Re: [Paraview] Filter driven from two inputs

[Robert Maynard]

You can set the number of inputs to a filter in the constructor. Like this: this->SetNumberOfInputPorts ( 2 ); Than in the RequestData you will have to do something like this: vtkInformation *inInfo = inputVector[0]->GetInformationObject ( 0 );   vtkInformation *sourceInfo = inputVector[1]->GetInformationObject ( 0 );   vtkInformation *outInfo = outputVector->GetInformationObject ( 0 );   // get the input and ouptut   vtkDataSet *input = vtkDataSet::SafeDownCast (                           inInfo->Get ( vtkDataObject::DATA_OBJECT() ) );     vtkPolyData *source = vtkPolyData::SafeDownCast (                         sourceInfo->Get ( vtkDataObject::DATA_OBJECT() ) );       vtkPolyData *output = vtkPolyData::SafeDownCast (                          outInfo->Get ( vtkDataObject::DATA_OBJECT() ) ); Gregory D Abram wrote: Is there a way to drive a filter from two inputs? I'd like to derive a planar equation from one filter and use it to specify a cut plane slicing a the result from a different filter. Any pointers?
