I try to implement a vtkPolyDataAlgorithm filter as plugin in PV. The filter
has 2 inputs: (1) vtkPolyData and (2) vtkImageData. Within the xml-file the
different data types are declared:
<InputProperty
name="3DModel"
port_index="0"
command="SetInputConnection">
<ProxyGroupDomain name="groups">
<Group name="sources"/>
<Group name="filters"/>
</ProxyGroupDomain>
<DataTypeDomain name="input_type">
<DataType value="vtkPolyData"/>
</DataTypeDomain>
</InputProperty>
<InputProperty
name="3DVolume"
port_index="1"
command="SetInputConnection">
<ProxyGroupDomain name="groups">
<Group name="sources"/>
<Group name="filters"/>
</ProxyGroupDomain>
<DataTypeDomain name="input_type">
<DataType value="vtkImageData"/>
</DataTypeDomain>
</InputProperty>
The code compiles without error and the plugin can be loaded into PV. But when
I select the plugin in PV the following error occurs:
ERROR: In ..\..\..\VTK\Filtering\vtkDemandDrivenPipeline.cxx, line 827
vtkPVCompositeDataPipeline (1FBD9388): Input for connection index 0 on input
port index 1 for algorithm vtkCTOAM(1F9E8D80) is of type vtkImageData, but a
vtkPolyData is required.

Obviously, the plugin does only accept polydata as input, because it is based
on a vtkPolyDataAlgorithm filter. Is there a way I could mix both data types as
input to a vtkPolyDataAlgorithm?
