Detailed Description

template<unsigned int N, class T>
class vigra::Polytope< N, T >

Represent an n-dimensional polytope.

Template Parameters

N	Dimension the polytope.
T	Type of the vector components of the polytope vertices.

Constructor & Destructor Documentation

Polytope() [1/2]

template<unsigned int N, class T>

Polytope

(

)

Default constructor creates an empty polytope class.

Polytope() [2/2]

template<unsigned int N, class T>

Polytope

(

const Polytope< N, T > &

other

)

Copy constructor.

Member Function Documentation

operator=()

template<unsigned int N, class T>

virtual void operator= ( const Polytope< N, T > & other )

virtual

Copy from another polytope.

closed() [1/2]

template<unsigned int N, class T>

virtual bool closed ( const node_type n ) const

virtual

Check if the facet aligns with other facets at each of its ridges.

closed() [2/2]

template<unsigned int N, class T>

virtual bool closed ( ) const

virtual

Check if the polytope has a closed surface

addVertex()

template<unsigned int N, class T>

virtual node_type addVertex ( const point_view_type & p )

virtual

Add a vertex to the polytope.

eraseFacet()

template<unsigned int N, class T>

virtual void eraseFacet ( const node_type u )

virtual

Erase a facet.

getConnected()

template<unsigned int N, class T>

virtual std::set< node_type > getConnected ( const node_type u ) const

virtual

Get the connected elements in the graph that represents the polytope. If a facet node is inserted, all of its vertices will be returned, if a vertex node is inserted, all facets having this vertex will be returned.

litFacets()

template<unsigned int N, class T>

virtual ArrayVector< node_type > litFacets ( const point_view_type & p ) const

virtual

Get all facets whose normal has a positive scalar product with the vector to the given vertex.

tidyUp()

template<unsigned int N, class T>

virtual void tidyUp ( )

virtual

Remove all vertices that are not part of the polytope mesh.

distance()

template<unsigned int N, class T>

virtual real_type distance ( const node_type u, const point_view_type & p ) const

virtual

Get the distance between a facet and a vertex

fill() [1/2]

template<unsigned int N, class T>

virtual unsigned int fill ( MultiArrayView< N, unsigned int > & array, const unsigned int label, const point_view_type offset, const point_view_type scale ) const

virtual

Label all elements in the array which are inside the polytope.

fill() [2/2]

template<unsigned int N, class T>

virtual unsigned int fill ( MultiArrayView< N, unsigned int > & array, const unsigned int label, const point_view_type offset ) const

virtual

Label all elements in the array which are inside the polytope.
