vtk:graph de Reeb &c++

Bonjour a tous,
j'utilise Visual studio 2008 dans mon projet et voila la classe AreaSimplificationMetric pour pouvoir dessiner le graph de Reeb du crâne.

Code:

---

1 2 3 4 5 6 7 8

class AreaSimplificationMetric : public vtkReebGraphSimplificationMetric{ public: vtkTypeMacro(AreaSimplificationMetric, vtkReebGraphSimplificationMetric); static AreaSimplificationMetric* New(); double ComputeMetric(vtkDataSet *mesh, vtkDataArray *scalarField, vtkIdType startCriticalPoint, vtkAbstractArray *vertexList, vtkIdType endCriticalPoint); };
