[vtkusers] Cutting with a PolyLine

[Bruno da Silva de Oliveira]

Hi there,

I would like to know how to cut a vtkDataSet using a polyline. I have 
tried vtkImplicitDataSet for that, using a vtkPolyData containing only 
one polyline and with its point scalars set to 1.0, while setting the 
OutValue of vtkImplicitDataSet to 0.0, in the hope that vtkCutter with a 
cut value of 1.0 would cut exactly in the polyline. It didn't work, no 
polyline was generated by vtkCutter. Studying its algorithm I understood 
why: vtkCutter loops over all the points of the input dataset, 
evaluating the function's value for that point and then contouring the 
resulting dataset with each cut value.

My question is: is there any other way to cut a dataset with a polyline 
without implementing my own polyline function, or is there another way?

Best Regards,
