Constructors

constructor

new CubicBezierCurve3(v0: THREE.Vector3, v1: THREE.Vector3, v2: THREE.Vector3, v3: THREE.Vector3): CubicBezierCurve3
Parameters
- v0: THREE.Vector3
- v1: THREE.Vector3
- v2: THREE.Vector3
- v3: THREE.Vector3
Returns CubicBezierCurve3
Overrides Curve.constructor
- Defined in node_modules/@types/three/src/extras/curves/CubicBezierCurve3.d.ts:5

Properties

arcLengthDivisions

arcLengthDivisions: number

This value determines the amount of divisions when calculating the cumulative segment lengths of a curve via .getLengths. To ensure precision when using methods like .getSpacedPoints, it is recommended to increase .arcLengthDivisions if the curve is very large.
