Hi everybody,<br><br>I would like to implement a filter to ParaView which calculates the radius of curvature of streamlines. <br><br>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<br>
<br><i>No points/cells to operate on</i>. <br><br>Maybe you could point me to a source where the functionality of vtkCurvatures is explained in detail and the usage described. <br><br>Thanks a lot,<br>Natalie<br></div><div>
