Constructor & Destructor Documentation

◆ TLookFromMatrix() [1/2]

template<typename T >
FORCEINLINE UE::Math::TLookFromMatrix< T >::TLookFromMatrix ( const TVector< T > & EyePosition,
const TVector< T > & LookDirection,
const TVector< T > & UpVector )

Creates a view matrix given an eye position, a direction to look in, and an up vector. Direction or up vectors need not be normalized. This does the same thing as FLookAtMatrix, except without completely destroying precision when position is large, Always use this instead of e.g., FLookAtMatrix(Pos, Pos + Dir,...);
