You can either use OpenGL in combination with Performer (tricky) or use
the Performer pfText object to render 2D or 3D text:

  pfFont *font = pfdLoadFont_type1("Helvetica-Bold", PFDFONT_FILLED);
  pfString *string = new pfString;
  string->setFont(font);
  string->setMode(PFSTR_JUSTIFY, PFSTR_LEFT);
  string->setColor(0.0, 0.0, 0.5, 1.0);
  string->setString(tmp_text);
  pfText *text = new pfText;
  text->addString(string);
  scene->addChild(text);

Performer comes with two fonts in /usr/share/Performer/data. Utilities to
create your own fonts can be found on the SGI Developer Toolbox website
(look for Dave Haeberli's font utilities).
