Function documentation

template<class T> template<std::size_t otherSize>
static Vector4<T> Magnum::Math::Vector4<T>::pad(const Vector<otherSize, T>& a, T xyz, T w) constexpr

Pad vector to four-component one.

If size of a is smaller than 4, it is padded from right with xyz for first three component and w for fourth component, otherwise it's cut.

template<class T>
Magnum::Math::Vector4<T>::Vector4(ZeroInitT = ZeroInit) constexpr noexcept

Default constructor.

\[ \boldsymbol v = \boldsymbol 0 \]

template<class T>
Magnum::Math::Vector4<T>::Vector4(T x, T y, T z, T w) constexpr noexcept

Constructor.

\[ \boldsymbol v = \begin{pmatrix} x \\ y \\ z \\ w \end{pmatrix} \]

template<class T>
Magnum::Math::Vector4<T>::Vector4(const Vector3<T>& xyz, T w) constexpr noexcept

Constructor.

\[ \boldsymbol v = \begin{pmatrix} v_x \\ v_y \\ v_z \\ w \end{pmatrix} \]

template<class T> template<class U>
Magnum::Math::Vector4<T>::Vector4(const Vector<4, U>& other) explicit constexpr noexcept

Construct vector from another of different type.

Performs only default casting on the values, no rounding or anything else. Example usage:

Vector<4, Float> floatingPoint(1.3f, 2.7f, -15.0f, 7.0f);
Vector<4, Byte> integral(floatingPoint);
// integral == {1, 2, -15, 7}
