It isn't. The lines you have in mind are part of the mesh. Consider the
mesh as a visual object. This object has a single color for all his
lines. You can set it with Plot3D::setMeshColor and read it with
Plot3D::meshColor. Thats all, I had no intention in giving them more
flexibility. The power of color vectors or otherwise calculated colors
applies only to filled polygons and isolines, not to mesh lines. At
least this is the situation in the current version of qwtplot3d. It
might be, that the feature can be implemented yet with Enrichments
(check the manual the API documentation and the examples for this). If
not, I will provide an example in the next release of the library.

HIH,
