Detailed Description

Point.

This class represents a point in 2D with x- and y-coordinates and an additional pointer to an associated triangle.

Constructor & Destructor Documentation

◆ Point2() [1/2]

GEOM_FADE25D::Point2::Point2	(	const double	x_,
		const double	y_,
		const double	z_
	)

inline

Constructor.

Parameters

x_	x-coordinate
y_	y-coordinate
z_	z-coordinate

◆ Point2() [2/2]

GEOM_FADE25D::Point2::Point2 ( const Point2 & p_ )

inline

Copy constructor.

Create a point as a copy of p_. The associated triangle pointer is initialized to NULL

Member Function Documentation

◆ getCustomIndex()

int GEOM_FADE25D::Point2::getCustomIndex ( ) const

inline

Get the custom index.

Returns: the custom index.

Note: The custom index defaults to -1. It is not the index of the point in the triangulation (such an index does not exist) but an arbitrary value which can be set by the user.

See also: void setCustomIndex(int customIndex_); A best practices example that deals with indices: http://www.geom.at/runtime/

◆ getIncidentTriangle()

Triangle2* GEOM_FADE25D::Point2::getIncidentTriangle ( ) const

inline

Get the associated triangle.

Returns: the associated triangle

◆ operator!=()

bool GEOM_FADE25D::Point2::operator!= ( const Point2 & p ) const

inline

Inequality operator.

Compares the x and y coordinates

Note: Although a point has a z-coordinate in the 2.5D version only x and y a compared by this method

◆ operator<()

bool GEOM_FADE25D::Point2::operator< ( const Point2 & p ) const

inline

Less than operator.

Compares the x and y coordinates

Note: Although a point has a z-coordinate in the 2.5D version only x and y a compared by this method

◆ operator==()

bool GEOM_FADE25D::Point2::operator== ( const Point2 & p ) const

inline

Equality operator.

Compares the x and y coordinates

Note: Although a point has a z-coordinate in the 2.5D version only x and y a compared by this method

◆ operator>()

bool GEOM_FADE25D::Point2::operator> ( const Point2 & p ) const

inline

Greater than operator.

Compares the x and y coordinates

Note: Although a point has a z-coordinate in the 2.5D version only x and y a compared by this method

◆ samePoint()

bool GEOM_FADE25D::Point2::samePoint ( const Point2 & p ) const

inline

Equality operator.

Compares the x,y,z coordinates while operator==() compares only x,y

◆ set() [1/2]

void GEOM_FADE25D::Point2::set	(	const double	x_,
		const double	y_,
		const double	z_,
		int	customIndex_
	)

inline

Set the coordinates.

Internal method

Parameters

x_	x-coordinate
y_	y-coordinate
z_	z-coordinate
customIndex_	Arbitrary index, use -1 if not required

◆ set() [2/2]

void GEOM_FADE25D::Point2::set ( const Point2 & pnt )

inline

Set the coordiantes.

Parameters

pnt	is the point whose coordinates are assigned to the current point

◆ setCoords()

void GEOM_FADE25D::Point2::setCoords	(	const double	x_,
		const double	y_,
		const double	z_
	)

inline

Set the coordinates.

Internal method

Parameters

x_	x-coordinate
y_	y-coordinate
z_	z-coordinate

Note: Does not adapt customIndex and pAssociatedTriangle.

◆ setCustomIndex()

void GEOM_FADE25D::Point2::setCustomIndex ( int customIndex_ )

inline

Set a custom index.

An arbitrary index can be assigned to a point. Use getCustomIndex() to retrieve it later.

Note: This method is provided for the users' convenience. It has nothing to do with the internal data structures of Fade 2D and using this method is optional. By default this index is -1.

See also: int getCustomIndex(); A best practices example that deals with indices: http://www.geom.at/runtime/

◆ setHeight()

void GEOM_FADE25D::Point2::setHeight ( double z )

inline

Set the z-coordinate.

Allows to exchange the z-coordinate

◆ setIncidentTriangle()

void GEOM_FADE25D::Point2::setIncidentTriangle ( Triangle2 * pT )

inline

Associate a triangle with the point.

Parameters

pT	will be associated with the triangle

◆ x()

double GEOM_FADE25D::Point2::x ( ) const

inline

Get the x-coordinate.

Returns: the x-coordinate

◆ xy()

void GEOM_FADE25D::Point2::xy	(	double &	x_,
		double &	y_
	)		const

inline

Get the x- and y-coordinate.

Parameters

x_	x-coordinate
y_	y-coordinate

◆ xyz()

void GEOM_FADE25D::Point2::xyz	(	double &	x_,
		double &	y_,
		double &	z_
	)		const

inline

Get the x-, y- and z-coordinate.

Parameters

x_	x-coordinate
y_	y-coordinate
z_	z-coordinate

◆ y()

double GEOM_FADE25D::Point2::y ( ) const

inline

Get the y-coordinate.

Returns: the y-coordinate

◆ z()

double GEOM_FADE25D::Point2::z ( ) const

inline

Get the z-coordinate.

Returns: the z-coordinate
