| Title of the Talk: |
A TECHNIQUE OF ABSTRACTION AND BUILDING REPRESENTATION
IN VIRTUAL URBAN MODELS
|

| Abstract: |
This talk presents a technique for creating abstract representations of modern urban areas. We identify and apply cartographic
and cognitive principles to develop a solution that is implemented in the context of a state of art Geographic Information Systems. At the core of our solution is a building facade modeling approach that supports varying degrees of abstraction. This is achieved by introducing a concept of "facade waveforms" and representing building facades as combinations of these waveforms. A Fourier series approximation of the waveforms is used during the rendering processes resulting in an elegant solution to anti-aliasing. The formulation retains the semantic information in the representation that enables meaningful extensions like night time facade generation. The solution is implemented as a pixel shader and therefore leads to a large reduction in texture memory requirement compared to existing building rendering techniques. Additionally, in the case of web based systems there is significant reduction in bandwidth requirement. We highlight the features of the proposed solution with demonstrative images.
