#include <sampling/sampledSet.H>

Detailed Description

Holds list of sampling points which is filled at construction time. Various implementations of this base class to e.g. get sampling points at uniform distance along a line (uniformSet) or directly specified (cloudSet)

Each 'sampledSet' has a name and a specifier of how the axis should be write (x/y/z component or all 3 components)
