Function Documentation

MaxComponent()

int MaxComponent ( const IPoint2 &  p )

inline

Remarks

Returns the component with the maximum abs value. 0=x, 1=y.

{
    return p.MaxComponent();
}

MinComponent()

int MinComponent ( const IPoint2 &  p )

inline

Remarks

Returns the component with the minimum abs value. 0=x, 1=y.

{
    return p.MinComponent();
}

Length()

float Length ( const IPoint2 &  p )

inline

Remarks

Returns the length of the IPoint2

{
    return p.Length();
}

LengthSquared()

constexpr int LengthSquared ( const IPoint2 &  p )

constexpr

Remarks

Returns the length squared of the IPoint2

{
    return p.LengthSquared();
}

DotProd()

constexpr int DotProd ( const IPoint2 &  a, const IPoint2 &  b  )

constexpr

Remarks

Returns dot product of two IPoint2

{
    return a % b;
}

operator*() [1/2]

constexpr IPoint2 operator* ( const IPoint2 &  a, int  f  )

constexpr

Remarks

Returns an IPoint2 multiplied by a scalar.

{
    return IPoint2(a.x * f, a.y * f);
}

operator*() [2/2]

constexpr IPoint2 operator* ( int  f, const IPoint2 &  a  )

constexpr

{
    return a * f;
}

operator+() [1/2]

constexpr IPoint2 operator+ ( const IPoint2 &  a, int  f  )

constexpr

Remarks

Returns an IPoint2 offset by (f,f).

{
    return IPoint2(a.x + f, a.y + f);
}

operator+() [2/2]

constexpr IPoint2 operator+ ( int  f, const IPoint2 &  a  )

constexpr

{
    return a + f;
}

operator-()

constexpr IPoint2 operator- ( const IPoint2 &  a, int  f  )

constexpr

Remarks

Returns an IPoint2 offset by (-f,-f).

{
    return a + -f;
}

operator/()

constexpr IPoint2 operator/ ( const IPoint2 &  a, int  f  )

constexpr

Remarks

Returns an IPoint2 whose x and y members are divided by a scalar.

{
    return IPoint2(a.x / f, a.y / f);
}
