A 3D sphere

Member Function Documentation

◆ circumscribe()

template<class T >
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.

◆ intersect()

template<class T >
ATOMSMATH_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]lThe line
[out]intersectionThe point of intersection
Returns
True if the sphere and line intersect, false if they do not.

◆ intersectT()

template<class T >
ATOMSMATH_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]lThe line
[out]tThe parameter of the line at the intersection point
Returns
True if the sphere and line intersect, false if they do not.
