Detailed Description

Subdivision strategy for infinite quadrilaterals which generates two children which are infinite quadrilaterals as well.

The parent quad's horizontal axis is subdivided, the vertical is not.

Member Function Documentation

createChildren()

virtual void concepts::InfQuadSubdiv2V::createChildren ( InfiniteQuad &  q ) const

virtual

If no children of q exist, they are created.

Implements concepts::InfQuadSubdivision.

info()

virtual std::ostream & concepts::InfQuadSubdiv2V::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

newEdge()

virtual Connector1 * concepts::InfQuadSubdiv2V::newEdge ( const InfiniteQuad &  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	InfiniteQuad 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::InfQuadSubdivision.

newVertex()

virtual Vertex * concepts::InfQuadSubdiv2V::newVertex ( const InfiniteQuad &  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	InfiniteQuad 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::InfQuadSubdivision.

removeChildren()

virtual void concepts::InfQuadSubdiv2V::removeChildren ( InfiniteQuad &  q ) const

virtual

If there are children, they are removed. The additional edges and vertices are removed as well.

Implements concepts::InfQuadSubdivision.
