Detailed Description

To store and treat a sphere.

Constructor & Destructor Documentation

Constructor.

Parameters

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

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

virtual

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

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

Parameters

[in] p Point<double> instance

Reimplemented from Figure.

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

Operator +=.

Translate sphere by a vector a

Sphere& operator+= ( real_t a )

Operator *=.

Scale sphere by a factor a
