Okay, I've reduced the scene greatly:
//Start of scene
camera {location -5*z}
background{color rgb 1}
light_source {<-10, 10, -10> color rgb 1}
merge{
quadric {<1, -1, 1>, <0, 0, 0>, <0, 0, 0>, 0 clipped_by{plane{y,-1}}}
sphere{0,1 scale <1,3,1>}
pigment {color rgb .5}}
//End of scene
See if this helps any.
