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

Not my invention and not a very fast method but easy to tweak:

use a graphics program like PaintShop to create an image of the text, blur it,
then use that as a heightfield. Use the water level to cut of the background.
Use the same heightfield inversed to give the text a backside.

Not long ago there was an example doing this in the binaries-images group (with
the SGI-logo), but I can't remember by who.

Good luck,

Remco

If what you are talking about is like "beveled" text, go to dejanews and
look for bevel in the POV-Ray newsgroup. There are at least two examples
there, one for POV 3.0 and one for POV 3.1.

  There better not be any reference to a pov-ray newsgroup
at dejanews. This is a closed server and does not appear
on usenet. If it does someone should report it to the povray
admin team immediatly. Perhaps you mean c.g.r.r. or one of
the other subject groups on this server ?

Dejanews accumulated an archive from the period when there
was a USENET leak on the povray news server.  This was later
currected, so the Dejanews archive terminates in September.

I meant comp.graphics.rendering.raytracing. Which is not a POV-Ray
newsgroup (although POV-Ray is on topic within it) and I have no idea why
I used that phrase.

Ken is getting sloppy in his high output volume.

Of course there are references to news.povray.org in dejanews.  A quick check will
reveal
that.  They were archived during the leak, which was acknowleged and fixed
by the administrators.  But it will take years for that section of the archive to
be purged.

Say WHAT ? I thought it was a fair and reasonable warning and
also appended the statement saying I thought Jerry had simply
made a mistake in his reference to the newgroup in question.
It appears I have been vendicated since that is indeed what
heppened.

It is because of that snafu that I took the defensive on the
Pov teams behalf.

Getting sloppy my rendered tush !

Ahh -- you said there should be "no reference" to povray newsgroups....
I did a quick search for text references as follows :

http://www.dejanews.com/dnquery.xp?ST=PS&QRY=text&defaultOp=AND&DBS=1&format=terse&showsort=score&maxhits=25&LNG=ALL&subjects=&groups=povray.*&authors=&fromdate=&todate=

... plenty of matches.  It is true there should be no references to recent articles,
but
I still maintain your statement was a bit hasty.

Granted -- you were correct that the original recommendation was a typo.  I'm just
being picky because I have too much to do at work and need to get out my frustrations
:).

Just keep saying to yourself "I am not a machine ! I am not a machine !".
