If you mean beveled text, try the following macro. The code is modified
from some that Michael Lundahl posted to
comp.graphics.rendering.raytracing a few months ago. 'nbr_of_objects' is
actually the 'smoothness' of the beveling; think of it as anti-aliasing.

bevel_text("Courier","I Want My MTV",0.02, 1.0, 10)

//creates beveled text
#macro bevel_text (bevelFont, bevelText, bevel_depth, text_depth,nbr_of_objects)
   union {
      #local i = 0;
      #while (i < 1)
      //This is the bevel itself
      text { 
         ttf bevelFont, bevelText, bevel_depth, <bevel_depth,0,0>
         matrix < 1, 0, 0,
               0, 1, 0,
               cos(i*2*pi), sin(i*2*pi), 1,
               0, 0, 0 >
      }

      //This is what is behind the bevel. 
      //Set text_depth to 0 if you only want the bevel.
      #if (text_depth > 0)
         text {
            ttf bevelFont, bevelText, text_depth, <bevel_depth,0,0>
            translate <cos(i*2*pi)*bevel_depth, 
                  sin(i*2*pi)*bevel_depth, 
                  bevel_depth>    
         }
      #end
   #declare i = i + 1/nbr_of_objects;
   #end
}
#end
