curvature

function curvature(ps: number[][], t: number): number

Defined in local-properties-at-t/curvature.ts:17

Returns the curvature κ of the given linear, quadratic or cubic bezier curve at a specific given parameter value t.

• returns Number.NaN at a cusp - this can be tested for with Number.isNaN

Note!

Green circles are draggable!
