Detailed Description

template<typename TVRef, typename TFRef, typename TPrimalData, typename TDualData, bool PrimalDual = true>
class itk::GeometricalQuadEdge< TVRef, TFRef, TPrimalData, TDualData, PrimalDual >

This class extends the QuadEdge by adding a reference to the Origin.

The class is implemented in such a way that it can generate its own Dual. In a physical edge, there will be four GeometricalQuadEdge. Two of them will be Primal and two will be Dual. The Primal ones are parallel to the physical edge and their origins relate to the mesh points. The Dual ones are orthogonal to the physical edge and their origins relate to the faces at each side of the physical edge.

The only purpose of the last paramater of the template is to guarantee that the two types GeometricalQuadEdge and GeometricalQuadEdge::Dual are always different (in the sense that their typeid() are different). If we only had the four first parameters and assume that GeometricalQuadEdge gets instantiated with types such that TVRef = TFRef and TPrimalData = TDualData then this instantiation GeometricalQuadEdge and GeometricalQuadEdge::Dual would be the same types (this is simply due to the very definition of GeometricalQuadEdge::Dual). This would in turn make the types QEType and QEDual of QuadEdgeMesh identical and would prevent any algorithm requiring to distinguish those types (e.g. by relying on a dynamic_cast<QEType*>) to be effective. This justifies the existence of last dummy template parameter and it's default value.
