Photons and dispersion don't require a colour map in the light source to
achieve the prism effect anymore!
(I was having a heck of a time setting up a realistic one in MegaPOV, my
cyan kept getting reflected out)

In a similar vein,
plane{z 20texture{pigment{crackle metric.05form x/1e9poly_wave.4color_map{[0rgb

More crackle fun. This pattern would also make a nice tile for stereograms!
#declare F=function{pattern{crackle metric 1}}#declare R=function(x,y,
z,r){F(sin(x/r)*r,y,cos(x/r)*r)}plane{-z,-15 pigment{function{R(x,y,z,
1)}triangle_wave frequency 2}finish{ambient 1}} // crackle variant #21

The command line box is possibly the greatest single enhancement to the
POV editor IMO.
Now all I need is for a 3.5 compliant Moray to be released <grin>
Bye for now,

Use this color map and it will look even better:
color_map{[0 rgb 1][.1 rgb z][.25 rgb 0]}

Maybe crackle needs a new name, I mean what has this to do with "crackle"?
