Version 3 of BesselHorn curve script has some minor changes.
1. Added Conical horn curve line. It is just a line, which revolves to a cone, or frustum.
Flare slider has no effect.
2. Added exponential horn curve. It is calculated with positive x values, and so lies to the right of the y-axis, automatically.
There is only one exponential curve between the two endpoints, so flare slider has no effect.
eFlare is the calculated flare for the exponential curve, for given parameters.
3. Shifted Bessel and Conical curves to right of y-axis. So all 3 curves have the same endpoints, for given set of parameters,
and there is less jumping around with changing parameters.
In the event a multi curve horn is created, the multiple curves would need to be placed sequentially, end to end.
A nodeeditor version used multiple times, each with its own parameters, might permit multiple joined segments, in a single node program. (Or multiplex mode...)
