2D 게임의 이미지들은 2D 스프라이트(Sprite) 조각들을 같은 평면에 겹쳐 그리는 방식으로 표현한다. 탑다운 뷰(Top-Down View) 2D 게임 시점은 평면의 그림에 입체적인 묘사를 함으로써 캐릭터나 오브젝트가 수직으로 일어서 있는듯한 3D 느낌을 전달한다. 그러나 실제로는 2D 평면이므로 3D 그림자 맵(Shadow Map) 방식을 사용할 수 없는 단점이 있다. 본 논문에서는 2D 스프라이트 오브젝트의 그림자를 3D 그림자맵으로 생성하는 방법과 동반되는 이슈들을 제시한다.

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.

The portable game market is growing so fast recently. However, the development activities of domestic game development companies have been very week, which is mainly due to the lack of efficient and economical game development library This papers deals with how to implement 2D game library for SONY PSP game console that is very popular thesedays as a portable game console. We have ported the open source SDL library to PSP. Consequently, developers could develop games in PC environment and port it to PSP very easly based on the game library.

한국전자통신연구원(ETRI) 3D 게임엔진 '드림3D'의 기술 이전료가 인하됐다. ETRI는 3D 게임엔진 '드림3D'의 기술 이전료를 당초 계약금 6000만원에 러닝로열티 2%를 받기로 했던 방침을 수정, 계약금 4000만원에 러닝로열티 1%로 하향 조정했다. ETRI는 이를 위해 기술이전 후 '드림3D' 개발진에 피드백을 전달, 3D 게임엔진 개선에 공헌할 것을 기술 이전료 인하조건으로 제시했다. '드림3D'는 정부가 세계적인 게임엔진을 개발, 저렴한 가격에 국내 업체에 공급함으로써 국내 게임개발 환경을 한 단계 끌어올린다는 목표 아래 ETRI 과제수행업체로 선정, 2년 만에 개발 완료한 '3D온라인 게임엔진'이다

Casual games are easy in terms of control and mode, and thus everyone can enjoy them in their free time. Character games, in particular, feature a variety of cute and attractive characters. Such character games are now available for smartphones, which are used by a large number of users, as well as for PCs. This paper is aimed at demonstrating the design of 2D side-scrolling casual shooting games utilizing Unity 3D Engine, which can be manipulated on smartphones. Unity 3D engine was used because it supports multi-platform with low costs, and it makes it possibile for games to be operated on various platforms using a single program source code. This approach is unique because the design of the games uses cute characters, attractive concepts and easy control, targeting users in their 10s or 20s, unlike existing shooting games that are serious.

Today due to the development of technology, 3D graphics have become an essential element of the game graphic. When game companies create a game using 3D graphics, game users can enjoy a better game graphics like photo-realistic live action than 2D game graphics. And because the game companies have many advantages in creating games which are easy to deal with many basic effects and special effects, in video game business field, 3D game have become the mainstream. This paper will inquire the characteristics of 2D spline which is basic to various kinds of 3D modeling necessary to making 3D game graphics, compare and analyze the merits and demerits of each kind of spline and find out its development history.

Domestic game companies are competitive in developing on-line 2D game contents. However, they have difficulties in maintaining the competitive edge in the area of on-line 3D game technologies owing to the limited funds and technologies. The 3D on-line game engine technologies we have intended to propose in this research are highly expected to be the key technologies ensuring the competitive edge over other countries. For this, we propose a full 3D online game engine that reflects the cutting edge technologies trend in the computer gaming industry. Our game engine is integrated with rendering and animation core technologies to visualize the game world, and provides stable network service through the Internet using server technologies.
