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>

<div style="direction: ltr;font-family: Tahoma;color:
#000000;font-size: 10pt;">Hello everyone,<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>
<br>
Best,<br>
Jens Henrik<br>
