createFromPoints(
    positions: Vector3[],
    closed?: boolean,
    tension?: number,
): SplineContainer
Creates a SplineContainer from an array of points.
Parameters
- positions: Vector3[]
  The positions of the knots.
- closed: boolean = false
  Whether the spline is closed (the last knot connects to the first).
- tension: number = .75
  The tension of the spline. 0 is no tension, 1 is high tension (straight lines between knots). Default is 0.75.
Returns SplineContainer
The created SplineContainer component - add it to an Object3D to use it.
