning about 3D motion and facial expression are getting higher with extension of frequency in use. Therefore, in this study we suggest the effective method of modeling for 3D character and which are based on 2D Graphics.

As a software component for computer game, the physics engine simulates objects' movement according to the laws of physics. This paper introduces a design and implementation of mobile game on the Android platform, where we used JBox2D physics engine library and Android graphics APIs. We borrowed the key idea of this game from Crayon Physics which is known as a famous PC game. This game starts with no way from user character to destination character. The game user has to make a way to destination character from user character by creating polygon objects between them. The user wins when user character meets destination character. However, the game user has to decide the time to create objects and their shapes well because all objects in this game are governed by the laws of physics. As an important thing of this paper, we introduced into this game new input methods of LCD touch and sensors embedded in mobile devices but not in PCs. Game users can create objects by drawing polygons with LCD touch and move objects or characters according to sensor values from accelerator sensors by tilting the mobile device.

Digital simulation which was introduced to the architectural field due to the rapid growth of computer graphics, gave birth to a new type of contents called 'virtual reality', led by the interaction with the users and real time processing. The public attention is drawn to the virtual reality's potential as a next generational space simulation it, having the unique characteristics of 'simulation', 'interactivity', 'tole-presence', and 'immersion', is capable of taking a virtual tour of a space with a size equivalent to that of a real space, as well as proceeding with the design progress. Nonetheless, many problems impeding CPU's real time processing of an excessively loaded architectural model data have been pinpointed over the time. Yet such GPU based game engines as 'DirectX' and 'OpenGL', developed to deal with these impediments, have not been easily applied to the architectural simulation in the design process, due to the high license cost and the specific technical requirements for the system. The virtual reality has been developed and distributed centering around the gaming field, and game developers recently show a greater tendency to include level editors in the package for the expandability purpose. Thus, we plan to propose architecture simulation which utilizes level editors in this study. In addition, the compatibility of the game engine based level editors of Quake and Unreal which form the standards for the open source FPS games, based on VRML, the standard format for the virtual reality, was compared and analyzed. Taking the example of Villa Savoye of Le Corbusier, its application possibility as an architecture simulation was assessed, by measuring the extent to which the performance of such characteristic features of the virtual reality as interactivity, immersion, and tele-presence, was improved.

Recently, Our average life span of korean people is extended and fast-growing an elderly population caused by Being Improved our living conditions and medical science level. Our another problems which being faced by an aging population are that marked psychological and social changes of the aged. The psychological changes of the aged is related to how they make their living and it strong influences on their successful aging process. For health of the aged, there is an urgent need of recreation which can be social activities to void decline their own process of thinking and the executive ability to adapt for controlling health. Therefore, thepurpose of this recreation Courseware program is to help the alienated minorities to achieve the optimal health and best quality of life based on the knowledge of the social-activities and to understand the korean traditional culture plays. Finally, This study could contribute it as a baseline model for the empirical study and to develop further recreation program for the elderly social activities and sufficient for needs of understanding our traditional culture plays.

This paper proposes an efficient method for design and implementation of the artificial intelligence (AI) of 'omok' game on the GPU. The proposed AI is designed on a cooperative structure using min-max game tree and genetic algorithm. Since the evaluation function needs intensive computation but is independently performed on a lot of candidates in the solution space, it is computed on the GPU in a massive parallel way. The implementation on NVIDIA CUDA and the experimental results show that it outperforms significantly over the CPU, in which parallel game tree and genetic algorithm on the GPU runs more than 400 times and 300 times faster than on the CPU. In the proposed cooperative AI, selective search using genetic algorithm is performed subsequently after the full search using game tree to search the solution space more efficiently as well as to avoid the thread overflow. Experimental results show that the proposed algorithm enhances the AI significantly and makes it run within the time limit given by the game's rule.

Hand tracking is currently one of the most promising technologies in XR with the release of extended reality (XR) devices, in which hand tracking is used as the main manipulation. Hand tracking offers advantages in terms of immersion and realism, and as a result, it is being employed in a range of fields, including education, business, and medical care. The archery movement requires using both hands at the same time, but requires sophistication to hit the target and is a movement that has cultural and sports significance in the past. This study aimed to implement this archery movement. Therefore, this paper used the XR Hands package provided by Unity to recognize hand movements, explored the underlying OpenXR, and finally implemented the archery movement and tested it in Meta Quest 2.
