詳解

Is to represent a Loop's point.

This is represented as (l, i, t), where l is loop pointer, i is the edge's iterator in the loop, and t is the parameter value of the curve of the pcell(edge).

構築子と解体子

MGLEPoint::MGLEPoint ( )

inline

MGLEPoint::MGLEPoint ( MGComplex::const_pcellItr  i, double  t  )

inline

引数

i	Loop's edge iterator.
t	Parameter value of i-th pcell curve.

MGLEPoint::MGLEPoint	(	const MGLoop &	lp,
		int	i,
		double	t
	)

Construct from the loop, edge number, and the edge's parameter value.

引数

lp	The target loop.
i	Edge number.
t	Parameter value of the edge i.

MGLEPoint::MGLEPoint

(

const MGLCisect &

lci

)

Conversion constructor from MGLCisect.

MGLEPoint::MGLEPoint	(	const MGLoop &	loop1,
		const MGLEPoint &	lep,
		const MGLoop &	loop2
	)

convert loop1's MGLEPoint lep to loop2's MGLEPoint. loop2 must be a copy of loop1.

引数

loop1	Loop 1.
lep	Parameter value of i-th pcell curve of loop1.
loop2	Loop2.

関数詳解

const MGEdge* MGLEPoint::edge

(

)

const

Obtain the edge pointer.

int MGLEPoint::edge_num

(

)

const

return loop's edge number.

MGEdge* MGLEPoint::edge_to_update

(

)

const

MGLEPoint MGLEPoint::end_of_pre_edge

(

)

const

bool MGLEPoint::equal_edge ( const MGLEPoint &  le2 ) const

inline

Test if two LEPoints are of the same edge.

bool MGLEPoint::equal_position

(

const MGLEPoint &

le2

)

const

Test if two LEPoints are of the same position.

bool MGLEPoint::equal_position

(

const MGPosition &

P

)

const

Test if this is the same position as P.

MGVector MGLEPoint::eval

(

int

nderi = 0

)

const

Evaluation of the loop at the LEPoint. When nderi=0, get the positional data(a parameter (u,v) of the surface) at the point.

MGVector MGLEPoint::eval_star

(

int

nderi = 0

)

const

Evaluation of the star curves of the loop at the point t. When nderi=0, get a position of the surface at the boundary point. The star curve is SurfCurve(face's surface, loop's curve). (The star curve has the same world coordinate with the binder curve's, but their direction may be opposite. The star curve has always the same direction as the loop.)

MGUnit_vector MGLEPoint::inner_vector

(

)

const

Compute a vector at the MGLEPoint point that goes inside the face and perpendicular to the boundary loop.

bool MGLEPoint::is_Edge_end_point

(

)

const

test if this is the end point of the loop.

bool MGLEPoint::is_Edge_start_point

(

)

const

test if this is the start point of the loop.

bool MGLEPoint::is_end_point

(

)

const

test if this is the end point of the loop.

bool MGLEPoint::is_start_point

(

)

const

test if this is the start point of the loop.

MGComplex::const_pcellItr MGLEPoint::iterator ( ) const

inline

Return the iterator of the edge.

const MGLoop* MGLEPoint::loop

(

)

const

Get loop pointer.

bool MGLEPoint::operator!= ( const MGLEPoint &  lp ) const

const MGLEPoint &

lp

const

double MGLEPoint::param ( ) const

inline

Return edge's curve parameter value.

void MGLEPoint::set	(	MGComplex::const_pcellItr	i,
		double	t
	)

Set iteraror of the edge and parameter value of the edge.

引数

i	Iterator of the edge.
t	parameter of the edge.
