Detailed Description

To store and treat an ellipsoidal figure.

Constructor & Destructor Documentation

Ellipse ( )

Default constructor.

Constructs an ellipse with semimajor axis = 1, and semiminor axis = 1

Constructor with given ellipse data.

Parameters

[in]	c	Coordinates of center
[in]	a	Semimajor axis
[in]	b	Semiminor axis
[in]	code	Code to assign to the generated figure [Default: 1]

real_t getSignedDistance ( const Point< real_t > & p ) const

virtual

Return signed distance of a given point from the current ellipse.

The computed distance is negative if p lies in the ellipse, positive if it is outside, and 0 on its boundary

Parameters

[in] p Point<double> instance

Reimplemented from Figure.

Ellipse& operator+= ( Point< real_t > a )

Operator +=

Translate ellipse by a vector a

Parameters

[in] a Vector defining the translation

Ellipse& operator+= ( real_t a )

Operator *=

Scale ellipse by a factor a

Parameters

[in] a Scaling value
