Summary: TetrahedronSampler: Sample uniformly from a tetrahedron
Key: RNG-135
URL: https://issues.apache.org/jira/browse/RNG-135
Project: Commons RNG
Issue Type: New Feature
Components: sampling
Affects Versions: 1.4
Reporter: Alex Herbert
Assignee: Alex Herbert
Create a sampler to sample uniformly within a
[tetrahedron|https://en.wikipedia.org/wiki/Tetrahedron].
{code:java}
public abstract class TetrahedronSampler implements
SharedStateSampler<TetrahedronSampler> {
public static TetrahedronSampler of(double[] a,
double[] b,
double[] c,
double[] d,
UniformRandomProvider rng);
}
{code}
Inputs {{a,b,c,d}} are the vertices.
Sampling can be performed using the algorithm of:
