<p class=MsoNormal>The vtkActor has a SetTexture method that allows you to
associate a vtkTexture<br>
object with polydata. The vtkTexture is essentially a mapper that takes a<br>
vtkImageData and turns it into an OpenGL texture.<br>
<br>
The vtkPlaneSource should produce a polydata that already has the proper<br>
texture coordinates to map the points of the plane to the corners of the image.<br>
There is also a vtkTextureMapToPlane filter that can be used to add texture<br>
coordinates to a polydata.<br>
<br>
AFAIK none of the VTK file formats allow textures to be stored with polydata,<br>
but they will at least save the texture coordinates.<br>

Hm, I'm not sure that will help. Let me explain what I am actually trying to
do. I have a text file with 50 sets of camera parameters (describing 50 camera
positions and orientations). I have a folder of 50 images - one for each
camera. What I am trying to do is create a plane for each camera and texture
map the corresponding image onto the plane. Then I want to load the scene in
paraview. You can see how I wouldn't want to select manually 50 images to map
onto each of the planes. I actually don't even know how that would work if
there is more than 1 plane in the polydata (if I used vtkAppendPolyData).<br>
<br>
Do anyone have any other suggestions now that you know the full story?<br>
<br clear=all>
Thanks,<br>
<br>
