Curved cone

This post has NOT been accepted by the mailing list yet.
hi all,
  i'm trying to make an old motorbike light holder part using openscad.
The item is this:
http://goo.gl/qgHY2g

I start to make it with this simple code:

$fn=30;
difference(){
hull() {union(){
//cerchio iniziale
//cylinder(12.6,30.15,30.15,center=true);
cylinder(30,30.15,30.15,center=true);
//elisse
// resize the sphere to extend 30 in x, 60 in y, and 10 in the z directions.
//resize(newsize=[30,60,10]) sphere(r=10);
translate(v = [-9, 0, 40]) rotate([60,0,270]) resize(newsize=[50.6,85.3,7]) sphere(r=25.3);
//translate([0,0,80])sphere(55);
} 
}
//foro cerchio
//cylinder(12.6,28.05,28.05,center=true,$fn=360);
//pulizia esterno
translate(v = [-11, 0, 40]) rotate([60,0,270]) resize(newsize=[50.6,85.3,7]) sphere(r=25.3);
translate(v = [-13, 0, 40]) rotate([60,0,270]) resize(newsize=[50.6,85.3,7]) sphere(r=25.3);

}

But with hull() is not possible to make a curved line.

Hints?

Thanks

Greetings,

Hey does anyone know of a OpenSCAD code for an aspherical lens? I did a quick search and no luck.

I found what you are asking for on Wikipedia and I have to admit I don't understand the equation. However, if you can express the profile as a standard "f(x)" equation, polar equation, or parametric equations X(T), Y(T), then you can plot it with the OpenSCAD 2D graphing library: http://www.thingiverse.com/thing:11243
