API Reference > geometry-core > Serialization > BSplineCurve3dH > getSaturatedBezierSpan3dOr3dH getSaturatedBezierSpan3dOr3dH Method Return a BezierCurveBase for this curve. Because BSplineCurve3dH is homogeneous, the returned BezierCurveBase is always homogeneous. getSaturatedBezierSpan3dOr3dH(spanIndex: number, _prefer3dH: boolean, result?: BezierCurveBase): undefined | BezierCurveBase Parameter Type Description spanIndex number _prefer3dH boolean result BezierCurveBase optional reusable curve. This will only be reused if it is a BezierCurve3dH with matching order. Returns - undefined | BezierCurveBase Defined in bspline/BSplineCurve3dH.ts Line 411 Last Updated: 11 June, 2024
