Due to the expiration of the 3D printer's patent, the articles covering the market activation and bright prospects for the future industry are being released. What are the requirements for the 3D printer to become popular like a general printer? To get the answer, on-line survey was performed for the activation of 3D printer. As a result, tit is observed that he public prefers creative printer and figure, and prefers to use through pay or free download rather than designing digital blueprint, which is output data. For the activation and popularization of 3D printer, figure is familiar to the public who are frequently exposed to image media contents, and it also has motivation factor to use and purchase 3D printer. For distribution of digital blueprint of figure content, the preparation of related law and regulation and activation of online market would be of help for activation of 3D printer.

Due to the spread of COVID-19, many local governments are burdened with the influx of large-scale tourists. As a climate that values Work-Life-Balance has emerged, interest in individual life and satisfaction is rapidly increasing. In addition, due to the popularity of the metaverse field, many people are increasingly interested in related content. In particular, "Animal Crossing: New Horizons" sold more than 15 million copies in 2020, and is enjoying exchanges of interior design, fishing, and collecting insects here. In line with this trend, this study introduces the development of online fishing games based on Jeju infrastructure. This paper focuses on implementation and development, and in particular, it introduces differentiated games through character animation optimized for developing a topographic model that maximizes the beauty of Jeju Island's topography based on the Unity 3D engine.

최근 컴퓨터 게임은 3D 가속기를 이용한 3D 실시간 렌더링을 게임에서 제공하여 보다 사실적으로 묘사된 그래픽 환경 하에서 게임을 즐길 수 있게 되었다. 또한 네트워크 인프라가 구축됨에 따라서 네트워크를 이용한 온라인 형태의 게임들이 개발되고 있다. 이러한 온라인 게임은 스탠드 어론 형태의 게임과 달리 네트워크를 이용하여 가상의 공간에서 원격지의 다른 사람들과 같이 게임을 즐기는 형태로서 여기서 발생되는 게임적 재미요소는 그 전의 어떤 게임에서도 찾아 볼 수 없는 즐거움을 준다. 이러한 이유로 현재 많은 게임들이 3D 그래픽과 온라인을 접목시키고 있다. 이에 본 논문에서는 현재 개발 중에 있는 3D 온라인 슈팅 게임'을 기준으로 개발에 필요한 엔진 기술과 이를 이용한 개발 방법론을 제시하고 현재까지의 개발 과정에서의 문제점과 이에 대한 보완 대책을 제시하고자 한다.

This paper introduces the research and development of automatic generation technology to develop the character agent. The R&D of this technology includes three major elements-body model generation, automatic motion generation and synthetic human generation. Main areas of application would by cyber space- 3D game, animation, virtual shopping, on line chatting, virtual education system, simulation and security system.

In this paper, we present the architecture of graphics processor and its instruction format for the mobile device. In addition, we introduce tile shader data structure for the on/off-line compilation based on the OpenGL ES 2.0 and a new optimization method based on the ILP(Instruction-Level Parallelism). This paper shows where a processor with the sane core clock is being used, the shader instruction resulted from the compile structure and method in this paper is approximately 1.5 to 2 times faster than a code based on the single instruction.

Today the lectures are usually practiced in a teacher-led traditional classroom system or a student-led e-learning system. Students passively follow the teacher's lectures in both systems, though. Also due to the advances in 3D Computer Graphics and Game technologies, there are trials to exploit the positive effect of games in learning. The serious games, specifically designed games for an educational goal, or existing games for a special class have been used as lectures. Still these games have a great difficulty in being integrated into the educational system technically and economically. Therefore a new 3D MMORPG based lecturing system is presented in this paper. In our new lecturing system, the characteristics of a 3D MMORPG, achievement, sociality, and immersion, are provided to motivate students to participate actively in a lecture. A teacher and students interact with each other in realtime as 3D characters in a 3D virtual classroom on-line. An ordinary teacher can also easily apply our new system to existing classes since a teacher only needs to specify a slide file to prepare a lecture. For the future work, a user study and the effect of our new lecturing system will be performed.

In the great motive power which promotes the Game of future to develop. three main factors focus on 3D Graphics, Network and Virtual Reality. the Network technique as necessary elemental technique in Next-generation on-line game is being researched largely. However, from viewing the features of on-line game, if many users meet in same server, it not only causes heavy load to the server and brings inconvenience to the users, but also increases expense to the service provider and creates a problem which is to put up server or not. A proposal is going to do hybrid distributed system a client hardly depends on server for this paper, and to be able to enjoy a network game through information alternating current between clients. depended on the existing server, and the most message processing did a design in order to achieve between clients. A design way to propose is as follows. Primarily it was done in order proposed a message grade anger process way, and to be able to manage server or a client according to importance of message, and, with the second, did a Client-Server method and a Pear-to-Pear method at the same time, and a chase did efficiency. Third is going to propose other problem solving way by message grade anger in multi-anger and a security section of a message cue.

This paper measures and compares the traffic of a series of Massively Multiplayer On-line Role Playing Games(MMORPG). The target games are 'Lineage' and 'Lineage II' developed by NCsoft, which are ones of the world's largest MMORPGs in terms of the number of concurrent users. We collected about 1 tera bytes of packets of 'Lineage II' for four days including a weekend. These packets are analyzed and compared with those of 'Lineage.' Packet size, packet inter-arrival time, and bandwidth usage are compared. The traffic of the two games shows much difference because original 'Lineage' is a kind of 2-D based MMORPG, while 'Lineage II' is 3-D based. By comparing the characteristics of the traffic of these games, we can anticipate future needs of network and game structure.

If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.

This study analyzed the importance of user activity, communication between users and identity establishment by growth and change of player's character through users' communication structure and then it classified such an importance into activity by group, dealings, information sharing, duel and strategy performance. It also looked into the plans to revitalize smooth social relationship and suggested for users to behave with responsibility in virtual society. In the virtual space where thousands of people connect and interact with each other every day, users find out their identities through human relationship with others proceeding solo story. What is more important is that users consider virtual space as a society and feel collective responsibility on words and behavior against others.
