[vtkusers] Texture Mapping with 2D Texture Coordinates

[Wenlong Wang]

Hi Youpie,

Thank you very much for your reply.

I tried in your way. But the position of the texture doesn't look right.
The image I used is not the original texture map for the model. So I'm
wondering if that causes the failure. Do I have to pre-process the texture
map?

Many thanks!

Long
