Hello, I'm new to vtk and this user group. Very much in learning stage.

I have been trying to triangulate unstructured surface data point.

I have been using vtkDelaunay3D

vtkFloatPoints *startPoints = vtkFloatPoints::New();
vtkPolyData *inputDataSet;

.....//read data from a file.

inputDataSet = vtkPolyData::New();

inputDataSet->SetPoints(startPoints);

vtkDelaunay3D *del = vtkDelaunay3D::New();
del->SetInput(inputDataSet);
del->SetTolerance(0.001);

when it comes to this line the following error accord

vtkPolyDataMapper *mapMapper = vtkPolyDataMapper::New();
mapMapper->SetInput(del->GetOutput());
error C2664: 'void __thiscall vtkPolyDataMapper::SetInput(class vtkPolyData *)'
: cannot convert parameter 1 from 'class vtkUnstructuredGrid *' to 'class vtkPolyData *'

or is it the way I'm doing here is wrong?

Does anybody know how I can overcome this error

Any help will be very welcome.

Thank you in advance.

Chandra.
