This study proposes a method for acquiring and managing basic information on building, which is continuously updated through construction and re-construction, in order to implement 3D-GIS based on geometric shape information and building information. First of all, distinctions between BIM and GIS information models are described, and then an overview of CityGML for virtual city and its Level of Detail are introduced. At last, a prototype for extracting building geometry from BIM data in accordance with CityGML is presented for demonstration. By using IFC data from BIM, this approach enables a lot of firms and contractors in building industry to utilize their 2D/3D, data on sites and buildings, and also to save many effects for generating exterior and interior building models which are inevitable for implementing National GIS.

The purpose of this study was to investigate the effects of visual properties on the human movement behavior experimentally and empirically using spatial analysis technique based on ecological perception theory. For the survey of choosing behaviors of heading direction in built environments, the experiment was conducted in which the subjects were made to choose moving directions in some spaces using the virtual environment simulation tool, and then comparative analysis was conducted on the interrelation between the experiment results and various visual properties in existing spatial analysis techniques based on ecological perception theory. As a result, the occlusivity of the isovist theory was found to be the most significant index in the human choice of heading direction, and the longest radial also showed somewhat significant effect on it.

In this paper, we propose virtual building construction plans. For this, we compose the construction materials with components and assemble components in pattern. When we change assembled constructions, we can design the building efficiently with patterns if the parts are selected. Also through information analysis of material components or patterns, we can provide information which is necessary to a reconstruction to the designer. Using steal house method, the assembly functions were comprised of a wall, a room, a window, a door, roof etc. Also We explained the materials automatic extraction method which applies steal house.

The vehicle simulation (flight simulator) in 1920's was the first in the virtual reality. With the development of precise optical and electromagnetic equipment, the virtual reality widened its application for other purposes than military one. Based on the realistic display technology, it is more and more common in the various areas such as entertainment, medical profession, learning, film, architectural design, tourism and etc. In 1989, Jaron Ranier was the first to use the terminology 'Virtual Reality'. With this term, all virtual projects could be classified in a single item. But even before the term was used, the virtual reality has been studied up to now. As a part of virtual reality, the human thirst for the impossible thing has led to the development of ride film. The ride film consists of the special technical elements as well as the psychological analysis of human being. The ultimate purpose of virtual reality is engrossment through interaction. Even though the real interaction requires interface, input sensor and reaction ability, the ride film is not an element of the typical interaction. The virtual reality is mostly defined in technical terms now. But in this study, we will analyze the concepts worked out by Professor Michael Haim who is called a philosopher in the cyberspace in aspect of experience-oriented definition. We will analyze the adaptability of virtual reality based on his concepts such as artificial reality/ interaction/ engrossment/ networked world/ remote display/ simulation/ onmon engrossment. And also, we aim to suggest the directions of developing the ride films for perfect engrossment and to draw optimized conclusion thereon. In this viewpoint, we consider that the study of ride film on which there were few case studies will contribute to level up the basic frameworks of IT technology and the digital image.

Information and Communications Technologies(ICT) represented by Multimedia, Virtual Reality and Network could be used as the better ways to preserve and restore the original shape of cultural contents. This paper presents the detailed methods of Multimedia and Virtual Reality technologies to digitally implement the traditional wooden buildings which are called as a typical 'Korean Cultural Content." We implemented a 3D modeling of architectural parts, realized a roof curve, and texture-mapped the material qualities of traditional wooden buildings by using Graphic techniques. In addition, the information, which is implemented by marker-based Augment Reality, for the traditional wooden buildings can be obtained through the mobile appliances such as a smart phone. We, also, presented how to practically use the implemented digital Korea traditional wooden buildings.

Virtual reality is actively applied in the fields of games, entertainment, communication, sports, and architecture. In particular, many virtual reality-based education systems are being developed in the field of education, creating efficient learning effects. In addition, virtual reality-based education is used in areas such as maintenance, fighter control, medical care, and firefighting as it can maximize the educational effect through the mastery process of the function itself through the curriculum as well as indirect experiences of dangerous situations that are difficult to experience. However, due to technical limitations, lack of contents, and lack of theoretical research, the level of application of military education and training is still insufficient. This paper aim to contribute to the development of a virtual reality-based education system as a military training system by developing a high-quality drop training system applicable to military group descent training, studying key technologies and implementation methods necessary for development.

컴퓨터의 발전으로 이를 이용해 제품을 디자인하는 CAI가 발전하게 되었다. 산업 디자이너들은 CAID 도구를 사용하여 3차원 장면을 시각화하기 위하여 이를 2차원 이미지로 만드는 렌더링 기능을 수행한다. 렌더링 기능은 디자이너들이 자신이 디자인 제품의 재질, 조명, 카메라 등을 시뮬레이션 해 볼 수 있게 하여 중요한 기능으로 활용되고 있다. 하지만 현재의 컴퓨터 입출력 시스템을 활용하여 CAID 도구의 광원과 카메라 등의 3차원 위치와 속성을 조작하는 데에 인터페이스 상의 문제가 발생한다. 본 논문에서는 증강현실과 실체적 인터페이스를 활용한 가상의 라이트 조작 공간인 TLS(Tangible Lighting Studio)를 제안한다. 이는 광원과 카메라의 위치, 효과를 물리적으로 조작할 수 있는 유닛들로 구성되어있다. 그리고 가상의 모델을 실제와 같이 보이게 하기 위한 입체 디스플레이 방식을 제안한다. 새로운 실체적 인터페이스를 제안함으로써 산업디자인 분야뿐 아니라 건축, 원화, 사진 촬영 등의 분야에서 시뮬레이션 도구로 적용할 수 있으리라 기대된다.

Recently, the advent of World-Wide-Web(WWW) and the explosive popularity of the Internet gave birth to collaborative applications which were enabled by computers and networks as their primary media. And the progress of 3D computer graphics enabled collaborative application with 3D virtual environments or distributed virtual environments. In this paper, we explain our implementation of Share collaboration engine and Virtual Architectural Engineering 2000 (VAE2000) system which is our pilot application implemented with Share collaboration engine. And we explain problems presented by our experiments with VAE2000 system. For those problems, we design our new middle-ware system, SHINE(SHared INternet Environment). The SHINE proposes new concepts and approaches for collaboration with 3D objects in a virtual world.
