Detailed Description

Sphere class.

Spheres are represented by a centerpoint and a radius. A point belongs to the sphere if , where and represent the sphere centerpoint and radius, respectively.

Constructor & Destructor Documentation

mt::Sphere3::Sphere3 ( const Point3 &  center, const Scalar &  radius  )

inline

Centerpoint and radius constructor. Since the radius must be a positive value, its absolute value is taken (just in case) without issuing warnings or errors.

Member Function Documentation

Scalar mt::Sphere3::distance ( const Point3 &  p ) const

inline

Signed distance from point p to current sphere.

Positive distance -> Point lies outside the sphere. Null distance -> Point is contained in sphere. Negative distance -> Point lies inside the sphere.

void mt::Sphere3::setRadius ( const Scalar &  radius )

inline

Sets sphere radius. Since the radius must be a positive value, its absolute value is taken (just in case) without issuing warnings or errors.

void mt::Sphere3::setValue ( const Point3 &  center, const Scalar &  radius  )

inline

Sets sphere parameters. Since the radius must be a positive value, its absolute value is taken (just in case) without issuing warnings or errors.
