Polygon on double data.

Polygon is an ordered set of points in space, sequential connection of these points produces polyline that approximates an object or part of an object.

Member Function Documentation

◆ Clone()

SPtr<MbPrimitive> MbExactPolygon3D::Clone ( MbRegDuplicate * iReg = nullptr ) const

overridevirtual

Create a copy of primitive.

Create a copy of primitive using the registrator. Registrator is used for preventing multiple copying of primitive contained in several simultaneously copied objects. It is allowed not to use the registrator while copying a single object or a set of disconnected objects. The registrator must be used to copy several correlated objects successively. Correlation is an existence of references to common primitives in objects. Then, while copying without using the registrator, one can get a set of copies which contains references to the different copies of a single included primitive, what leads to loss of connection between the copies.

Parameters

[in] iReg - Registrator.

Returns: The object copy.

Implements MbPrimitive.

◆ Transform()

void MbExactPolygon3D::Transform ( const MbMatrix3D & matr )

overridevirtual

Transform primitive according to the matrix.

Transform primitive according to the matrix using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to transformation.

Parameters

[in] matr - A transformation matrix.

Implements MbPrimitive.

◆ Move()

void MbExactPolygon3D::Move ( const MbVector3D & to )

overridevirtual

Move primitive along a vector.

Move primitive along the vector using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to moving.

Parameters

[in] to - Movement vector.

Implements MbPrimitive.

◆ Rotate()

void MbExactPolygon3D::Rotate	(	const MbAxis3D &	axis,
		double	angle
	)

overridevirtual

Rotate primitive about an axis by a given angle.

Rotate primitive about an axis by a given angle using the registrator. The registrator is used for preventing multiple transformation of primitive contained in several simultaneously transformed objects. The function can be used without the registrator to transform a single object. The registrator must be used to transform a set of interdependent objects to prevent repeated transformation of the nested primitives, since it is not ruled out that several objects from the set contain references to one or several common primitives subject to rotation.

Parameters

[in]	axis	- The rotation axis.
[in]	angle	- The rotation angle.

Implements MbPrimitive.

◆ IsPlanar()

bool MbExactPolygon3D::IsPlanar	(	MbPlacement3D &	plane,
		double	metricAccuracy = `Math::metricRegion`
	)		const

overridevirtual

Check whether all points of polygon lie on the same plane with the given metricAccuracy accuracy. if so, then initialize 'plane' plane.

Implements MbPolygon3D.
