Detailed Description

Edge.

An edge is a curve with direction.
Direction of a curve MbCurve3D is rigidly connected with direction of increasing of its parameter. In contrast to a curve an edge may be directed either in the direction of increase of parameter or in the direction of decrease of parameter. An edge always starts and ends at some vertex MbVertex.

◆ Transform()

void MbEdge::Transform	(	const MbMatrix3D &	matr,
		MbRegTransform *	iReg = `nullptr`
	)

overridevirtual

Transform according to the matrix.

Transformation of an object according to the matrix. This object can be contained as pointer in several other objects for transformations. Registrar is used to prevent multiple transformation of this object. When transforming the object with registrator, the existence of the object inside the registrator is verified. If such object is absent, it is stored to the registrator and transformed, otherwise, a transformation of the object is not performed.

Parameters

[in]	matr	- A transformation matrix.
[in]	iReg	- Registrator.

Implements MbTopologyItem.

◆ Move()

void MbEdge::Move	(	const MbVector3D &	to,
		MbRegTransform *	iReg = `nullptr`
	)

overridevirtual

Move along a vector.

Move an object along a vector. When transforming the object with registrator, the existence of the object inside the registrator is verified. If such object is absent, it is stored to the registrator and transformed, otherwise, a transformation of the object is not performed.

Parameters

[in]	to	- Translation vector.
[in]	iReg	- Registrator.

Implements MbTopologyItem.

◆ Rotate()

void MbEdge::Rotate	(	const MbAxis3D &	axis,
		double	angle,
		MbRegTransform *	iReg = `nullptr`
	)

overridevirtual

Rotate around an axis.

Rotate an object at a given angle around an axis. When transforming the object with registrator, the existence of the object inside the registrator is verified. If such object is absent, it is stored to the registrator and transformed, otherwise, a transformation of the object is not performed.

Parameters

[in]	axis	- Rotation axis.
[in]	angle	- The rotation angle.
[in]	iReg	- Registrator.
