	)

Constructor.

		std::vector< MGBoundary * > &	boundaries,
		MGCell *	binder
	)

Fundamental constructor. Construct a face from geometry of manifold dimension 2 and the boundaries. The constructor takes the ownership of geo and MGBoundary in boundaries. boundaries must be loops.

MGFace::MGFace ( const MGSurface & surf )

inline

Face of whole surface of no boundary.

MGFace::MGFace ( const MGFSurface & surf )

Conversion constructor from MGFSurface to MGFace.

MGFace::MGFace ( MGSurface * surf )

Face of whole surface of no boundary. Ownership of surf is transfered to the face. (that is surf must be a newed object.)

MGFace::MGFace	(	const MGSurface &	surf,
		const std::vector< MGBoundary * > &	boundaries
	)

Construct a face by copying boundaries(only parameter rep of the boundary) from argument boundaries. Second form is to input a newed surface. The constructor takes the ownership of the surf.

関数詳解

void MGFace::add_boundary ( MGLoop * nloop )

Returned is the number of boudaries after appending. bound must be a newed MGLoop, and the ownership is transfered to this. *** append_boundary does not check validity with other loops (e.x. already existed loops will be outside the new boudanry bound). If the validity check is necessary, use add_boudanry().

		int *	order = `0`,
		double *	range = `0`

Rebuild this face. Rebuild means: 1) Rebuild the base surface. 2) Rebuild the parameter edges. 3) Rebuild the binder edges from the rebuilt parameter edges. This rebuild does not change the number of edges. All of the old edges does exist after the rebuild. Base surface rebuild is done only when the base surface is MGSBRep, or MGRSBRep.

引数

how_rebuild	intdicates how rebuild be done. =0: no base surface approximation(only parameter change) =1: If base surface is MGRSBRep, reconstruct it with new knot configuration again as rational spline(MGRSBRep). If MGSBRep, reconstruct with new knot configuration as MGSBRep. =2: approximated by non-rational spline(MGSBRep) with new knot configuration, even base surface is MGRSBRep. If the base surface is MGSBRep, same as =1.
parameter_normalization	Indicates how the parameter normalization be done: =0: no surface parameter normalization. =1: normalize to u_range=(0., 1.), and v_range=(0.,1.); =2: normalize to make the average length of the 1st deriv along u and v of the base surface is as equal to 1. as possible. =3: Specify parameter range in range[4].
tol	tolerance allowed for the approximation. When tol<=0., MGTolerance::line_zero() will be employed.
order	order of the new MGSBRep, >=4 is recomended. order[0]:u-order, [1]:v-order. When how_rebuild!=2, order is not used. When order=0 is input, order[0]=order[1]=4 are assumed.
range	valid only when parameter_normalization=3, and range[]={umin, umax, vmin, vmax}. When parameter_normalization=3 and range=0, parameter_normalization=2 is assumed.

When angle2 is angleBase, all the data will lie on the straight of from origin to (cos(angleBase), sin(angleBase)). angle1-angleBase must be >MGTolerance::angle_zero().

引数

int MGFace::trim ( const MGCurve & pcrv )

Trim the face giving parameter curve and world curve of a curve on the face. crv has a direction. That is, when this face is divided into two faces, left part face of the crv is the face selected.
