Class ShapeUtils

A class containing utility functions for shapes.

Remarks

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.

new ShapeUtils(): ShapeUtils
Returns ShapeUtils

Methods

`Static`area

area(contour): number
Calculate area of a ( 2D ) contour polygon.
Parameters
- contour: readonly Vector2Like[]
Returns number
- Defined in ../node_modules/@types/three/src/extras/ShapeUtils.d.ts:13

`Static`isClockWise

isClockWise(pts): boolean
Note that this is a linear function so it is necessary to calculate separately for x, y components of a polygon.
Parameters
- pts: readonly Vector2Like[]
Returns boolean
Remarks
Used internally by THREE.Path | Path, THREE.ExtrudeGeometry | ExtrudeGeometry and THREE.ShapeGeometry | ShapeGeometry.
- Defined in ../node_modules/@types/three/src/extras/ShapeUtils.d.ts:19

`Static`triangulateShape

triangulateShape(contour, holes): number[][]
Used internally by THREE.ExtrudeGeometry | ExtrudeGeometry and THREE.ShapeGeometry | ShapeGeometry to calculate faces in shapes with holes.
Parameters
- contour: Vector2Like[]
- holes: Vector2Like[][]
Returns number[][]
- Defined in ../node_modules/@types/three/src/extras/ShapeUtils.d.ts:24
