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.
I will look at vtkEdge and eventually consider writing a LIC filter able to
process any data set.
Best regards

We have an implementation of the Lagrangian Eulerian Advection algorithm
published at IEEE Vis 2001. It produces LIC images for steady fields and
time-dependent LIC-like textures with spatial and temporal continuity
for un-steady fields.
Source code, Makefile and test routines are provided for VTK and ParaView.

Dear vtk users,
I`m currently working on a study project about line integral convolution
(LIC).
This is a texture-based technique for effectively displaying 2D and 3D
vector fields.
Has anyone managed to implement this type of filter in vtk ?
As it is to be used in VR-applications, the focus is not so much on
accuracy but rather on efficiency to maintain interactivity.
Thanks very much in advance for any help,
Thomas Brandner

LIC, FLIC and spot noise are in my to-do list. I don't know when I can
get to them though. If someone has implementations, I will be happy to
incorporate them to vtk.
