calc-quad-offset-x-point

function calcQuadOffsetCurveXPoint(ps: number[][], D: number): number[] | undefined

Defined in offset/calc-quad-offset-x-point.ts:27

Calculates and returns the point (as the t value) of intersection of the offset curves of a quadratic bezier curve (if any).

• returns undefined if no such point exist

• offset is in normal direction of curve as t goes from 0 to 1

• offset can be negative

• see this Desmos graph (zoom out)

Parameters:

Name	Type	Description
ps	number[][]	an order 1,2 or 3 bezier curve given as an ordered array of its control point coordinates, e.g. [[0,0], [1,1], [2,1], [2,0]]
D	number	distance of offset curve (can be negative)
