   converting 3d point to 2d point (screen coord)
  hi,I'm using bitmapfonts to display on screen information.  However I want the text to display at the position of a 3d vertex.So what do I need to know to convert the (x,y,z) world coord to (x,y) screen coords.thanks,Scott   
  Is this what you're trying to do?   ;  ahem... yes.  thank you.  i have a function for converting 2d to 3d coords which uses gluUnProject.  i forgot there was an gluProject as well.thanks,Scott
