Defines Surface B-Representation of rational form.

This NURBS is of homogeneous form, i.e., B-Coefficients have weight included values. When usual(non-homogeneous) NURBS form is (xij, yij, zij, wij) , MGRSBRep form is (xij*wij, yij*wij, zij*wij, wij) for i=0,..., m-1, and j=0,..., n-1.

構築子と解体子

MGRSBRep::MGRSBRep ( )

inline

Default constructor(dummy surface brep).

		int	homogeneous = 1
	)

tu	knot vector of u-direction
tv	knot vector of v-direction
homogeneous	true(non zero): homogeneous form, false(zero):ordinary SBRep.

		const MGKnotVector &	tv
	)

tu	knot vector of u-direction
tv	knot vector of v-direction

MGRSBRep::MGRSBRep	(	const MGRLBRep &	rlb,
		const MGStraight &	sl,
		double	angle
	)

Construct surface of revolution, given planar MGRLBRep and rotation axis sl. Parameterization of the surface is: u=const parameter line generates given rlb(when u=0.). v=const parameter line generates a circle whose center is sl.

引数

rlb	Planar MGRLBRep to rotate.
sl	Rotation axis. This is treated as infinite one, even if it is not.
angle	Rotation angle in radian, -2*pai<=angle<=2*pai, If angle is positive, circle is anti-clockwise around direction Vector N of sl. If negative, circle is clockwise around N.

MGRSBRep::MGRSBRep	(	const MGRLBRep &	rlbrep,
		const MGUnit_vector &	uvec,
		double	start_dist,
		double	end_dist
	)

Construct MGRSBRep by sweep NURBS and sweep length. The sweep surface is defined as: rlbrep(say c(t)) is the rail and the straight line segments from C(t)+start_dist*uvec to C(t)+end_dist*uvec are the generatrix.

引数

rlbrep	Sweep crv.
uvec	Sweep Direction.
start_dist	distance to start edge.

MGRSBRep::MGRSBRep	(	const MGRSBRep &	old,

		const MGKnotVector &	vt,
		int &	error
	)

Approximate an original B-Rep by a new knot configuration. The new knot config must be inside the range of the original B-Rep parameter. However new knots may be coarse or fine. Error indicates the contructor is successful(=0) or not(!=0). When error!=0, the original old is copied to this.

引数

old	Original B-Rep.
ut	knot vector of u-direction
vt	knot vector of v-direction
error	Error flag. Error is detected only when ut(=2) or vt(=112) is illegal.

MGRSBRep::MGRSBRep ( const MGSBRep &  brep, int  homogeneous = 0  )

explicit

Convert from Non ratoinal form to Rational form. When homogeneous==true(non zero), brep is homogeneous form MGSBRep. When homogeneous==false(zero), brep is ordinary MGSBRep and will be converted to MGRSBRep. That is, weight=1 elements will be added to the last space dimension element. ***** This is the fundamental constructor when homogeneous==1. *****

引数

brep	Original SBRep. This can be ordinary SBRep, or homogeneous form of MGRSBRep. When homogeneous form, the last space dimension elements are weights.
homogeneous	true(non zero): homogeneous form, false(zero):ordinary SBRep.

MGRSBRep::MGRSBRep	(	const MGRSBRep &	old,
		const MGKnotArray &	uknots,
		const MGKnotArray &	vknots
	)

引数

old	Original B-Rep.
uknots	Knots to add for u-direction
vknots	Knots to add for v-direction.

MGRSBRep::MGRSBRep	(	const MGBox &	uvrange,
		const MGRSBRep &	old,
		int	multiple = 0
	)

Gets new NURBS Surface by computing a part of the original. New one is exactly the same as the original except that it is partial. If multiple==true(!=0), knot_u(i)=t1 and knot_u(n+i)=t2 for i=0,..., k-1 will be guaranteed. Here, n=bdim_u(), k=order_u(), t1=uvrange(0).low_point(), and t2=uvrange(0).high_point(). About knot_v(j), the same. Both u-range and v-range must be inside the range of old.

引数

uvrange	u and v parameter range.
old	Original B-Rep.
multiple	Indicates if start and end knot multiplicities are necessary. =0:unnecessary, !=0:necessary.

MGRSBRep::MGRSBRep	(	int	dim,
		const MGRSBRep &	sbrep,
		int	start1 = 0,
		int	start2 = 0
	)

Construct a Surface B-Rep by changing space dimension and ordering of coordinates.

引数

dim	New space dimension.
sbrep	Original Surface B-rep.
start1	Destination order of new Surface.
start2	Source order of original Surface.

MGRSBRep::MGRSBRep	(	const std::vector< const MGRLBRep * > &	vecPtrRibRLBReps,
		bool	direction_adjustment = true
	)

リブ曲線列から面を作成する 作成する面のノットベクトルはリブ曲線の向きをu,リブ列方向をvとする This constructor only generates MGSBRep even if curves are MGRLBRep of the same knot configuration. To avoid this, use createSurfaceFromRibs() that generates MGRSBRep when curves are MGRLBRep of the same knot configuration. Let v0=start parameter value, v1=terminate parameter value along v, then v=v0 const parameter line is curves[0], and v=v1 const parameter line is curves[n-1], where n=curves.size(). n must be greater or equal to 2. When n==2, the surface is a ruled surface(that is, this->order_u() is 2).

If MGRLBRep's in vecPtrRibRLBReps may have different knot configurations, use the global function createSurfaceFromRibs(declared in MGSBRep.h).
