詳解

Defines End Condition of Surface B-Representation.

Class for MGSBRep constructor like: MGSBRep( ///BLG4SP...Derivative Inf. MGSBRepEndC& endc, ///end condition const MGNDDArray& utaui, ///Data point of u-direction of value const MGNDDArray& vtaui, ///Data point of v-direction of value const MGSPointSeq& value, ///Data point ordinate int &error); ///Error flag. Provides four perimeter end conditions and four corners end conditions. For a perimeter, four types of conditions can be applied: MGENDC_NO: no end cond(only positional data) MGENDC_1D: 1st deravative provided. MGENDC_2D: 2nd deravative provided. MGENDC_12D: both 1st and 2nd deravatives provided. When m_cond[0]=MGENDC_1D and m_cond[1]=MGENDC_1D, twist vector d2f/(du*dv) is necessary at the corner of u=max and v=min. Although users can provide the data, complete_corner_deriv computes the data from given data if not provided. At other corners or for other conditions, the same.

To construct MGSBRepEndC, first construct through void constructor. Then use set_1st(), set_2nd, set_11d(), set_12d(), set_21d(), or set_22d() to complete. Any of set_11d(), set_12d(), set_21d(), or set_22d() can be omitted. complete_corner_deriv will compute instead. This is done in SBRep constructor.

関数詳解

void MGSBRepEndC::complete_corner_deriv	(	const MGNDDArray &	utau,
		const MGNDDArray &	vtau
	)

Complete corner derivatives(twist vectors and higher order derivatives)

引数

utau	u-direction data point
vtau	v-direction data point

MGENDCOND MGSBRepEndC::cond ( int  i ) const

inline

Return i-th perimeter's condition. i=0, 2 are v=min and max u-parameter line. i=1, 3 are u=max and min v-parameter line.

const MGVector& MGSBRepEndC::deriv11 ( int  i ) const

inline

Return i-th corner's derivative inf. i=0:(u-min, v-min), =1:(u-max, v-min), =2:(u-max, v-max), =3:(u-min, v-max)

const MGVector& MGSBRepEndC::deriv12 ( int  i ) const

inline

const MGVector& MGSBRepEndC::deriv21 ( int  i ) const

inline

const MGVector& MGSBRepEndC::deriv22 ( int  i ) const

inline

const MGBPointSeq& MGSBRepEndC::first ( int  i ) const

inline

Return i-th perimeter's first and second derivatives.

void MGSBRepEndC::initialize

(

)

Initialize the instance. Will be set to the same as constructed by the void constructor.

MGSBRepEndC& MGSBRepEndC::operator=

const MGSBRepEndC &

ec

)

const MGBPointSeq& MGSBRepEndC::second ( int  i ) const

inline

void MGSBRepEndC::set_11d	(	int	i,
		const MGVector &	deriv
	)

Set m_11d[i] inf(d2f/(du*dv)) of i-th corner.

void MGSBRepEndC::set_12d	(	int	i,
		const MGVector &	deriv
	)

Set m_12d[i] inf(d3f/(du*dv**2)) of i-th corner.

void MGSBRepEndC::set_1st	(	int	i,
		const MGBPointSeq &	first_deriv
	)

Set 1st deriv of i-th perimeter and change condition type to MGENDC_1D or MGENDC_12D. For i=0 and 2, first_deriv=df/dv, for i=1 and 3 first_deriv=df/du 1st form is to copy first_deriv, and 2nd form is to transfer the ownership of the first_derivp to SBRepEndC. 2nd form is recommended since no copy takes place.

void MGSBRepEndC::set_1st	(	int	i,
		std::auto_ptr< MGBPointSeq > &	first_derivp
	)

void MGSBRepEndC::set_21d	(	int	i,
		const MGVector &	deriv
	)

Set m_21d[i] inf(d3f/(du**2*dv)) of i-th corner.

void MGSBRepEndC::set_22d	(	int	i,
		const MGVector &	deriv
	)

Set m_22d[i] inf(d4f/du**2*dv**2) of i-th corner.

void MGSBRepEndC::set_2nd	(	int	i,
		const MGBPointSeq &	second_deriv
	)

Set 2nd deriv of i-th perimeter and change condition type to MGENDC_2D or MGENDC_12D. For i=0 and 2, first_deriv=d2f/dv**2, for i=1 and 3 first_deriv=d2f/du**2 1st form is to copy second_deriv, and 2nd form is to transfer the ownership of the second_derivp to SBRepEndC. 2nd form is recommended since no copy takes place.

void MGSBRepEndC::set_2nd	(	int	i,
		std::auto_ptr< MGBPointSeq > &	second_derivp
	)
