Detailed Description

Namespace for random sampling utilities (a single, centralized home for RNG use).

Function Documentation

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.

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).
