rayBoxIntersect() [1/2]

template<typename T = float>

bool MR::rayBoxIntersect	(	const Box3< T > &	box,
		const Line3< T > &	line,
		T	t0,
		T	t1 )

#include <MRMesh/MRRayBoxIntersection.h>

finds intersection between the Ray and the Box, which must be valid

rayBoxIntersect() [2/2]

template<typename T = float>

bool MR::rayBoxIntersect	(	const Box3< T > &	box,
		const RayOrigin< T > &	rayOrigin,
		T &	t0,
		T &	t1,
		const IntersectionPrecomputes< T > &	prec )

#include <MRMesh/MRRayBoxIntersection.h>

CPU(X86_64) - AMD64 / Intel64 / x86_64 64-bit finds intersection between the Ray and the Box. The box must be valid, otherwise the result is undefined. Precomputed values could be useful for several calls with the same direction, see "An Efficient and Robust Ray-Box Intersection Algorithm" at https:/// people.csail.mit.edu/amy/papers/box-jgt.pdf
