<br>
thanks for your answer.<br>
But somehow bad news for me :)<br>
<br>
I will try to add this feature than - it might help others, too.<br>
Can you give me some more hints where I can find this mechanism
for sucking textures back from the gpu<br>
and perhaps even how to use it for debugging?<br>
<br>

<div>I think it could be done if you're willing to hack into
PV. There is already some mechanism in there for sucking
textures back from the gpu and writing them to disk for
debugging. It's not exactly what you need but at least will
illustrate pulling data from GPU.<br>
<br>
a potential issue with this idea is that the result from the
LIC is very view dependent, you may be restricted to use
same view settings in your app/blender. maybe better just to
write the LIC shader in blender.<br>

<br>
I am using ParaView for some time now and love its
representation of vector fields on surfaces by<br>
'SurfaceLIC' (<a moz-do-not-send="true"
href="http://www.paraview.org/Wiki/ParaView/Line_Integral_Convolution%29."
target="_blank">http://www.paraview.org/Wiki/ParaView/Line_Integral_Convolution).</a><br>
Beyond that, lots of other representations of scientific
data are of course simply great ....<br>
<br>
I would like to save this textures and the geometrie
(incl. texture coordinates) of the surface<br>
to view it later in our own OpenGL virtual reality
application (or Blender).<br>
<br>
ParaView can load textures (<a moz-do-not-send="true"
href="http://www.paraview.org/Wiki/ParaView:Texture"
target="_blank">http://www.paraview.org/Wiki/ParaView:Texture</a>),<br>
but how can I save them ?<br>
<br>
Does anyone has an idea ... including source code
modifications, which might make things like that
possible.<br>
