SPHERETRI is a set of high-performance vectorized MATLAB functions for building a triangulation of a unit sphere based on recursive partitioning of each of Icosahedron faces. The resulting triangulation vertices form a nearly even grid on a surface of a sphere.

Example #1 (100k points):
>> nPoints=100000;
>> tic;[vMat,fMat]=spheretri(nPoints);toc;
Elapsed time is 0.103696 seconds.
>> size(vMat)

ans =

163842 3

Example #2 (1 million points):
>> nPoints=1000000;
>> tic;[vMat,fMat]=spheretri(nPoints);toc;
Elapsed time is 1.988475 seconds.
>> size(vMat)

ans =
