I do know this work and I have installed it, it works well but requires a vtkImageData set as input, which does not meet my own requirements since I would like to apply it to a slice, ie a vtkPolyData set.<br>I will look at vtkEdge and eventually consider writing a LIC filter able to process any data set.<br>Best regards<br><br><hr id="stopSpelling">Date: Tue, 15 Sep 2009 09:38:16 +0200<br>From: tfroebel@gmx.de<br>To: paraview@paraview.org<br>Subject: Re: [Paraview] Fast-LIC implementation - where are we?
