API Reference > geometry-core > Bspline > 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): BezierCurveBase | undefined 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 - BezierCurveBase | undefined Defined in core/geometry/src/bspline/BSplineCurve3dH.ts Line 332 Last Updated: 13 June, 2024
