Does anyone know a way to create "rounded off" text?
When I create a text object using a TTF the edges of the letters are sharp
and I would like to create a rounded or smooth edge to the letters.  Is
there a command/parameter or some way to do this?

Antialiasing would seem to be the preferred technique.  I don't know if
there is a way to do this regionally in POV however.

My recommendation is to check out Elefont. It exports in Moray UDO format
and Pov-Ray INC format. It has many ways of bevelling text.

It's a Win95 application, tho..

There is no built-in function in POV to do something like
this. POV just uses the font in a way like heightfields. If
you really want smooth edges and a font that is not easily
recreated in CSG, maybe you should try to place multiple
versions of the textstring in your scene, scaled in a way
that the edges seem round...

Happy tracing

I would recommend this too.  Elefont meshes will usually render faster than
POV text objects.

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.
