[vtkusers] Create a curvilinear curve

[toulgen]

Hi,

 

I have n points:

 

----------------------------------------------------------------------------
-------------------

vtkPoints* temp_pts = vtkPoints::New(); // XYZ coords 

            temp_pts->InsertPoint(0, 20,20,20);

            temp_pts->InsertPoint(1, 20,512,20);

            temp_pts->InsertPoint(2, 512,512,20);

            temp_pts->InsertPoint(3, 512,20,20);

            temp_pts->InsertPoint(4, 20,20,20);

            temp_pts->InsertPoint(0, 20,20,300);

            temp_pts->InsertPoint(1, 20,512,300);

            temp_pts->InsertPoint(2, 512,512,300);

            temp_pts->InsertPoint(3, 512,20,300);

----------------------------------------------------------------------------
-------------------

 

With the following code I create a polyline:

----------------------------------------------------------------------------
-------------------

            // Create the polyline. 

            vtkCellArray *lines = vtkCellArray::New(); 

            int numPoints = temp_pts->GetNumberOfPoints(); 

            lines->InsertNextCell(numPoints); 

            for (int j = 0; j < numPoints; j++) 

                        lines->InsertCellPoint(j); 

 

            vtkPolyData *profileData = vtkPolyData::New(); 

            profileData->SetPoints((vtkPoints *)(temp_pts)); 

profileData->SetLines(lines);

 

            //profileData->GetPointData()->SetScalars(scalars); 

            profileData->BuildLinks();

----------------------------------------------------------------------------
-------------------

 

I want to create a curvilinear curve with my n points.

It is possible?

 

Thx.
