Why the caustics is red? Is it a bug or what?
Sorry about the size of the example, but I couldn't get it any smaller.
(The scene uses photons.inc described in my previous article)
---------------------------------------------------------------------------
#declare phd=3;
#include "photons.inc"
global_settings { max_trace_level 7 }
camera { location -z*30+y*5 look_at x*2 angle 35 }
light_source { -x*200+y*100, 1 spotlight point_at 0 radius 2 falloff 3 }
light_source { <100,60,-200>, .4 Photons(no,no,no) }
plane { y,-6 pigment { checker rgb 1, rgb .7 scale 10 } }
plane { -z,-60 pigment { checker rgb 1, rgb .7 scale 10 } }
union
{ cylinder { -y*5, -y*6, 2.8 }
cylinder { -y*5.5, -y*6, 3.5 }
pigment { rgb <1,.8,.2> }
}
merge
{ difference
{ cylinder { -y*4.9999, y*5, 2.5 }
union
{ cylinder { -y*4, y*5.01, 2 }
torus { 1.5, .5 translate -y*4 }
cylinder { -y*3, -y*4.5, 1.5 }
}
}
torus { 2.25, .25 translate y*5 }
pigment { rgbf <1,1,1,.95> }
finish { phong .5 reflection .2 }
interior { ior 1.5 }
Photons(yes,yes,yes)
}
merge
{ cylinder { -y*4, y*4.00001, 2.00001 }
torus { 1.5, .50001 translate -y*4.00001 }
cylinder { -y*3, -y*4.50001, 1.5 }
pigment { rgbf <.9,1,1,.9> }
finish { phong .5 reflection .1 }
interior { ior 1.33 }
Photons(yes,yes,yes)
}
