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 into 4 triangles with vertices in the middles of original face edgeMidMat. spheretri function takes a number of requested points as an input. An exact number of points in the returned triangulation may not match this number, the function will choose a depth of Icosahedron partitioning minimally sufficient to provide the requested number of points. Alternatively you can use spheretribydepth function that expects a partitioning depth as an input.

Examples:

[vMat, fMat] = spheretri(500);
patch('Vertices',vMat,'Faces',fMat,'FaceColor','g','EdgeColor','k');

[vMat, fMat] = spheretribydepth(3);
patch('Vertices',vMat,'Faces',fMat,'FaceColor','g','EdgeColor','k');
