List of concepts for types related to the Spatial data structures of the library. They allow to discriminate between different Data Structures types and their features.

Collaboration diagram for Space Concepts:

Concepts
concept	vcl::BitProxyConcept
	BitProxyConcept is satisfied only if a class provides the member functions specified in this concept. These member functions allows to access to a bool reference from a bit saved in a mask, and then allow assignment.

concept	vcl::BitSetConcept
	BitSetConcept is satisfied only if a class provides the member functions specified in this concept. These member functions allows to a list of bits encoded in a integral type.

concept	vcl::ColorConcept
	ColorConcept is satisfied only if a class provides the member functions specified in this concept. These member functions allows to access to the color components of a given color.

concept	vcl::PointConcept
	Concept for types representing points in Euclidean space.

concept	vcl::Point2Concept
	Concept for points in two-dimensional space.

concept	vcl::Point3Concept
	Concept for points in three-dimensional space.

concept	vcl::Point4Concept
	Concept for points in four-dimensional space.

concept	vcl::PointIteratorConcept
	Concept for iterators that iterate over Points (class that satisfies the vcl::PointConcept).

concept	vcl::Point2IteratorConcept
	Concept for iterators that iterate over 2D Points (class that satisfies the vcl::Point2Concept).

concept	vcl::Point3IteratorConcept
	Concept for iterators that iterate over 3D Points (class that satisfies the vcl::Point3Concept).

concept	vcl::Point4IteratorConcept
	Concept for iterators that iterate over 4D Points (class that satisfies the vcl::Point4Concept).

concept	vcl::PrincipalCurvatureConcept
	Concept for types representing principal curvature directions and values at a point on a 3D surface.

concept	vcl::TriangleConcept
	Concept for types representing triangles in Euclidean space.
