[vtkusers] constructing dynamic pipelines

[Matthias Langer]

At first, i must confess that my knowlegde about vtk is very limited by
now.

However, i'm working with the vtk-5.1-cvs version and want to know what
kind of design is suggested for dynamicaly creating rendering piplines
like in paraview ? May vtkAlgorithm::GetInutPortInformation(...) /
vtkAlgorithm::getOutputPortInformation(...) be of value for this kind of
problem - and if so, how should i use them ?

How should i find out which mapper object should be used at the end of
the pipline (vtkDataSetMapper, vtkPolyDataMapper, ...) ?

Thanks in advance,
Matthias
