A nullptr-initialized pointer to an IMP Object.
A smart pointer to a ref-counted Object that is a class memeber.
Definition: base/Pointer.h:147
Compute a distance metric between two points.
double get_distance(const Plane3D &pln, const Vector3D &p)
Return the distance between a plane and a point in 3D.
Definition: Plane3D.h:68
#define IMP_OBJECT_METHODS(Name)

Cluster sets of points.
A base class for clustering results where each item is in one cluster.
Store data to be clustered for distance metric based algorithms.
