    Hi,

        For axis? I would try a texture (with the letter, x, y, and z). Note
    that the problem I foresee is that it seems you want to follow the
    orientation, but not the "scale". I mean, if you are far from the triangle
    with the "text" on it, the triangle, and the text on it, can become too
    small, or out of the visible frame (cases of zoomings, or observer walking
    too close to origin) while you probably want a "x", "y" and "z" always of
    the same letter sizes, and always in the visible frame, but following the
    real axes, with a very slanted x, as a possible example. That seems to
    involve some interesting mechanics, but I have never really think about that
    particular case, even if I see it as really interesting... :-) Sure, if
    a simple texture does the trick.. that was simple.
