<p class=MsoNormal>Hi there I have recently ported over from vtk 4.0 using VS6
to vtk5.2 on vs2008.<o:p></o:p></p>
<p class=MsoNormal>Issues have been plentiful but this one I can’t seem
to understand. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have code that generates a (vtkPolyData) surface which has
a texture applied to it from a generated vtkImageData object BUT the surface
texture appears completely black. As far as I can see both the image data and
the surface are generated with no issues and are exactly the same as in the
previous environment.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The code I’m using for this is :<o:p></o:p></p>

<p class=MsoNormal>I can’t see anything wrong with this code and it works
perfectly in the previous environment. Can anyone think of anything that I
should look into for this issue?????<o:p></o:p></p>

<p class=MsoNormal>Many thanks in advance.<o:p></o:p></p>
