Paper Abstract

Nowadays, urban system has increasingly become more complex in spatial context with impressive distributed features. Urban design highlights the challenge encountered in delivering context sensitive solutions in aspects of planning and development process in dense environment. Since traditional techniques in Geographic Information System only allow participants to scheme with sketches, such three-dimensional or even four-dimensional urban space would be rarely improved on the two-dimensional medium. The high-resolution three-dimensional city models have been emerged from a growing awareness focused on strategic plans. This paper aims at bringing discussion into the development of algorithmic research and applications of three-dimensional city models in three aspects: (i) techniques and features in urban Geographic Information System are briefly outlined; (ii) an effective framework on the research and applications of three-dimensional city models is systematically introduced; (iii) advices to benefiting urban planning based on three-dimensional dynamic virtual environment are definitely stated. In a word, the potential will make efforts in urban design with photorealistic representation of urban area significantly.
