I did not tell you all about my .pov file (that you can find below in this
post). Actually, all triangles where eclosed in a mesh. Texture does not
work, both inside "triangle" and outside it, inside "mesh".
What do you mean when you say "or individually in a special way"? Maybe 2D
objects can be filled in with colours otherwise than by "textures"? This
wuold be the crucial point.

Thank you Bob. I already read this section of Help: it was my starting
point.
Problems actually came after this point.

Sorry, but there are so many groups..... I did not spend a few seconds in
choosing the right one.
But I do not actually find my post in povray.general group nowadays. So,
please excuse me if I post here again.

Here is part of my .pov file:

#include "colors.inc"
#include "shapes.inc"
#include "transforms.inc"

global_settings { assumed_gamma 2.2 }

  panoramic

}

...........
// here I wrote "texture { Material_0001 }" in a second trial, erasing it
from above
