generate-arc-from-cubics
function generateArcFromCubics(c: number[], p1: number[], p2: number[]): number[][][]
Defined in create/generate-arc-from-cubics.ts:43
Returns an arc approximation using unit quarter circle cubic bezier curves. The result is returned as an array of cubic bezier curves.
- if the last returned arc is approximately smaller than 2**-40 of a quarter circle it is not added to the returned value
- if the last returned arc is approximately (1 - 2**-40) of a quarter circle a full quarter circle is added to the returned value
Parameters:
| Name | Type | Description |
|---|---|---|
c | number[] | arc circle center |
p1 | number[] | arc goes from this point |
p2 | number[] | to a point on a line from c to this point (since the problem is over-specified) (if p2 lies on the ray from c through p1 (or p2 equals c) a full circle is generated using 4 cubic bezier curves; if p2 lies on the opposite ray a half circle is generated) |
