Hallo!
Thanks Claude and IOhannes for the examples !
to clarify: what is wrong with using 2 small rectangles where the selected section is textured to? if i understand your original email correctly, you are trying to avoid this.
No, it is what I want I simply did not know that this is possible with [pix_coordinate].
ok, i see.
However, is there somewhere (opengl-) documentation what exactly the parameters of [pix_coordinate] are ? (which number correspondes to which effect?)
i thought it is covered in the help-patch for [pix_coordinate]
of course, you have to know that there is such an object and that it might approximately do what you want...
Or for which word I should to search to find this in the opengl docu ...
keywords are "texture coordinates"
