가상환경기술이 여러 분야에서 보편화되고 활용되기 시작하면서 컴퓨터 프로그래밍기술이 없어도 가상환경을 손쉽게 꾸밀 수 있는 저작기술이 필요하게 되었다. 본 논문에서는 가상환경 저작용 시각 언어인 Virtual Environment Specification Language(VESL)를 사용하여 컴퓨터 프로그램 코딩을 하지 않아도 가상환경을 저작할 수 있는 기술을 구현하였다. 우리가 개발한 시각언어 편집기는 VESL을 기반으로 하여 3차원 가상환경을 구축하고 가상환경 내에 정의된 객체들의 물리적 속성을 정의하고 객체들간의 관계 및 유지를 명시함으로써 보다 현실감 있는 동적인 가상 환경을 손쉽게 저작할 수 있도록 하였다.

This paper presents an attempt to develop a visual programming language-based 3D virtual reality authoring tool intended to compose virtual interior space. The rapid development of digital technology and the wide spread of the Intenet have expanded the different uses of virtual reality in a number of applications ranging from interior design to building maintenance. In particular, the construction of cyber spaces based on existing interior spaces is becoming increasingly important. Current research, however, remains at the level of converting 3D models into virtual reality models, despite practitioners' needs for structural space models. Moreover, commercial tools to build virtual reality space have the disadvantage of targeting people who have professional knowledge of computer programs and computer graphics. Accordingly, the 3D virtual reality authoring tool developed in this research - called the VESL system - enables virtual and structural space to be easily composed using intuitive and interactive visual interfaces, which are based on visual programming techniques. The VESL system also provides an XML based semantic description of interior space, to be used to describe interior space information. We anticipate that the virtual reality spaces composed by this system will be of considerable use in the fields of architecture and interior design. Further research issues identified at the end of the research include developing a converter/filter for transforming Internet virtual reality standard language, or VRML, and evaluating the application of the system for practical use.
