I have bit of a problem with this:

and I got a better fit with:

#declare Line = 0.02;
#declare Torus = torus {sqrt(3)/8, Line rotate x*90 translate <0.5, 
sqrt(3)/6, 0>}

...which is less elegant but which fits better the triangle centres 
somehow. I don't know how to translate this to your solution though.

I use the following mesh to get the image (with the necessary colour 
changes which I prefer):

mesh {
  triangle {
   <0, 0, 0>, Mid, x
   uv_vectors <0, 0>, Mid, <1, 0>
   texture {Test}
  }

   triangle {
   FZero+hx, FMid+hx, FX+hx
   uv_vectors <0, 0>, Mid, <1, 0>
   texture {Test}
  }

  triangle {
   <0, 0, 0>+x, Mid+x, x+x
   uv_vectors <0, 0>, Mid, <1, 0>
   texture {Test}
  }

  texture {pigment {rgb 1}}
  translate <-1, -1, 0>
}
