samplePoints()

template<class T >

std::vector< Vec3T< T > > EBGeometry::Random::samplePoints ( size_t  a_count, uint64_t  a_seed  )

inline

Sample a_count uniform random points in the unit cube [0,1]^3.

Deterministic for a given seed: the same a_seed always produces the same points (a std::mt19937_64 seeded with a_seed drives a std::uniform_real_distribution over [0,1)), so callers get reproducible run-to-run results. The engine's output is fixed by the standard, but the distribution's is not, so the points are only guaranteed to match across builds that use the same standard library.

Template Parameters

T	Floating-point precision.

Parameters

[in]	a_count	Number of points to sample.
[in]	a_seed	RNG seed.

Returns

Vector of a_count points, each with components in [0, 1).
