[Paraview] Cone as input and Sphere as output for plugin filter

[Moreland, Kenneth]

Call sphere->Update() after SetRadius but before GetOutput.

Subject: [EXTERNAL] [Paraview] Cone as input and Sphere as output for plugin filter

Hi All

I would like to implement a polydataalgorithm filter which takes a polydata as input (a cone), does some calculations and produces a sphere as output of the plugin algorithm. Unfortunately, instantiation of the sphere seems to be of a problem, as the output remains empty.

This is what I am doing:

int vtkTestSphere::RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
{
   vtkSmartPointer<vtkSphereSource> sphere =  vtkSmartPointer<vtkSphereSource>::New();
   sphere->SetRadius(50);
   this->GetOutput()->DeepCopy(sphere->GetOutput());


  return 1;
}


Any help would me much appreciated!

Regards, Peter.
