Hello,
     I am working with a mesh object that a program I wrote outputs.  For
some reason, when rendered, the mesh appears not to be shaded at all.  Is
there something I should be doing here in order for this mesh to be shaded?
I realize that you need to use smooth triangle for them to be blended, but
still, the triangles should be shaded light/dark based upon its
angle/distance from light source.

Thanks!

Jason

  Color component values range (usually) from 0 to 1. The value 255 has no
special meaning in the world of povray.
  Your problem is that your color is extremely strong. Try:

  pigment { color rgb<0,0,1>}


  Also your light source is not located in an optimal location to see shading.
Try this:

light_source {   // Spotlight Spotlight001
  <-100,100,200>



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

Warp,
    Thankyou very much.  I cannot believe that I made that mistake. :)
