In this case the buildings are randomly dispersed within a pre-defined 
object. Writing away the geometric data would be possible, without 
knowing what the final union of buildings would look like however.

The block object defining the contours of the building union can be 
drawn according to an image_map of street patterns on the underlying 
height_field.
