Defines Tangent Plane Line B-Representation Class.

Tangent plane is a line b-representation of (unit)normal vector of tangent plane along a surface perimeter. MGSBRepVecTP has a vector of 4 newed object pointer ofMGLBRep representing the normal vetor B-rep along the 4 perimeter of surface. And regarding to their ownership MGSBRepVecTP acts just like std::auto_ptr. That is, all of the ownership will be transfered to the copied, or assigned object. See the copy oroperator=() below.

構築子と解体子

MGSBRepVecTP::MGSBRepVecTP ( )

inline

Default Constructor, will be set as no TPs' are specified.

MGSBRepVecTP::MGSBRepVecTP ( const MGSBRepVecTP & vectp2 )

Copy Constructor. all of the ownership of m_TP of tp2 will be transfered to this object.

MGSBRepVecTP::MGSBRepVecTP ( const MGSBRepTP & tp2 )

Conversion constructor from ordinary MGSBRepTP.

関数詳解

void MGSBRepVecTP::change_range	(	bool	along_u,
		double	t0,
		double	t1
	)

change the parameter range to (t0,t1).

引数

along_u	the objective range is along u parameter or v.
t0	target range, from t0,
t1	to t1.

void MGSBRepVecTP::change_range	(	bool	along_u,
		const MGInterval &	prange
	)

change the parameter range to prange.

引数

along_u	the objective range is along u parameter or v.
prange	target range.

bool MGSBRepVecTP::eval	(	int	i,
		double	t,
		MGVector &	normal
	)		const

evaluate TP at the perimeter i's parameter t. Function's return value is: true if t was inside the parameter range of a tangent plane of m_TP[i]. false if t was outside the parameter range of the m_TP[i] for all i.

引数

i	perimeter numeber.
t	parameter vaule of perimeter i.
normal	evaluated normal will be returned.

double MGSBRepVecTP::get_perimeters_max_cos	(	const MGPvector< MGLBRep > &	deris,
		double	taumax[4],
		double	cosmax[4]
	)		const

Compute the maximum (absolute) cos value of between vector deris[i](t) and vector this->TP(i)(t) for i=0,1,2,3, where t is a common parameter of the data point obtained from deris[i]'s knot vector. Function's return value is the max out of cosmax[.].

引数

deris	the size must be 4
taumax	parameter on which the maximum value attains will be stored
cosmax	the maximum value will be stored

double MGSBRepVecTP::get_perimeters_max_sin	(	const MGSurface &	srf,
		double	taumax[4],
		double	sinmax[4],
		bool *	eval = `0`
	)		const

Compute the maximum (absolute) sin value of between vector srf.normal(uv(t)) and vector this->TP(i)(t) for i=0,1,2,3, where perim[i] is the same as srf.perimeter_curve(i), and t is a common parameter of deris[i] and TP(i). Function's return value is the max out of sinmax[.].

引数

srf	surface which must corresponds to this object
taumax	parameters on which the maximum value attains will be stored.
sinmax	the maximum value will be stored.
eval	indicates perimeters to evalate if eval!=null When eval[i] is true, perimeter i is evaluated for 0<=i<=3.

MGSBRepVecTP& MGSBRepVecTP::operator= ( const MGSBRepVecTP & vectp2 )

Assignment. all of the ownership of m_TP of tp2 will be transfered to this object.

void MGSBRepVecTP::set_TP	(	int	i,
		MGPvector< MGLBRep > &	vectp,
		const MGInterval &	prange
	)

Set i-th perimeter's TP(copy version). vectp[i] must be newed objects, and all of the ownership will be transferer to this instance.

引数

i	perimeter numeber.
vectp	TP data.
prange	Whole perimeter's parameter range.

void MGSBRepVecTP::set_TP	(	int	i,
		std::vector< MGLBRep * > &	vectp,
		const MGInterval &	prange
	)

Set i-th perimeter's TP(std::vector version). vectp[i] must be newed objects, and all of the ownership will be transferer to this instance.

引数

i	perimeter number.
vectp	TP data.
prange	Whole perimeter's parameter range.

void MGSBRepVecTP::set_TP_null ( int i )

Set i-th perimeter's TP as a null, as an unspecified one.

bool MGSBRepVecTP::specified ( int i ) const

inline

Return true if at least one TP is specified at i-th perimeter. i=0, 2 are v=min and max u-parameter line. i=1, 3 are u=max and min v-parameter line.

const MGPvector<MGLBRep>& MGSBRepVecTP::vecTP ( int i ) const

inline

Return i-th perimeter's TP.
