Hi Max,
the only way to get the picture better would be to (manually) create
geometry with many more vertices to which you can attach relevant
texture coords. Other option would be shader lookup table to go from
input image to output image coords.

Hi all,
I've a question about the interpolation (I guess) computed to set the texture
coordinates given each vertex's one (is that sentence correct?).
It seems the interpolation (or whatever) is done considering the polygon as a
triangle fan.
As my coordinates don't perfectly match, the result is quite ugly.
Here's some screenshots, I highlighted the supposed triangles:

Isn't there a way to compute the coordinates considering the whole polygon
(probably using the barycenter) ?
Is there an option to activate it?
Thanks for all (at least for reading),
