1 Spiro is the creation of Raph Levien. It simplifies the drawing of beautiful

|
2 curves.

4 Using bézier splines an artist can easily draw curves with the same slope on
|
al@17914
|
5 either side of an on-curve point. Spiros, on the other hand, are based on
|
al@17914
|
6 clothoid splines which make it easy to maintain constant curvature as well as
|
al@17914
|
7 constant slope. Such curves will simply look nicer.

9 Raph Levien's spiro splines only use on-curve points and so are easier to use

10 and more intuitive to the artist.
