FindIntersection() [1/2]

template<typename RealType >

static bool UE::Geometry::TIntrRay3AxisAlignedBox3< RealType >::FindIntersection ( const TRay< RealType > &  Ray, const TAxisAlignedBox3< RealType > &  Box, RealType &  RayParamOut  )

inlinestatic

Find intersection of ray with AABB and returns ray T-value of intersection point (or TNumericLimits::Max() on miss)

Parameters

Ray	query ray
Box	query box
RayParamOut	ray intersect T-value, or TNumericLimits::Max()

Returns

true if ray intersects box

FindIntersection() [2/2]

template<typename RealType >

static bool UE::Geometry::TIntrRay3AxisAlignedBox3< RealType >::FindIntersection ( const TVector< RealType > &  Origin, const TVector< RealType > &  Direction, const TAxisAlignedBox3< RealType > &  Box, RealType &  RayParamOut  )

inlinestatic

Find intersection of ray with AABB and returns ray T-value of intersection point (or TNumericLimits::Max() on miss)

Parameters

Origin	query ray origin
Direction	query ray direction
Box	query box
RayParamOut	ray intersect T-value, or TNumericLimits::Max()

Returns

true if ray intersects box

TestIntersection()

template<typename RealType >

static bool UE::Geometry::TIntrRay3AxisAlignedBox3< RealType >::TestIntersection ( const TRay< RealType > &  Ray, const TAxisAlignedBox3< RealType > &  Box, RealType  ExpandExtents = 0  )

inlinestatic

Test if ray intersects box

Parameters

Ray	query ray
Box	query box
ExpandExtents	box is expanded by this amount in each direction, useful for dealing with float imprecision

Returns

true if ray intersects box
