A 3D sphere

Definition at line 26 of file ImathSphere.h.

Constructor & Destructor Documentation

template<class T>

IMATH_HOSTDEVICE constexpr Sphere3< T >::Sphere3 ( )

inline

Default is center at (0,0,0) and radius of 0.

Definition at line 45 of file ImathSphere.h.

template<class T>

IMATH_HOSTDEVICE constexpr Sphere3< T >::Sphere3 ( const Vec3< T > &  c, T  r  )

inline

Initialize to a given center and radius.

Definition at line 48 of file ImathSphere.h.

Member Function Documentation

template<class T >

IMATH_HOSTDEVICE void Sphere3< T >::circumscribe ( const Box< Vec3< T >> &  box )

inline

Set the center and radius of the sphere so that it tightly encloses Box b.

Definition at line 98 of file ImathSphere.h.

template<class T >

IMATH_CONSTEXPR14 bool Sphere3< T >::intersect	(	const Line3< T > &	l,
		Vec3< T > &	intersection
	)		const

If the sphere and line l intersect, then compute the smallest t with t>=0 so that l(t) is a point on the sphere.

Parameters

[in]	l	The line
[out]	intersection	The point of intersection

Returns

True if the sphere and line intersect, false if they do not.

Definition at line 148 of file ImathSphere.h.

template<class T >

IMATH_HOSTDEVICE IMATH_CONSTEXPR14 bool Sphere3< T >::intersectT	(	const Line3< T > &	l,
		T &	t
	)		const

If the sphere and line l intersect, then compute the smallest t with t>=0 so that l(t) is a point on the sphere.

Parameters

[in]	l	The line
[out]	t	The parameter of the line at the intersection point

Returns

True if the sphere and line intersect, false if they do not.

Definition at line 106 of file ImathSphere.h.
