Hi Seb! I found out that the following works without having the need to access the C++ API explicitly and this is what I am using now:
from paraview.simple import * LoadPlugin("libSurfaceLIC.so",ns=globals()) [...] view = GetRenderView() source = GetActiveSource() rep = Show(source,view) rep.Representation = 'Surface LIC' rep.SetPropertyWithName('LICIntensity',0.9) rep.SetPropertyWithName('LICStepSize',0.5) view.StillRender() [...] I discovered that the Surface LIC properties of the rep object are listed when calling print rep.ListProperties(). Their respective values can be output with rep.GetPropertyValue("<Property name>"). Cheers, Frank. -----Original Message----- From: Sebastien Jourdain [mailto:sebastien.jourd...@kitware.com] Sent: Donnerstag, 26.
