Detailed Description

template<typename T>
struct UE::Geometry::TLine3< T >

TLine3 is a three-dimensional infinite line. The line is stored in (Center,Direction) form.

Constructor & Destructor Documentation

◆ TLine3() [1/2]

template<typename T >
UE::Geometry::TLine3< T >::TLine3 ( )
inline

Construct default line along X axis

◆ TLine3() [2/2]

template<typename T >
UE::Geometry::TLine3< T >::TLine3 ( const TVector< T > &  OriginIn,
const TVector< T > &  DirectionIn 
)
inline

Construct line with given Origin and Direction

Member Function Documentation

◆ DistanceSquared()

template<typename T >
T UE::Geometry::TLine3< T >::DistanceSquared ( const TVector< T > &  QueryPoint) const
inline
Returns
smallest squared distance from line to QueryPoint

const TVector< T > &  Point1 
)
inlinestatic
Returns
line between two points

◆ NearestPoint()

template<typename T >
TVector< T > UE::Geometry::TLine3< T >::NearestPoint ( const TVector< T > &  QueryPoint) const
inline
Returns
nearest point on line to QueryPoint

◆ PointAt()

template<typename T >
TVector< T > UE::Geometry::TLine3< T >::PointAt ( T  LineParameter) const
inline
Returns
point on line at given line parameter value (distance along line from origin)

◆ Project()

template<typename T >
T UE::Geometry::TLine3< T >::Project ( const TVector< T > &  QueryPoint) const
inline
Returns
line parameter (ie distance from Origin) at nearest point on line to QueryPoint
