The potential of virtual reality modeling language [VRML] with digital photogrammetric modeling for virtual environments

Abstract

In this preliminary study, we have investigated the functions of VRML in the representation and communication of visualization from various viewpoints, the evaluation of planning information and a simulation model. As a 3d modeling prototype, experimental Web site was set up and used to disseminate design data as VRML models and HTML text to the designers, and participate people. On this issue, we discuss the way our design information documents were developed in VRML, the issues we faced implementing it, and critical feedback from the users of the Web space/ site. We analyze the usefulness of VRML as a communication tool for the designer and users. At the meantime, we discuss urban design faces as it shifts to embrace widespread use of visualization communications infrastructure for design process. On the other hand, the paper will consider the potential of non-conventional photogrammetry in computer modeling and virtual reality technologies being developed on the World Wide Web (WWW) for the visualization, observation, modeling and analysis of virtual environment. This project addresses the whole range of issues that arise from the digital image-based modeling on the VRML, which represents the physical environment. The aim of the research is to process the image data acquisition, modeling on the computer and representation on the Internet. This research tests new computer programs oriented to constructing 3D models and graphics through image-based calibration modeling. The paper also will consider the application of these techno logies in a range of contexts: such as environmental design, design process participation, education and training.
