Thanks a lot Mike!

It works very well and quick too!

Only, I found it was even quicker if you change line 36 to line 40 from
this:

  #if (_ikn_len > ikn_length)
    #declare _ikn_m = _ikn_m * 0.5;  // if spline too long, reduce end
vectors
  #else
    #declare _ikn_m = _ikn_m * 1.5;  // if spline too long, increase end
vectors
  #end

to this:

  #declare _ikn_m = _ikn_m*(ikn_length/_ikn_len);

Then you can easily go down to 0.01% precision and then it's still quicker.

I'll use your method to find the right spline and then Peter Popov's to
equalize the points. :-)

Greetings,

Rune
