Create a tetrahedron sampler with vertices
a, b, c and d. |
double[] |
sample()
Create an object sample.
|
TetrahedronSampler |
withUniformRandomProvider(UniformRandomProvider rng)
Create a new instance of the sampler with the same underlying state using the given
uniform random provider as the source of randomness.

Sampled points are uniformly distributed within the tetrahedron.
No test for a volume is performed. If the vertices are coplanar the sampling distribution is undefined.
