[vtkusers] Using vtkTriangleFilter to reduce concave polygons to convex

[Alex Southern]

Hi,

The pd1 vtkPolyData contains concave polygons, that I would like to 
reduce into triangles.

vtkTriangleFilter was mentioned as being appropriate, but no actual 
solution was posted.

I want to apply the filter and put triangulated data back into pd2.

If I view pd1 I can see the model, but with flickering due to the 
concave polygons. But pd2 displays nothing -  could someone give me a 
nudge in the right direction?

Cheers
A.

vtkSmartPointer<vtkPolyData> pd1 = vtkSmartPointer<vtkPolyData>::New();
vtkSmartPointer<vtkPolyData> pd2 = vtkSmartPointer<vtkPolyData>::New();
vtkSmartPointer<vtkTriangleFilter> triFilter = 
vtkSmartPointer<vtkTriangleFilter>::New();

triFilter->SetInput( pd1 );
pd2= triFilter->GetOutput();
