Detailed Description
Subdivision strategy for quadrilaterals which generates four children.
This is the default subdivision strategy.
The children are generated by subdividing the four edges and introducing four new edges meeting in the middle of the parent quad.

| virtual void concepts::QuadSubdiv4::createChildren | ( | Quad & | q | ) | const [virtual] |
If no children of q exist, they are created.
Implements concepts::QuadSubdivision.

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::QuadSubdiv4::removeChildren | ( | Quad & | q | ) | const [virtual] |
If there are children, they are removed.
The additional edges and vertices are removed as well.
Implements concepts::QuadSubdivision.
