Member Function Documentation

createChildren()

virtual void concepts::QuadSubdiv2V::createChildren ( Quad &  q ) const

virtual

If no children of q exist, they are created.

Implements concepts::QuadSubdivision.

info()

virtual std::ostream& concepts::QuadSubdiv2V::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

instance()

static const QuadSubdiv2V* concepts::QuadSubdiv2V::instance ( )

static

newEdge()

virtual Edge* concepts::QuadSubdiv2V::newEdge ( const Quad &  q, uint  i  ) const

virtual

Returns the ith edge which has been newly created by the subdivision.

An edge which is the result of a refinement is not newly created.

Parameters

q	Quad which has been refined
i	Index of the new edge

Returns

0 if the new edge with the index i does not exist

Implements concepts::QuadSubdivision.

newVertex()

virtual Vertex* concepts::QuadSubdiv2V::newVertex ( const Quad &  q, uint  i  ) const

virtual

Return the ith vertex which has been newly created by the subdivision.

An vertex which is the result of a refinement (ie. of an edge) is not newly created.

Parameters

q	Quad which has been refined
i	Index of the new vertex

Returns

0 if the new vertex with the index i does not exist

Implements concepts::QuadSubdivision.

removeChildren()

virtual void concepts::QuadSubdiv2V::removeChildren ( Quad &  q ) const

virtual

If there are children, they are removed.

The additional edges and vertices are removed as well.

Implements concepts::QuadSubdivision.
