You should create and scale the sphere at the origin and then move it to the
mesh vertex vector.


// Spheres
#local len = dimension_size(VertexVectors,1) - 1;
#for (i, 0, len)
   sphere { <0,0,0>, 0.04
            texture { pigment {rgb <0.1, 0.3, 0.1>} }
            scale y * 1.2 // Why they moves ?
            translate VertexVectors[i]
  }
