al@17914 | 1 Spiro is the creation of Raph Levien. It simplifies the drawing of beautiful |
al@17914 | 2 curves. |
al@17914 | 3 |
al@17914 | 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. |
al@17914 | 8 |
al@17914 | 9 Raph Levien's spiro splines only use on-curve points and so are easier to use |
al@17914 | 10 and more intuitive to the artist. |
al@17914 | 11 |
al@17914 | 12 This library will take an array of spiro control points and convert them into |
al@17914 | 13 a series of bézier splines which can then be used in the myriad of ways the |
al@17914 | 14 world has come to use béziers. |
