Member Function Documentation
| virtual void concepts::QuadSubdiv2V::createChildren | ( | Quad & | q | ) | const [virtual] |
If no children of q exist, they are created.
Implements concepts::QuadSubdivision.
| virtual std::ostream& concepts::QuadSubdiv2V::info | ( | std::ostream & | os | ) | const [protected, virtual] |
Returns information in an output stream.
Reimplemented from concepts::OutputOperator.

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.
- Returns:
- 0 if the new edge with the index i does not exist
Implements concepts::QuadSubdivision.
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.
- Returns:
- 0 if the new vertex with the index i does not exist
Implements concepts::QuadSubdivision.
| 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.
