External module "find-mats"

findMats

• findMats(bezierLoops: number[][][][], maxFlatness?: number, maxLength?: number): Mat[]

• Find the Medial Axis Transforms (MATs) from the given array of bezier loops representing shape boundaries.

  Parameters

  • bezierLoops: number[][][][]

    An array of (possibly intersecting) loops with each loop representing one or more piecewise smooth closed curves (i.e. shapes). Each loop consists of an array of beziers represented by an array of control points with 2,3 or 4 elements corresponding to linear, quadratic and cubic beziers respectively. Each point is a two-element array (ordered pair), the first of which is the x-coordinate and the second the y-coordinate.

  • Default value maxFlatness: number = 1.01

    The maximum value the flatness of a curve can have before an additional MAT point is added in between. Defaults to 1.01. (Flatness is measured as the total distance between control points of a curve divided by the length of the curve. The value cannot be lower than 1.001 and must be less than 2.

  • Default value maxLength: number = 10

    The maximum length a curve can have before an additional MAT point is added in between. Together with maxFlatness it represents a tolerance for the accuracy of the MAT. Defaults to 10. The value cannot be lower than 1 or higher than 1000.

  Returns Mat[]
