Hi there! I'm Brendan Ryan.
If anyone knows the formula that POV-Ray uses to calculate the normal
vectors for smooth triangles, please let me know. I just want to make
one or two smooth triangle and play around with them.
By the way, I'm using POV-Ray 3.1g in Windows 95.

Check out a similar thread under povray.programming from myself entitled "3d
Geometry--averaging normals"

  Read the help text of the following program:
http://iki.fi/warp/PovUtils/smooth.html
  The calculations are detailedly explained.
  Perhaps the program itself may directly do what you want, though.

-- 
main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/
