The informatization of Korea is accompanied by the great growth of new strategic export industry, as of mobile phone or semiconductor LCD. Speaking to the situation of mobile phone, Motorola swept over the American domestic market in the beginning of 1990s, digital mobile communication as CDMA developed swiftly in Korea. In 1996, the first year's CDMA users of Samsung were merely one million, nevertheless, the world's sales in the first half of this year is up to 92 million. In this p aper I design 3D application based on J2ME and implement a freely removable 3D object which happened in a 3D scen e by receiving the keyboard response of mobile device with WTK (Wireless ToolKit) simulator. It contains benefits of improvement of relative speed and high-level functionality such as scene graph, keyframe animation, etc.

While many games have been published that are used with input-devices such as a mouse and keyboard, the number of games that can recognize the behavior of a human utilizing devices such as Kinect and Wii has increased. In this paper, we present the development of a baseball game that utilizes a Leap Motion Controller. A Leap Motion Controller recognizes accurately the movement of a user's fingers. Our implemented game consists of characters, a background and animation. It is a moving animated game in which the users play a game in point of view of a third person. The major feature of our game is that the game players can enjoy the game using a Leap Motion Controller.

With the rapid development of 3D animation, MetaHuman is widely used in film production, game development and VR production as a virtual human creation platform.In the animation production of virtual humans, motion capture is usually used.Since different motion capture solutions use different skeletons for motion recording, when the skeleton level of recorded animation data is different from that of MetaHuman, the animation data recorded by motion capture cannot be directly used on MetaHuman. This requires Reorient the skeletons of both.This study explores an efficient skeleton reorientation method that can maintain the accuracy of animation data by reducing the number of bone chains.In the experiment, three skeleton structures, Rokoko, Mixamo and Xsens were used for efficient redirection experiments, to compare and analyze the adaptability of different skeleton structures to the MetaHuman skeleton, and to explore which skeleton structure has the highest compatibility with the MetaHuman skeleton.This research provides an efficient skeleton reorientation idea for the production team of 3D animated video content, which can significantly reduce time costs and improve work efficiency.

Nowadays, 3-D(Three-dimensions) is used in various field such as Games, Movies, Animations etc. Especially the Role of 3-D computer graphic is being generalized by turnover of Screen from '2-dimensional' to '3-dimensional'. There are not enough data about 'Motion Capture' even though it plays main function in 3-dimensional movement. 'Motion Capture' could be also unfamiliar for people. And as a matter of fact, the use of this equipment is limited due to its high cost. Therefore, I studied the outline of Digital Motion Capture system and its application to 3-D game Character Animation. And I checked the movement of 3-D Character after transplanting the Motion Data to the 3-D Character. I acquired Motion Data by Optical Motion Capture Equipment which we possess and transplanted it into the 3-D Character then Implemented it as walking, running and hitting which are the basic motions of Expression.

In this paper, we present a practical method for generating facial animation by using an optical motion capture system. In our setup, we assumed a situation of capturing the body motion and the facial expression simultaneously, which degrades the quality of the captured marker data. To overcome this problem, we provide an integrated framework based on the local coordinate system of each marker for labeling the marker data, hole-filling and removing noises. We justify the method by applying it to generate a short animated film.

World Skills Korea Committee for Industrial Policy in the 21st century to meet the needs of the historical profession in animation filed excellent acquisition and the need for human resources through research and public hearings beginning in 2009 a new animation filed in the National Skills Competition adopted the profession. Youth animator's features, technologies, and creativity to develop features that help the tournament by forming social relationships and participation. In this study, four years of the test questions analysis and making questions on animation field the way the game athletes and coaching staff interviews, surveys of major in animation through a detailed analysis of the challenges and constructive suggestions by the direction of the best animated field, excavation and occupations were aimed at improving levels of functionality.

In our society, the current smart devices have been commercialized and more time than most people are in contact with smart devices than the time in contact with the PC, it shows the same trend in terms of the game industry. Thus in the study, it was to try to make a game by utilizing the characteristics of only the smart devices in mobile environments among them by using the gyro sensor implementing the movements of characters. In particular, undergraduate student made various attempts to implement a single game using the sensor used in smart devices. In this paper, we have planned the adventure 3D running game that allows users to easily fun to play. Our goal is to implement one stage. We have discussed that you have designed and implemented.

The importance of a using the visual media in English education has been increased. By an importance of Characters in English language content, the more effort is needed for a learner to show the English pronunciation and a realistic implementation. In this paper, we tried to review the Syntax-based Educational Contents Authoring System. For the more realistic lip-sync character, 3D character to enhance the efficiency of the education was constructed. We used a chart of the association structure analysis of mouth's shape. we produced an optimized 3D character through a process of a concept, a modeling, a mapping and an animating design. For more effective educational content for 3D character creation, the next research will be continuously a 3d Character added to a hand motion and body motion in order to show an effective communication example.

실시간 3D 렌더링 게임의 제작 환경에서 캐릭터의 움직임은 모션 캡처(motion capture)를 통해 만들거나 애니메이터에 의해 제작된다. 걷기나 달리기 등 일정한 속도로 캐릭터가 움직이는 모션은 캐릭터가 제자리(in place)에서 움직이도록 한 뒤에 게임에서 프로그램에 의해 일정한 속도로 움직임으로써 구현할 수 있다. 하지만 일정하지 않은 속도로 움직이는 모션을 같은 방식으로 적용하면 캐릭터의 이동이 어색해진다. 이런 어색함을 보완하기 위해 언리얼이나 유니티 3D 등의 엔진에서는 루트 모션(root motion) 기능을 사용하고 있다. 그런데 루트 모션을 위한 계층 구조는 애니메이터의 작업 효율을 위한 계층 구조와 다른 측면이 있다. 본 논문에서는 3ds Max를 사용하여 애니메이터 친화적이고 루트 모션에도 적합한 캐릭터 리깅을 제시한다.

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.
