The object pattern is similar to a block pattern like checker or hexagon
but the list items have to be inside the object{} block and are not
optional.

For syntax see section 6.8.3.2 and 6.7.11.23:

sphere {<0,0,0>,10 hollow 
  material {
    interior {
      media {
        emission .1
        density { 
          object {
            box {<0,0,0>,<2,2,2>}   
            density {rgb<1,0,0>}
            density {rgb<0,0,0>}  
          }    
        }
      }
    }  
    texture { pigment { color rgbt 1 } }
  }
}
