Hi,
I have a data set of several hundred thousand points. Each point is saved as a three dimensional coordinate, i.e. (x,
y,z). What I'd like to do is given a point in that space, get a list of all of the points in the table within some
radius.
I'm familiar with the q3c package that does this for points that lie on a sphere, but is there something comparable for
radialsearches on 3D cartesian points? Speed is definitely an issue given the number of points I have.
Thanks for any suggestions!
Cheers,
Demitri
