Re: [robocup-rescue-s] buildings vicinity

Hi Fahem,
   
  For finding neighbour buildings of each building I have two suggestion the first is simple but not that pricise and the second one more complicated but almost pricise:
   
  1) find all buildings that have CONSTANT distance to it (for example 30000). the problem is that these are not exact neighbours they might be far away from it but it is simple to find.
  2) first you have to find and calculate each building's wall. you can see Friburg fire simulator for it, walls are calculated there. then you need to draw some lines from center of building to each of the building's walls and see if your lines have intersect with other building's wall if so you can have the building that its wall has intersect as neighbour building. (nearest intersections are more correct for finding neighbours).
   
  the second way is time consuming and I suggest you do it in precomputation.

  Hi all,

I want to know how to guess if two buildings are neighbors or not. Is it with
computing the euclidian distance between them. In this case what is the limit
distance. If i can not make a mistake, the map graph known by each RCR agent
do not resolves this problem beacause buildings are modeled as edges and are
not limites by two nodes like roads. So what is the solution?

Thanks for help
