Constructor & Destructor Documentation

MpLoop()

MpLoop::MpLoop	(	MpEdge *	initEdge,
		int	m
	)

Constructor.

Constructor by edge and the direction of construction.

Parameters

[in]	initEdge	- Edge.
[in]	m	- Direction of loop construction: if m > 0 - the loop is constructed counterclockwise, if m < 0 - clockwise.

Member Function Documentation

GetEdge() [1/2]

MpEdge* MpLoop::GetEdge ( ptrdiff_t  index ) const

inline

Edge by index.

Edge by its index. Without check for index correctness.

Parameters

[in]

index

- An edge index.

GetEdge() [2/2]

MpEdge*& MpLoop::GetEdge ( ptrdiff_t  index )

inline

Edge by index to change.

Edge by its index to change. Without check for index correctness.

Parameters

[in]

index

- An edge index.

DeleteEdge()

void MpLoop::DeleteEdge ( ptrdiff_t  index )

inline

Delete an edge by index.

Delete an edge by its index. Without check for index correctness.

Parameters

[in]

index

- An edge index.

SetMode()

void MpLoop::SetMode ( int  m )

inline

Set the traverse direction.

Set the direction of traversal of the loop.

Parameters

[in]

m

- The traversal direction. Has a value of sign of number m: if m > 0, then traversal is counterclockwise, if m < 0, then it is clockwise.

Transform()

void MpLoop::Transform

(

const MbMatrix &

matr

)

Transformation.

Parameters

[in]

to

- Movement vector.

Rotate()

void MpLoop::Rotate	(	const MbCartPoint &	pnt,
		const MbDirection &	angle
	)

Rotate.

Rotate at angle around a point.

Parameters

[in]	pnt	- A point is a rotation center.
[in]	angle	- A two-dimensional normalized vector determining the rotation angle.
