Constructing 3D Models and Virtual Reality Contents of CheongGyeCheon

청계천의 3차원모델 및 가상현실컨텐츠 제작

With the development of Geospatial Technology (GT), many countries and industries have been expanding their investment in constructing a cyber territory. As the critical components of this cyber territory, three-dimensional models and virtual reality contents based on these models of urban areas in particular have been considered. These models and contents can be intensively used for a city to decide the policies efficiently and to attract the interests of peoples while planning and performing large projects. In this study, we have thus constructed the 3D models and virtual reality contents of the large areas along the CheongGye stream to visualize the environment of these areas before and after the CheongGyeCheon restoration project being completed. Furthermore, we propose efficient methods to construct and visualize these large models, such as tile mapping and multiple LOD application.
