Function Documentation

MaxComponent()

int MaxComponent ( const DPoint3 &  p )

inline

Remarks

Returns the component with the maximum abs value. 0=x, 1=y, 2=z.

{
    return p.MaxComponent();
}

MinComponent()

int MinComponent ( const DPoint3 &  p )

inline

Remarks

Returns the component with the minimum abs value. 0=x, 1=y, 2=z.

{
    return p.MinComponent();
}

Length()

double Length ( const DPoint3 &  p )

inline

Remarks

Returns the length of the DPoint3

{
    return p.Length();
}

LengthSquared()

constexpr double LengthSquared ( const DPoint3 &  p )

constexpr

Remarks

Returns the length squared of the DPoint3

{
    return p.LengthSquared();
}

DotProd()

constexpr double DotProd ( const DPoint3 &  a, const DPoint3 &  b  )

constexpr

Remarks

Returns dot product of two DPoint3

{
    return a % b;
}

CrossProd()

constexpr DPoint3 CrossProd ( const DPoint3 &  a, const DPoint3 &  b  )

constexpr

Remarks
