OE2DPoint¶

class OE2DPoint

This class represents OE2DPoint that stores an x (horizontal), y (vertical) coordinate pair.

The coordinate system used in OEDepict TK has the origin (x=0.0, y=0.0) at the top/left with the x-axis pointing to the right and the y-axis pointing down. See Figure: 2D coordinate system.

Constructors¶

OE2DPoint()

Default constructor that initializes an OE2DPoint object with x = 0.0, y = 0.0 coordinates.

OE2DPoint(double x, double y)

Constructor that initializes an OE2DPoint object with the give x, y coordinates.

OE2DPoint(const OE2DPoint &rhs)

Copy constructor.

operator=¶

OE2DPoint &operator=(const OE2DPoint &rhs)

Assignment operator.

operator+¶

OE2DPoint operator+(const OE2DPoint &rhs) const

Addition operator: \((a_x, a_y) + (b_x, b_y) = (a_x + b_x, a_y + b_y)\)

operator-¶

OE2DPoint operator-(const OE2DPoint &rhs) const

Subtraction operator: \((a_x, a_y) - (b_x, b_y) = (a_x - b_x, a_y - b_y)\)

operator/¶

OE2DPoint operator/(double) const

Division operator: \((a_x, a_y) / D = (a_x / D, a_y / D)\)

operator *¶

OE2DPoint operator *(double) const

Multiplication operator: \((a_x, a_y) * D = (a_x * D, a_y * D)\)

operator+=¶

OE2DPoint &operator+=(const OE2DPoint &p)

Addition assignment operator.

operator-=¶

OE2DPoint &operator-=(const OE2DPoint &p)

Subtraction assignment operator.

operator/=¶

OE2DPoint &operator/=(double)

Division assignment operator.

operator*=¶

OE2DPoint &operator *=(double)

Multiplication assignment operator.
