DGtal::concepts::CPrimitiveComputer< T > Struct Template Reference

Aim: Defines the concept describing an object that computes some primitive from input points, while keeping some internal state. At any moment, the object is supposed to store at least one valid primitive for the formerly given input points. A primitive is an informal word that describes some family of objects that share common characteristics. Often, the primitives are geometric, e.g. digital planes. More...

struct DGtal::concepts::CPrimitiveComputer< T >

Aim: Defines the concept describing an object that computes some primitive from input points, while keeping some internal state. At any moment, the object is supposed to store at least one valid primitive for the formerly given input points. A primitive is an informal word that describes some family of objects that share common characteristics. Often, the primitives are geometric, e.g. digital planes.
