[vtkusers] Texture Mapping 2D onto 3D

[Tim Hutton]

Hi Heike,

There are two ways to do what you want:

1. Set the texture coordinates of every vertex yourself. (Setting tcoords 
for just a few points won't work.)

2. Use one of the filters that does this for you, eg: vtkTextureMapToPlane. 
There is a tcl example of how to use these filters in 
Examples\VisualizationAlgorithms\Tcl\TransformTextureCoordinates.tcl


Hope this helps!

Tim.
