Hi(gh)!

Onward with the standard include files and, thus, with the PoV-Ray 
museum of Port Whatmough's Academy of Raytraced Art (ARA)!

When I started to test the neon tubes for the exhibition rooms' 
illumination, I noticed a strange behaviour of the area_light: although 
I defined center and size of the area light correctly, the light 
concentrates in one point! Moreover, the looks_like object (a union of 
two narrow cylinders) is cut in half!

Here is the code:


#declare F_Standard_Indoor =
finish
{
   diffuse 1.15
   brilliance 0.6
}

#declare F_Incandescent =
finish
{
   diffuse 1
   ambient 1
}

#declare T_Simple_White_Incandescent =
texture
{
   pigment { color rgb 1 }
   finish { F_Incandescent }
}


#declare Neon_Tube =
cylinder
{
   0, <2, 0, 0>, 0.025
   texture { T_Simple_White_Incandescent }
}

   plane
   {
     y, 0
     texture
     {
       pigment { MidnightBlue }
       finish { F_Standard_Indoor }
     }
   }

   light_source
   {
     <1, 0.1, 0.06>
     color White
     area_light
     <2, 0, 0>, <0, 0, 0.12>, 5, 2
     adaptive 1
     jitter
     fade_distance 1
     fade_power 2
     looks_like
     {
       union
       {
	object { Neon_Tube translate <0, 0.1, 0> }
	object { Neon_Tube translate <0, 0.1, 0.12> }
       }
     }
   }
   camera
   {
     location <1, 4, 0.06>
     look_at <1, 0, 0.06>
     angle 40
   }

// end of code

Bizarre!

See you in Khyberspace!
