In this study, a dynamic camera transition system was developed and applied to a cinematic 3D side-scrolling game based on the traditional fairy tale "Jack and the Beanstalk." The game was developed with filmic storytelling and emotionally engaging visual expressions, utilizing zooming, following, panning, and tilting techniques to convey its narrative. The effectiveness of the cinematic presentation in enhancing player immersion was validated through an initial internal review and a subsequent expert evaluation. Therefore, this research aims to assist game developers in creating games that provide high levels of player immersion.

모바일 증강현실 시장은 시장조사업체 카운터포인트리서치가 2021년까지 70조원 규모를 성장을 예측한 것을 비롯하여 많은 자료를 통해 큰 성장을 예고하고 있다. 이러한 증강현실은 현재 더 정교한 증강현실을 위해 디바이스에서 습득한 실제 환경정보를 사용하여 마커 없이도 증강현실을 구현하는 기술을 통해 성장하고있다. 그러므로 성장하는 증강현실시장에 대응하기 위해서는 3D환경을 사용하는 증강현실 기술을 습득할 필요가 있다. 본 논문에서는 탱고기술을 탑재한 기기를 이용하여 3D환경을 습득하고 유니티3D 게임 엔진과 탱고 SDK를 사용하여 카메라 이미지와 3D그래픽이 융합된 자연스러운 증강현실을 구축하는 게임 개발에 대해 설명한다.

In 21 century, Game industry became one field of the cultural content industries. Also, It is one of the most important technologies as a Multimedia, 3-D sound, virtual reality field, and character industry and its scale and effect are getting big. But Korea still lags behind America and Japan in developing game. For that, many support business progressed. However, Special importance〔emphasis〕 is attached to the developing of software engines. In the mean time, The game market of children(under 8) is the biggest one, which form over 30% of all the markets in the PC game market of America. The Children's game, which has both entertaining and educating, is a content-concerned industry. So with a short period of the developing time, they make a high value added. In this paper, 1 study the existing computer games and propose for game contents and the game factor's abstraction suited to the character by kid age. It is concluded that 'Asports', 'Asim,' 'U.J RPG', 'S＋RPG' are beneficial to the child growth on each stage, through serveys analysis of protocol, and research of the cjaracters of the growth on the each age.

최근 유비쿼터스의 활용이 확장되고 있다. 헬스분야에도 예외는 아니다. 기존의 헬스 싸이클은 단지 고정된 싸이클에 현재 자신의 속도와 맥박 등의 일반적인 정보만 제공하기 때문에 장시간이나 장기간의 운동을 하기에는 시간이 지날수록 흥미도가 떨어지고, 자신에 맞는 운동을 하기도 어렵다. 본 논문에서 논의하는 헬스 싸이클은 센서 네트워크와 DB를 접목한 상증 인식 시스템을 이용하여 자신이 현재 상태와 운동 진행 상태를 분석한 맞춤 운동을 할 수 있다. 사용자는 부착된 체온센서와 심전도센서를 통해서 자신의 상태를 실시간으로 확인하게 된다. 센싱된 신호들을 효율적으로 관리하기 위해서 센서네트워크를 형성하여 모든 신호들은 싱크노드에 집중되게 된다. 이 신호들과 DB에 기록된 사용자의 과거 운동기록을 활용하여 현재 운동중인 사용자의 신체적인 상태를 체하게 된다. 이러한 상황인식을 통해서 운동자에게 위험한 요소를 제거하거나 효과적인 운동이 가능하도록 자동으로 제어해주는 것이 이 헬스싸이클의 특징이다. 또한 여기에 충격감지 센서, 유압펌프제어, Python을 이용한 3D 게임엔진을 더하여 운동시에 가상현실적인 상황을 만들고자 하였으며 장시간의 운동에도 흥미가 떨어지지 않도록 하는 것도 상기 헬스싸이클의 특징이다.

Third Person Action Game is a genre receiving continuous interest from many game enthusiasts. The most distinctive feature about third person action games is that the user can actually see the character as well as the various actions, which in turn increases user engagement. Many games are developed using game engines. However, this study designs a third person action game using only DirectX library instead of the specialized techniques in game engines. By doing so, the game development costs will be minimalized. The study also uses several basic algorithms in order to process the various events and to make the animation effects more efficiently managed in the graphic device. The performance superiority is demonstrated by the results of the study.

3D engines loading, and expansion of the usable capacity, next-generation smartphone game markets are rising briskly by the improvement in CPU processing speed of Phones (hardware of smartphone). Therefore, in creating 3D game characters, realistic and free-form animations in a small screen of a smartphone are becoming important. Through this paper, as a method of creating characters and operating for game characters to cause user's feeling, with NURBS data of MAYA, We completed a face in turns of eyes, a nose, and a mouth, and with Polygon Cube tool, modeled hands and feet. After dividing a cube into half and modeling it, through mirror copying We completed the whole body and modeled the low-polygon. Then to model realistic and free-form characters, We completed each detail with ZBrush and applied Divide level up to 4. Though they might look rough and exaggerated, We tried to express stuck-out parts and fallen-in parts effectively and smoothly with Smooth brush effect, map and design the low-polygon 3D characters.

Consumer expectations for drama VFX increased as the influx of overseas dramas increased due to the growth of OTT service, but the current production time of the drama production system has a negative effect on the quality and completion of work. This paper proposes a background rendering using a game engine and a subject rendering using background HDRI as environmental lighting. The proposed workflow is expected to reduce the production time of VFX and improve the quality of VFX. The proposed workflow was verified in 3 steps. Comparing game engine and rendering software according to the same lighting environment and camera distance, comparing rendering with existing rendering method and background HDRI generation, and validating the proposed workflow. For verification, quantitative evaluation was performed using Structual similarity index and histogram. This study is expected to be one of the options to improve the quality of VFX and improve the risk.

3D 그래픽스 환경에서 입체적인 물체가 2D 모니터에 보여지는 과정에는 여러 단계의 공간 변환과 행렬 계산을 거치게 된다. 이러한 공간 변환은 각 단계가 어떤 의미인지 쉽게 이해하기에 어려운 면이 있다. 본 논문에서는 유니티 3D 엔진에서 작동하는 셰이더를 통해 각 단계의 공간을 시각화 하여 학생들이 보다 쉽게 공간 변환을 이해하는 시각화 방법을 제시한다.
