450

|
452
|
|
|
* // pie slice and continue down to 6'a clock. |

* // |
|
454

|
* // In the algortithm this is done in three principal steps |

455

|
|
* // Step 1. Do the knife cut to ensure by splitting slices that extends |
|
456
|

|
457
|

* // |
|
461
|
|
|
* // The thing that slightly complicates this scheme with all the |
|
462
|
|
|
* // angle comparisons below is that we can have an arbitrary start |

463
