create MethodStatic

Create a bspline with given knots.

• The poles have several variants:

  • Float64Array(4 * numPoles) in blocks of [wx,xy,wz,w]
  • Point4d[numPoles]
  • Point3d[], with implied unit weight to be added.
  • {xyz: Float64Array(3 * numPoles), weights: Float64Array (numPoles)}

• Two count conditions are recognized:

** 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.

create(controlPointData: Point3d[] | Float64Array | Point4d[] | { weights: Float64Array, xyz: Float64Array }, knotArray: number[] | Float64Array, order: number): undefined | BSplineCurve3dH

Returns - undefined | BSplineCurve3dH
