Parametrized uniform triangulation of 3D circle/sphere

Short function for parametric triangulation of 3d sphere

Function sphereTriangulation discretize a sphere parametrized with:
- radius R and,
- number of division.

Triangles are formed by spiting unit octahedron triangles, so nice mesh is retrieved. My usage was for FEM analysis - results are stored so that they could be used for saving in STL and further meshing.

Code is short and commented, if You have any question You can post.
