e-curvature

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

Defined in local-properties-at-t/curvature/e-curvature.ts:18

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

Parameters:

Name	Type	Description
ps	number[][]	an order 1,2 or 3 bezier curve, e.g. [[[0],[0]],[[1],[1]],[[2],[1]],[[2],[0]]]
t	number	the parameter value where the curvature should be evaluated
