this was made just for fun to test possibilities of proximity pattern
perhaps somebody want improve or/and simplify this stuff for 3D becouse my
current flat usage as pigment should be rather replaced with set of trace of ttf
+ post_process with outline + image_map in scene
unfortunatly ttf font was damaged on S
my picture was traced with winmegapov on old pentium 120 ~9 hours
#macro Outline( Object , Outside , Outline, Inside , Z , N , B , W )
#local F1=function{pigment{proximity{Object,1 samples N sample_bailout B
max_density W*0.51 type 1 method 3 sides 2}}}
#local F2=function{pigment{object{Obj color 0 color 1}}}
#local F3=function{if(F1(x,y,z)-(W/2),if(F2(x,y,z)-0.5,1,0),0.5)}
pigment{ function{ F3(x,y,Z) } color_map {[0 Outside][0.5 Outline][1
Inside]} }
#end
