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 special 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.
