length
function length(interval: number[], ps: number[][], maxCurviness?: number, gaussOrder?: 4 | 16 | 64): number
Defined in global-properties/length/length.ts:23
Returns the curve length (for a linear, quadratic or cubic bezier curve) in the specified interval calculated using Gaussian Quadrature with adaptive subdivision for improved accuracy.
Note!
Green circles are draggable!
Parameters:
| Name | Type | Default value | Description |
|---|---|---|---|
interval | number[] | - | the paramter interval over which the length is to be calculated (typically [0,1]) |
ps | number[][] | - | an order 0,1,2 or 3 bezier curve given as an array of its control points, e.g. [[1,2],[3,4],[5,6],[7,8]] |
maxCurviness | number | 0.4 | optional maximum 'curviness' (defined as the total angle change between consecutive line segments between the curve control points) before subdivision occurs; defaults to 0.4 radians |
gaussOrder | 4 | 16 | 64 | 16 | the optional order of the Gaussian Quadrature performed between curve segments; defaults to 16; can be 4,16 or 64 |
