SampleSphere()

static bool SampleSphere ( unsigned  N, std::vector< CCVector3 > &  dirs  )

static

Sample points on the unit sphere.

Transcripted from MATLAB's script "partsphere.m" by Paul Leopardi, 2003-10-13, for UNSW School of Mathematics.

As points are sampled on the unit sphere, they can also be considered as directions. WARNING: returned array is on the user responsibilty!

Parameters

	N	number of desired sampled directions
[out]	dirs	set of N points

Returns
