詳解

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.

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
rlbPlanar MGRLBRep to rotate.
slRotation axis. This is treated as infinite one, even if it is not.
angleRotation 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
rlbrepSweep crv.
uvecSweep Direction.
start_distdistance to start edge.
end_distdistance to end edge.
MGRSBRep::MGRSBRep ( const MGRSBRep old,
const MGKnotVector ut,
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
oldOriginal B-Rep.
utknot vector of u-direction
vtknot vector of v-direction
errorError 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
brepOriginal SBRep. This can be ordinary SBRep, or homogeneous form of MGRSBRep. When homogeneous form, the last space dimension elements are weights.
homogeneoustrue(non zero): homogeneous form, false(zero):ordinary SBRep.
MGRSBRep::MGRSBRep ( const MGRSBRep old,
const MGKnotArray uknots,
const MGKnotArray vknots 
)

uknotsKnots to add for u-direction
vknotsKnots 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
uvrangeu and v parameter range.
oldOriginal B-Rep.
multipleIndicates 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
dimNew space dimension.
sbrepOriginal Surface B-rep.
start1Destination order of new Surface.
start2Source 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).
