| const Vector3D< T > lass::prim::Vector3D< T >::normal | ( | ) | const |
return a unit vector with same direction/sense as this vector.
The normalized vector of X is a vector in the same direction but with norm (length) 1. It is denoted X^ and given by X^ = X / |X|, http://mathworld.wolfram.com/NormalizedVector.html.
