Pointers in wrapped VTK code

[Sarah Macumber]

Hi, some member functions take pointers as arguments like vtkPointSet's method SetPoints :

virtual void     SetPoints (vtkPoints *)

However, C# doesn't do pointers so the following code errors,

vtkPoints p = new vtkPoints();
vtkPointSet pts = new vtkPointSet();
pts.SetPoints(p);

Could not downcast pointer to native class.

Help?

You need to insert points to vtkPoints before you call SetPoints()

Working example:

vtkPoints points = new vtkPoints();
for (int z = 0; z < vecs.Length; z++)
{
   points.InsertPoint(z, vecs[z].ToDouble());
}

vtkPolyData pd = new vtkPolyData();
pd.SetPoints(points);
pd.SetPolys(cells);

vecs - array of Vectors(My class)
