29 Jul 2009 FAST K-NEAREST NEIGHBOURS SEARCH 3D VERSION The 3d version of GLTREE Author: Luigi Giaccari

Hi again,

i have found the erroneous line in KNNSearch.cpp:

instead of
                    pk.x=qp[i];pk.y=qp[i+N];pk.z=qp[i+N+N];
one has to use
                    pk.x=qp[i];pk.y=qp[i+Nq];pk.z=qp[i+Nq+Nq];

Now it's perfectly running. Very well done.

Best regards,
Johannes

Hi Luigi,

i really appreciate your tough work already for the 2d version.

However, there is some bug in your code that results in wrong results whenever the number of query points q does not match the number of data points p. If one adds a number of zeros to make the point numbers match, the code runs correct.

Are you able to fix this?

Best regards,
Johannes

07 Jul 2009 export_fig Exports figures nicely to a number of vector & bitmap formats. Author: Oliver Woodford

Really nice.
I still have a problem using uipanels (guis):

 If i create a plot and a colorbar, the colorbar will not be printed in the result.

Is it possible to enable for a search for colorbars? I tried to adopt your code but failed in copying the correct stuctures.

To say it with Stefan: Can you fix/enable that?

Really good. Nice. Fast. With C support. Great.
20 Mar 2009 FAST K-NEAREST NEIGHBORS SEARCH Simple but very fast algorithm for nearest neighbors search. Supports KNN and radius search. Author: Luigi Giaccari

Really good! Great work and just came in handy.
Thanks a lot for sharing your work!
