Public Member Functions
bool	hit () const noexcept
	Whether the ray crosses the surface.

Public Attributes
HitStatus	m_status = HitStatus::Miss
	Whether the ray crosses the surface.
T	m_t = Math::Limits<T>::infinity()
	Distance along the ray: of the crossing for a hit, of the last point reached for an unresolved query, and infinity for a miss.
Vec3T< T >	m_point = Vec3T<T>::zeros()
	The point at m_t (for a hit or an unresolved query).
uint32_t	m_primitive = 0
	The finest element the shape can name at the crossing: the face of a mesh SDF, the deciding leaf of a tape (see Tape::closestPrimitive()), the member of a BVHUnion (its place in the union's storage), and 0 for any other shape.
Vec3T< T >	m_normal = Vec3T<T>::zeros()
	The outward unit normal at the crossing: from the shape's ray form, or the normalized gradient of its signed distance for a marched crossing.
bool	m_entering = false
	Whether the ray enters the object there (it was outside just before), rather than leaving it.
bool	m_exact = false
	Whether the crossing is exact (found by a ray form), rather than found to within RayOptions::m_tolerance by marching.
