But there could be comparision of mesh with two faces - one with mesh{} and the
same with mesh2{}. Bezier patch is supposed to be generated with external
programs but there is sample for it within scenes/objects.

You can remove some space by replacing "0." with "." but I think you have
considered this. I don't know how many signs are there but perhaps you can also
change negative to positive and positive to negative in vertices and normals and
use scale -1.

I think it could be also good idea to make universal macros to generate
face_indices and uv-vectors for grids like yours within standard include files.
