Again !
It seems that further release should include this kind of function .

Any way, because it is GL call it is easy to pass through.
in the post draw callback process call cmov(your 3D coordinate)
and then use charstr or fmpstr(your string);
Don't forget to push and pop current GR state.

Take care, cmov has an undefined return if the object is out of the window.
( generally return the last define set of coordinates )

Unfortunatly, if you re running with OpenGL call, it is harder !!
see last month FAQ , Nicolas Gauvin mailed a good paper
(entry header : world coord -> screen coord )
