[vtkusers] Obtain Points from Polydata

[Matias Montroull]

Ok, I was able to get the points by doing this:

              vtkPolyDataNormals skinnormals = vtkPolyDataNormals.New();

skinnormals.SetInputConnection(skinextractor.GetOutputPort());
//skinextractor is a vtkContourFilter
              skinnormals.SetFeatureAngle(90.0);
              skinnormals.ComputePointNormalsOn();

              vtkPolyData polys = new vtkPolyData();

              polys= skinnormals.GetOutput();
              polys.Update();


              for (int i = 0; i < polys.GetNumberOfPoints(); i++)
              {
                  double[] p = new double[3];
                  p=polys.GetPoint(i);
              }
I see each point.

Now... Next question, how do I get the triangles in the mesh??
