API Reference > geometry-core > Bspline > BSplineSurface3dH > createGrid createGrid MethodStatic Create a bspline with given knots. Two count conditions are recognized in each direction: ** If poleArray.length + order == knotArray.length, the first and last are assumed to be the extraneous knots of classic clamping. ** If poleArray.length + order == knotArray.length + 2, the knots are in modern form. createGrid(xyzwGrid: number[][][], weightStyle: WeightStyle, orderU: number, knotArrayU: number[], orderV: number, knotArrayV: number[]): BSplineSurface3dH | undefined Parameter Type Description xyzwGrid number[][][] weightStyle WeightStyle orderU number knotArrayU number[] orderV number knotArrayV number[] Returns - BSplineSurface3dH | undefined Defined in core/geometry/src/bspline/BSplineSurface.ts Line 836 Last Updated: 13 June, 2024
