This might help if you use MegaPov:
#version unofficial MegaPov 0.4;
background {rgb 1}
sphere_sweep {
b_spline_sphere_sweep,
6,
<-5, -5, 0>, 0
<-5, 2.5, 0>, 0.1
<-2.5, 5, 0>, 0.5
< 2.5, -5, 0>, 1
< 5, -2.5, 0>, 1.5
< 5, 5, 0>, 3
// sphere_sweep_depth_tolerance 1.0e-3
pigment {rgb 0}
scale <1,1,0.01>
}
light_source { <-10,10,-10>, 1}
camera {
location <1,1,-15>
angle 67
look_at <0, 0, 0>
}
You could adjust the sphere positions and sizes to get what you're looking for I
believe. If using POV-Ray 3.* I could only suggest using 'height_field' and/or
'image_map' with a drawing of the shape you need. Don't know if there might be
yet another way.

| Dear all,
|
| I am trying to work out which of the various patches I need to do
| the following.
|
| I want to draw a curved line between two points varying the
| thickness
| of the line as I go as if the line was drawn with a flat nibbed pen;
| thinner at the
| ends and fatter in the middle. The object I want is a slur used to join
| two notes
| or above a musical phrase.
|
| I have looked through lot's of posts but I am still non the wiser as
| the maths is
| all a bit confusing.. Any pointers or better still a macro I can
| experiment with
| would be most educational.
|
| Regards,
|
| Nigel.
