      property: TrackType,
      times: Float32Array,
      values: Float32Array,
      interpolation?: InterpolationType,
  ): KeyframeTrack

  Parameters

sampleQuaternion

• sampleQuaternion(time: number): Quaternion

  Samples this track at the given time. Valid only for tracks with property === "rotation". The returned Quaternion is owned scratch state, reused across calls -- copy it before the next call to sampleQuaternion/sampleVector on this same track if it must be retained.

  Parameters

  • time: number

  Returns Quaternion

sampleVector

• sampleVector(time: number): Vector3D

  Samples this track at the given time. Valid only for tracks with property === "translation" or property === "scale". The returned Vector3D is owned scratch state, reused across calls -- copy it before the next call to sampleQuaternion/sampleVector on this same track if it must be retained.

  Parameters

  • time: number

  Returns Vector3D
