Parameters
- OptionalisInternalConstructor: boolean
Returns AnimationUtility
Overrides FrameworkObject.constructor

Methods

`Static`calculateRange

calculateRange(curves): AnimationCurveRange
Calculates the total range covered by a set of curves.
Parameters
- curves: AnimationCurve[]
  Curves to calculate range for.
Returns AnimationCurveRange

`Static`combineCurve2D

combineCurve2D(curveComponents): Vector2Curve
Combines two single component curves into a Vector2 curve.
Parameters
- curveComponents: AnimationCurve[]
Returns Vector2Curve

`Static`combineCurve3D

combineCurve3D(curveComponents): Vector3Curve
Combines three single component curves into a Vector3 curve.
Parameters
- curveComponents: AnimationCurve[]
Returns Vector3Curve

`Static`eulerToQuaternionCurve

eulerToQuaternionCurve(eulerCurve, order?): QuaternionCurve
Converts a curve in euler angles (in degrees) into a curve using quaternions.
Parameters
- eulerCurve: Vector3Curve
- Optionalorder: EnumValue<EulerAngleOrder, number>
Returns QuaternionCurve

`Static`quaternionToEulerCurveYXZ

quaternionToEulerCurveYXZ(quatCurve): Vector3Curve
Converts a curve in quaternions into a curve using euler angles (in degrees).
Parameters
- quatCurve: QuaternionCurve
Returns Vector3Curve

`Static`splitCurve2D

splitCurve2D(compoundCurve): AnimationCurve[]
Splits a Vector2 curve into two individual curves, one for each component.
Parameters
- compoundCurve: Vector2Curve
Returns AnimationCurve[]

`Static`splitCurve3D

splitCurve3D(compoundCurve): AnimationCurve[]
Splits a Vector3 curve into three individual curves, one for each component.
Parameters
- compoundCurve: Vector3Curve
Returns AnimationCurve[]

`Static`transformCurves

transformCurves(transform, translationCurve, rotationCurve, scaleCurve): boolean
Given a 3D transform, it will decompose it and modifies the transform curves (translation, rotation, scale) appropriately to include the transform.
Parameters
- transform: Immutable<Matrix4>
- translationCurve: Vector3Curve
- rotationCurve: QuaternionCurve
- scaleCurve: Vector3Curve
Returns boolean
True if the operation was performed, else false (one of the curves is invalid).
