I would put a .pov file latter.
But show you first here.
Like this:
#declare pts =
array[4]{
<0,0,0>,<0.3,0,0>,<0.7,0,0>,<1,0,0>
}
#declare rs =
array[4]{
0.1,0.2,0.15,0.1
}
object{
Shape_Bezierpoints_Sphere_Sweep(yes, 20, pts, rs)
}

Basically each control point corresponds with one radius. Like the example, the
position at the first control point is the first radius. The second and the
third radii represent the trend. And the fourth radius represents the radius at
the fourth control point.
