Function Documentation

RayAABox() [1/2]

JPH_INLINE float RayAABox	(	Vec3Arg	inOrigin,
		const RayInvDirection &	inInvDirection,
		Vec3Arg	inBoundsMin,
		Vec3Arg	inBoundsMax
	)

Intersect AABB with ray, returns minimal distance along ray or FLT_MAX if no hit Note: Can return negative value if ray starts in box

RayAABox() [2/2]

JPH_INLINE void RayAABox	(	Vec3Arg	inOrigin,
		const RayInvDirection &	inInvDirection,
		Vec3Arg	inBoundsMin,
		Vec3Arg	inBoundsMax,
		float &	outMin,
		float &	outMax
	)

Intersect AABB with ray, returns minimal and maximal distance along ray or FLT_MAX, -FLT_MAX if no hit Note: Can return negative value for outMin if ray starts in box

RayAABox4()

JPH_INLINE Vec4 RayAABox4	(	Vec3Arg	inOrigin,
		const RayInvDirection &	inInvDirection,
		Vec4Arg	inBoundsMinX,
		Vec4Arg	inBoundsMinY,
		Vec4Arg	inBoundsMinZ,
		Vec4Arg	inBoundsMaxX,
		Vec4Arg	inBoundsMaxY,
		Vec4Arg	inBoundsMaxZ
	)

Intersect 4 AABBs with ray, returns minimal distance along ray or FLT_MAX if no hit Note: Can return negative value if ray starts in box

RayAABoxHits() [1/2]

JPH_INLINE bool RayAABoxHits	(	Vec3Arg	inOrigin,
		const RayInvDirection &	inInvDirection,
		Vec3Arg	inBoundsMin,
		Vec3Arg	inBoundsMax,
		float	inClosest
	)

Intersect AABB with ray, returns true if there is a hit closer than inClosest.

RayAABoxHits() [2/2]

JPH_INLINE bool RayAABoxHits	(	Vec3Arg	inOrigin,
		Vec3Arg	inDirection,
		Vec3Arg	inBoundsMin,
		Vec3Arg	inBoundsMax
	)

Intersect AABB with ray without hit fraction, based on separating axis test
