Hi!

I am really clueless now.. I want to create a rotating sphere with the
effect seen here: http://users.pandora.be/eclypse/

I jsut dont get the emitting beams right. As soon as i add media the whole
scene is lit bright.
Rotating is working and I cut the holes using sphere... i would appreciate
any hint very much how to do the light emiting from inside the sphere right.

Thank you

Carsten

Here is what i have so far:

light_source {

  color rgb <10,10,10>  // light's color

difference{

  color rgb <1, 1, 1>  // light's color
  hollow

texture {

    finish{

    }
    }

}


// Capped Cylinder, closed [or open ended]
// cylinder { <END1>, <END2>, RADIUS [open] }
//  END1 = coord of one end of cylinder

#declare Index2 = 1;
#while(Index2 <= 10)

#declare Index = 1;
#while(Index <= 10)


cylinder {
  -1*x,  1*x,  0.03
   open
   hollow
   rotate <1,Index2*18,Index*18>

texture {
    finish{
      specular 0.6
    }
  }
}


  #declare Index = Index + 1;
#end

  #declare Index2 = Index2 + 1;
