Poking around, this actually already exists: the potential pigment

for example:

box {
  <-0.5, -0.5, 0>, <0.5, 0.5, 0>
  texture {
    pigment {
      potential {
        blob {
          threshold 0.6
          sphere { <.75, 0, 0>, 1, 1 }
          sphere { <-.375, .64952, 0>, 1, 1 }
          sphere { <-.375, -.64952, 0>, 1, 1 }
          scale 0.25
        }
      }
      color_map {
        [0.0 color rgb 0.0 ]
        [1.0 color rgb 1.0 ]
      }
    }
    finish {
      ambient 1.0
      diffuse 0.0
    }
  }
}

I rendered this with an orthographic camera and attached the output.
