It simplifies the drawing of beautiful 1.5 +curves. 1.6 + 1.7 +Using bézier splines an artist can easily draw curves with the same slope on 1.8 +either side of an on-curve point. Spiros, on the other hand, are based on 1.9 +clothoid splines which make it easy to maintain constant curvature as well as 1.10 +constant slope. Such curves will simply look nicer. 1.11 + 1.12 +Raph Levien's spiro splines only use on-curve points and so are easier to use 1.13 +and more intuitive to the artist. 1.14 + 1.15 +This library will take an array of spiro control points and convert them into 1.16 +a series of bézier splines which can then be used in the myriad of ways the 1.17 +world has come to use béziers.
