chrono::utils::PDSampler< T > Class Template Reference
Description
template<typename T = double>
class chrono::utils::PDSampler< T >
Sampler for 3D domains (box, sphere, or cylinder) using Poisson Disk Sampling.
The sampler produces a set of points uniformly distributed in the specified domain such that no two points are closer than a specified distance.
2D domains can also be sampled (rectangle or circle), by setting the size of the domain in the z direction to 0.
