inline float operator * (const Vec4& rhs) const

dot product

inline Vec4 operator * (const float& rhs) const

multiply by scalar

inline Vec4& operator *= (const float& rhs)

unary multiply by scalar

inline Vec4 operator / (const float& rhs) const

divide by scalar

inline Vec4& operator /= (const float& rhs)

unary divide by scalar

inline Vec4 operator + (const Vec4& rhs) const

binary vector add

inline Vec4& operator += (const Vec4& rhs)

unary vector add.

inline Vec4 operator - (const Vec4& rhs) const

binary vector subract

inline Vec4& operator -= (const Vec4& rhs)

unary vector subract

inline Vec4 operator - () const

negation operator. Returns the negative of the Vec4

inline float length( void ) const

Length of the vector = sqrt( vec . vec )

inline float length2( void ) const

Length squared of the vector = vec . vec

inline float normalize()

normalize the vector so that it has length unity returns the previous length of the vector

inline friend ostream& operator << (ostream& output, const Vec4& vec)

Vec4()

Vec4(float x, float y, float z, float w)

float _v[4]

bool operator == (const Vec4& v) const
