Hi everybody,
I would like to implement a filter to ParaView which calculates the radius of
curvature of streamlines.
I've browsed a little and found that there is already a curvature filter, which
calculates the Gaussian curvature and the mean curvature using vtkCurvatures.
This is nearly what I need, but somehow, I cannot apply it to the streamlines,
I get the error message
No points/cells to operate on.
Maybe you could point me to a source where the functionality of vtkCurvatures
is explained in detail and the usage described.
Thanks a lot,
Natalie
