hi
Johannes
 
accoding to your method, i add a sentence "tree.build();" to codes,but i found another question too:
the building tree time is too long , it take 30s to build tree.
 
[...]

      Distance tr_dist;

    // want to compute build time
DWORD   dwStart    =   GetTickCount();
 
  tree.build();  //builds the tree!!!
 
 DWORD   dwEnd    =   GetTickCount();
 DWORD   dwTimeTaken    =   dwEnd   -   dwStart; //this is build time result about 30s    

      Neighbor_search N1( tree, query, K, 0.0, false); // eps=10.0,
nearest=false

     
[...]
 
 
cheers,
thetis
