Paper Abstract:
|
A data structure based on urban blocks which vastly improves rendering speed in urban walkthroughs and flights is
presented in this paper. The city is split by means of a quadtree partition and the block is adopted as the basic urban unit.
One advantage of blocks is that they can be easily identified in any urban environment, regardless of the origins and
structure of the entry data. Results are promising and lead to a factor three increase in rendering speed. |
