Is there a way to fill a void created by objects?

For instance,

I have borders made with primitive objects, with the shape defined by
different splines. They all touch end to end, creating an outline of some
irregular shape. Is there a way to fill in the void between these splines?

Would I have to use a prism (which I am comfortable with), or is there some
concept that I'm not aware of?

Here is a picture of what I'm trying to fill.

I want to fill in the area inside the ninja star, from y = -0.1 to 0.1

Thanks,
nomel

Probably, but as the man said, "you don't want to get there from here".

The problem is that your void is really no different from any other unfilled
space in your scene, and your spline is no help in defining it. It's not
objectively contained by anything.

IMHO you would be better off using basic primitives and CSG to generate your
shape.

For example...

camera {
  location  <0.0, 0, -6.0>
  right     x*image_width/image_height
  look_at   <0.0, 0.0,  0.0>
}


light_source {
  <0, 0, 0>            // light's position (translated below)
  color rgb <1, 1, 1>  // light's color
  translate <-30, 30, -30>
}

// ----------------------------------------


#declare Blade =
difference{
 intersection{
  union{
   cylinder{z*-0.1,z*0.1,1 scale<2.5,1,1>}
   cylinder{z*-0.1,z*0.1,1 scale<2.6,1.1,0.95> pigment{Red}}
  }
  box{<0,0,-0.2>,<-3,1.1,0.2>}
 }
 cylinder{z*-0.2,z*0.2, 1 scale<2.5,0.5,5> translate<-2.75,0,0>}
 cylinder{z*-0.2,z*0.2, 1 scale<2.5,0.5,5> translate<-2.75,0,0> rotate
z*270}
}

#declare Shiriken =
union{
#declare N=0;
#while(N<360)
 object{
  Blade
  rotate z*N
  pigment{Blue}
 }

 #declare N=N+90;
#end
}

object{Shiriken}

Easiest way would propably be to convert all different splines into one 
closed spline and create a prism out of that spline.
