[vtkusers] Need point position on texture

[John Biddiscombe]

Why not pass the points through TextureMapToPlane? Points->Plane
definition->Tex coords output.

Hi,

I have written some piece of code to draw lines on
a texture which works good (see picture).
Okay, actually I am not drawing ON the texture, I draw
IN FRONT OF the texture.
But the problem is, that I need the texture coordinates of
the points.
I can switch between world and display coordinates but how
to I get the corresponding point of/in the texture ?

Any hints are welcome...

greets
  Ingo
