GridSphere (Scripts) Publisher's description
The grid may have a total of exactly 12
The grid may have a total of exactly 12, 42, 162, 642, ... points. Mathematically speaking, the grid may have either 12 or 2 + ( 10 * (4 ^ k) ) points, where k is a positive integer. The user may request any number of points, and the closest attainable value will be produced. All code is compatible with GNU Octave. The algorithm was developed by Nick A. Teanby of Oxford University. Refer to his website for the publication describing the approach and more elaborate geodesic grid software written in IDL: http://www.atm.ox.ac.uk/user/teanby/software.html#icos. Use the FindNearestNeighbors function, available on the MATLAB file exchange at http://www.mathworks.com/matlabcentral/fil...hbors-on-sphere, to find the grid points closest to arbitrary query points.
GridSphere and FindNearestNeighbors share some functions in common. Each package contains a copy of these functions so that both can stand alone. To eliminate duplicates, simply move all the files into a single folder and replace the shared files when prompted.
