Detailed Description

To store and treat a circular figure.

Constructor & Destructor Documentation

Constructor.

Parameters

[in]	c	Coordinates of center of circle
[in]	r	Radius
[in]	code	Code to assign to the generated domain [Default: 1]

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

virtual

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

The computed distance is negative if p lies in the disk, positive if it is outside, and 0 on the circle

Parameters

[in] p Point<double> instance

Reimplemented from Figure.

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

Operator +=.

Translate circle by a vector a

Circle& operator+= ( real_t a )

Operator *=.

Scale circle by a factor a
