Detailed Description

The Point2 class represents a 2D point with x- and y-coordinates.

Constructor & Destructor Documentation

◆ Point2() [1/3]

GEOM_FADE2D::Point2::Point2	(	const double	x_,
		const double	y_
	)

inline

Constructor for a 2D point. Initializes the customIndex to -1.

Parameters

x_,y_ The coordinates of the point

◆ Point2() [2/3]

GEOM_FADE2D::Point2::Point2 ( )

inline

Initializes the coordinates to -DBL_MAX, the associated Triangle2 to NULL, and the customIndex to -1.

◆ Point2() [3/3]

GEOM_FADE2D::Point2::Point2 ( const Point2 & p_ )

inline

Copy constructor. Copies the coordinates and the custom index.

Parameters

[in] p_ The point to be copied.

Member Function Documentation

◆ getCustomIndex()

int GEOM_FADE2D::Point2::getCustomIndex ( ) const

inline

Returns: The custom index of the Point2.

Note: The custom index defaults to -1. It is not related to the point's index in the triangulation (since such an index does not exist), but rather an arbitrary value that can be assigned by the user for associating the Point2 with their own data structures.

See also: void setCustomIndex(int customIndex_)

◆ getMaxAbs()

double GEOM_FADE2D::Point2::getMaxAbs ( ) const

inline

Get the maximum of the absolute values of the x- and y-coordinates.

Returns: The larger of the absolute values of x and y

◆ operator!=()

bool GEOM_FADE2D::Point2::operator!= ( const Point2 & p ) const

inline

This function checks if the current Point2 and p are different, based on the x and y coordinates.

Parameters

p	The point to compare with.

Returns: true if the points are different, false otherwise

◆ operator+()

Point2 GEOM_FADE2D::Point2::operator+ ( const Vector2 & vec ) const

inline

Adds a Vector2 vec to the current Point2 and returns the resulting Point2.

Parameters

vec	The vector to be added.

Returns: The resulting Point2

◆ operator-() [1/2]

Vector2 GEOM_FADE2D::Point2::operator- ( const Point2 & other ) const

inline

Creates a Vector2, pointing from Point2 other to the current Point2.

Parameters

other The other Point2.

Returns: The resulting Vector2 pointing from Point2 other to the current Point2.

◆ operator-() [2/2]

Point2 GEOM_FADE2D::Point2::operator- ( const Vector2 & vec ) const

inline

Subtracts a Vector2 from the Point2 and returns the resulting Point2.

Parameters

vec	The vector to be subtracted.

Returns: The resulting Point2

◆ operator<()

bool GEOM_FADE2D::Point2::operator< ( const Point2 & p ) const

inline

Less-than comparison, based on x and y coordinates.

Parameters

p	The Point2 to compare with

Returns: true if the current point is less, false otherwise

◆ operator=()

Point2& GEOM_FADE2D::Point2::operator= ( const Point2 & other )

inline

Assignment operator.

Parameters

other The point whose coordinates and the custom index are assigned

◆ operator==()

bool GEOM_FADE2D::Point2::operator== ( const Point2 & p ) const

inline

This function compares the current Point2 with another one based on the x and y coordinates.

Parameters

p	The point to compare with.

Returns: true if the points are equal (same x and y), false otherwise.

◆ operator>()

bool GEOM_FADE2D::Point2::operator> ( const Point2 & p ) const

inline

Greater-than comparison, based on x and y coordinates.

Parameters

p	The Point2 to compare with.

Returns: true if the current Point2 is greater, false otherwise.

◆ setCustomIndex()

void GEOM_FADE2D::Point2::setCustomIndex ( int customIndex_ )

inline

This method allows you to assign an arbitrary index to the Point2, which can be used to associate it with custom data structures in your software. To retrieve the index later, you can use the getCustomIndex() method.

Parameters

customIndex_ The custom index to be assigned to the Point2.

Note: This method is provided for the user's convenience to associate a Point2 with their own data structures. It is not related to the internal data structures of Fade 2D, and its usage is optional. By default, the customIndex is set to -1.

See also: int getCustomIndex()

◆ x()

double GEOM_FADE2D::Point2::x ( ) const

inline

Get the x-coordinate of the current Point2.

Returns: The x-coordinate

◆ xy()

void GEOM_FADE2D::Point2::xy	(	double &	x_,
		double &	y_
	)		const

inline

Retrieves the x- and y- coordinates of the current Point2.

Parameters

x_,y_ Used to return the coordinate values.

◆ y()

double GEOM_FADE2D::Point2::y ( ) const

inline

Get the y-coordinate of the current Point2.

Returns: The y-coordinate
