다중환경에서의 Open Graphic API를 이용한 3차원 공간정보 시스템 설계 및 구현

다국어 초록 (Multilingual Abstract)

3D mobile GIS application is at the beginning development stage in the GIS domain, compared to other GIS application using handheld devices on wireless communications and various sensor systems.
In this study, an integrated 3D authoring and rendering system, based on object-oriented approach, running on handheld devices was proposed, designed and implemented for the graphic pipeline processing in this system. OpenGL(Open Graphic Library)and OpenGL

ES(Embedded System) is used for stand-alone platform and mobile platform, respectively. In these systems, 3D objects such as terrain, building, road and user-defined geometric ones can be modeled and integrated for augmented 3D landscape scene generation. In both systems, 3D urban landscape features authoring system by geo-based spatial feature database schema definition is composed of several functions: modeling, editing and manipulating of. 3D landscape objects, generating of geometrically complex type features, and supporting of both database and file system with manipulating of attributes for 3D objects. As well, for realistic scene rendering, texture mapping of complex types of 3D objects with image library is also possible. In developing on the mobile system, main graphical user interface and core components were implemented under EVC 4.0 MFC and tested at PDA as iPack H4100 and LG-DMBPM80 device with Pocket PC. It is expected that dual interfaced 3D geo-spatial information systems supporting registration, modeling, and rendering systems for can be effectively utilized to 3D urban environments analysis, 3D simulation and 3D navigation related to further 3D mobile mapping.
