TVec4


This template represents 4D vector.

You can find more information in comments below.

template<class TYPE>
union TVec4

    struct // As coordinates

    TYPE operator[](const size_t index) const; // Return element by index. Only 0, 1, 2 and 3 are accepted as indices. Used only when TVec4 object is a constant object
    TYPE &operator[](const size_t index); // Return element by index. Only 0, 1, 2 and 3 are accepted as indices
    explicit operator TPoint<TYPE>() const; // Convert to TPoint

Additionally following operators exists.

template<class TYPE>
bool operator==(const TVec4<TYPE> &a, const TVec4<TYPE> &b); // Check whether vectors are equal. Can be used for non-float data types only
template<class TYPE>
bool operator!=(const TVec4<TYPE> &a, const TVec4<TYPE> &b); // Check whether vectors aren't equal. Can be used for non-float data types only
template<class TYPE>
TVec4<TYPE> operator+(const TVec4<TYPE> &v, const TYPE val); // Add vector and scalar
template<class TYPE>
TVec4<TYPE> operator-(const TVec4<TYPE> &v, const TYPE val); // Subtract vector and scalar
template<class TYPE>
TVec4<TYPE> operator*(const TVec4<TYPE> &v, const TYPE val); // Multiply vector and scalar
template<class TYPE>
TVec4<TYPE> operator/(const TVec4<TYPE> &v, const TYPE val); // Divide vector and scalar
template<class TYPE>
TVec4<TYPE> operator+(const TYPE val, const TVec4<TYPE> &v); // Add scalar and vector
template<class TYPE>
TVec4<TYPE> operator-(const TYPE val, const TVec4<TYPE> &v); // Subtract scalar and vector
template<class TYPE>
TVec4<TYPE> operator*(const TYPE val, const TVec4<TYPE> &v); // Multiply scalar and vector
template<class TYPE>
TVec4<TYPE> operator/(const TYPE val, const TVec4<TYPE> &v); // Divide scalar and vector
template<class TYPE>
TVec4<TYPE> &operator+=(TVec4<TYPE> &v, const TYPE val); // Add scalar to vector
template<class TYPE>
TVec4<TYPE> &operator-=(TVec4<TYPE> &v, const TYPE val); // Subtract scalar from vector
template<class TYPE>
TVec4<TYPE> &operator*=(TVec4<TYPE> &v, const TYPE val); // Multiply vector by scalar
template<class TYPE>

template<class TYPE>
TYPE operator*(const TVec4<TYPE> &a, const TVec4<TYPE> &b); // Multiply vectors(dot product)
template<class TYPE>
TVec4<TYPE> operator/(const TVec4<TYPE> &a, const TVec4<TYPE> &b); // Divide vectors
