class Sphere : public Surface 

A sphere around point _center with radius _radius.

Public Functions

Sphere(const Vector3d &center, double radius)

virtual double distance(const Vector3d &point) const

Returns the distance of a point to the surface. Negative on the one side, positive on the other. For closed surfaces it is negative on the inside.

Parameters:: point – vector corresponding to the point to which compute the distance

virtual Vector3d normal(const Vector3d &point) const

Returns the normal to the surface at a point. Negative on the one side, positive on the other. For closed surfaces it is negative on the inside.

Parameters:: point – vector corresponding to the point to which compute the normal vector

virtual std::string getDescription() const

inline size_t addReference() const

inline size_t removeReference() const

inline int removeReferenceNoDelete() const

inline size_t getReferenceCount() const
