成员函数说明

AddHole()

static TopoShape SurfaceBuilder.AddHole ( TopoShape face, TopoShape wireOfHole )

static

在曲面上挖孔

参数

face	面
wireOfHole	孔轮廓线

返回

AddHoles()

static TopoShape SurfaceBuilder.AddHoles ( TopoShape face, TopoShapeList wiresOfHoles )

static

曲面上挖多个孔

参数

face	面
wiresOfHoles	孔轮廓线

返回

MakeBSplineSurface() [1/2]

static TopoShape SurfaceBuilder.MakeBSplineSurface ( GPntList2 arr2Points, DoubleList2 arr2Weights, DoubleList uKnots, DoubleList vKnots, Uint32List uMults, Uint32List vMults, long uDegree, long vDegree, boolean uPeriodic, boolean vPeriodic )

static

Creates a B-spline surface from 2D control points and parameters

参数

arr2Points	2D array of control points arranged as [u][v], dimensions must match surface topology
arr2Weights	2D array of weights corresponding to control points. Empty creates non-rational surface
uKnots	Knot vector for U direction, must be non-decreasing
vKnots	Knot vector for V direction, must be non-decreasing
uMults	Multiplicities for U knots, length must match uKnots
vMults	Multiplicities for V knots, length must match vKnots
uDegree	Polynomial degree in U direction (≥1)
vDegree	Polynomial degree in V direction (≥1)
uPeriodic	True to create periodic surface in U direction
vPeriodic	True to create periodic surface in V direction

返回

TopoShapePtr Resulting B-spline surface or nullptr on error

Note: All rows in arr2Points must contain equal number of points. Periodic surfaces require
proper overlap of control points at boundaries according to degree.
