converted to grayscale ?
hmmm, wait a minute
look below at my code used with my eschered patterns in p.b.i
#local FunPig1=function{pigment{object{Obj1 color 0 color 1/3}}}
#local FunPig2=function{pigment{object{Obj2 color 0 color 2/3}}}
#local FunPig3=function{pigment{object{Obj3 color 0 color 1}}}
these values 1/3, 2/3 and 1 are in rgb space - each equal for red,
green, blue, right ?
but converted to grayscale they are not this values for gray, right ?
than if I want to simple attach this map to my pattern
texture_map{[0 T_Gold_3C][1/3 T_Grnt24][2/3 T_Wood33][1 T_Silver_3C]}
this is rather not what I want ?
than there should be also in POV function grayscale( color ) with
exactly the same algorithm
