Or you might consider building a heart shape from two half blobs. I'm no
blob expert, but I've managed to knock this together fairly quickly. It
could probably be considerably improved by adjusting some of the
numbers, particularly those defining the sphere components.


global_settings {assumed_gamma 1.0}
camera {location  <0,0,-3> look_at <0,0,0> angle 50}
background {rgb 1}
light_source {<-30, 100, -30> color rgb 1}

#declare Half = intersection {
  blob {
    threshold 0.9                       // tweak me
    sphere { < 0.3, 0.4, 0>, 1,1.2 }    // tweak me
    sphere { <-0.4,-0.4, 0>, 1.2,1.2 }  // tweak me
    //sturm
  }
  plane {-x,0}
}

#declare Heart = union {
    object {Half}
    object {Half scale <-1,0,0>}
  scale <1,1.15,0.5>                    // tweak me
}

object {Heart
  pigment {rgb <0.9,0.1,0.1>}
  finish {phong 1 phong_size 10}
}
