new AnimationInterpolantCubic(
    _times: Float32Array,
    _output: Float32Array,
    _elementSize: number,
    _result?: Float32Array,
): AnimationInterpolantCubic
Parameters
- _times: Float32Array
- _output: Float32Array
- _elementSize: number
- Optional_result: Float32Array
Returns AnimationInterpolantCubic

- Defined in Source/Core/AnimationNew/AnimationInterpolant.ts:102

Properties

elementSize

elementSize: number

elementStride

elementStride: number

The stride of the elements in the output array, which is the size of one element multiplied by 3 (inTangent, element, outTangent).

output: Float32Array

result

result: Float32Array

Methods

evaluate

evaluate(_t: number): Float32Array
Evaluates the interpolant at a given time.
Parameters
- _t: number
Returns Float32Array
Inherited from AnimationInterpolant.evaluate
- Defined in Source/Core/AnimationNew/AnimationInterpolant.ts:23

interpolate

interpolate(_i1: number, _t0: number, _t: number, _t1: number): Float32Array
Interpolates between the input/output buffer segment [_i1 - 1, _i1].
Parameters
- _i1: number
  The index of the right-hand keyframe.
- _t0: number
  The left-hand input value. input[_i1 - 1]
- _t: number
  The value to interpolate at. Between _t0 and _t1.
- _t1: number
  The right-hand input value. input[_i1]
Returns Float32Array
Overrides AnimationInterpolant.interpolate
- Defined in Source/Core/AnimationNew/AnimationInterpolant.ts:107
