ShapeUtils

A class containing utility functions for shapes.

Note that these are all linear functions so it is necessary to calculate separately for x, y (and z, w if present) components of a vector.

Methods

.area(contour : Array) → Float

contour — 2D polygon. An array of 2D vectors.

Calculate area of a (2D) contour polygon.

.isClockWise(pts : Array) → Boolean

pts — points defining a 2D polygon.

Note that this is a linear function so it is necessary to calculate separately for x, y components of a polygon.

Used internally by Path, ExtrudeGeometry, and ShapeGeometry.

.triangulateShape(contour : Array, holes : Array) → Array

Used internally by ExtrudeGeometry and ShapeGeometry to calculate faces in shapes with holes.
