I'll answer with one complete simple solution, but if you're asking about
something more than what's shown below feel free to ask more.

/* BEGIN simple hemisphere */

camera {location -4*z look_at 0}

light_source {-100*z,1}

#declare Hemisphere=
intersection {
  plane {-y,0} // could use x, instead of y, for East/West
 // negative y for northern hemisphere, positive for southern
  sphere {0,1}
  pigment {color rgb <1,1,1>}
}

object {Hemisphere
  rotate < 15 , 0 , 0 > // to turn whichever way needed
  translate -1.25*x} // put on left side

/* and to hollow it out... */

difference {
  object {Hemisphere}
  sphere {0,1 // cutaway object
   pigment {color rgb <1,0,0>}
   scale 0.9 // scale for thickness ( nearer 1 is thinner)
   }
  rotate < 15 , 0 , 0 > // to turn whichever way needed
  translate 1.25*x // put on right side
}

/* END */
