Member Function Documentation

TVector2<T> NormalRight (   )  const [inline]

Returns normal N to this vector, such that DotProduct(*this, N) = 0. Parameters: def  - vector returned if the length of this vector is near zero Note: Projection of the resulting vector to the X axis will have the same sign that projection of this vector. If x = 0, then normal will be equal (1,0)
