You would need to do that by hand; note that there is a function to convert
from coordinates to graph vertices.

Hi Jeremiah,
You mean there is something more "built in" than this: ?
#include "boost/graph/adjacency_list.hpp"
#include "boost/graph/simple_point.hpp"
namespace boost {
enum vertex_coordinate_t { vertex_coordinate };
BOOST_INSTALL_PROPERTY(vertex, coordinate);
};
int main(int argc, char *argv[])
{
typedef boost::simple_point<float> PointType;
typedef boost::adjacency_list
> Graph;
Graph g;
typedef typename boost::property_map::type CoordinatePropertyMap;
CoordinatePropertyMap coordinatePropertyMap =
get(boost::vertex_coordinate, g);
return 0;
}
(i.e. can you point me to the function you are talking about : ) ?)
Also, the reason I am not using boost::grid_graph is that there are
"holes" in my graph - i.e. not every integer coordinate has a vertex.
Does the coordinate-to-vertex_descriptor function you are talking
about handle the case when a vertex doesn't exist at the specified
coordinate?
Thanks,
David
