Definition at line 24 of file alvelocity3d.h.

Constructor & Destructor Documentation

AL::Math::Velocity3D::Velocity3D ( )

Create a Velocity3D initialize with 0.0f.

$\left[\begin{array}{c} xd \\ yd \\ zd \end{array}\right] = \left[\begin{array}{c} 0.0 \\ 0.0 \\ 0.0 \end{array}\right]$

AL::Math::Velocity3D::Velocity3D ( float pInit )

explicit

Create a Velocity3D initialize with the same float.

$\left[\begin{array}{c} xd \\ yd \\ zd \end{array}\right] = \left[\begin{array}{c} pInit \\ pInit \\ pInit \end{array}\right]$

Parameters

pInit the float value for each member

AL::Math::Velocity3D::Velocity3D	(	float	pXd,
		float	pYd,
		float	pZd
	)

Create a Velocity3D initialize with explicit value.

$\left[\begin{array}{c} xd \\ yd \\ zd \end{array}\right] = \left[\begin{array}{c} pXd \\ pYd \\ pZd \end{array}\right]$

Parameters

pXd	the float value for xd
pYd	the float value for yd
pZd	the float value for zd

AL::Math::Velocity3D::Velocity3D ( const std::vector< float > & pFloats )

Create a Velocity3D with an std::vector.

$\left[\begin{array}{c} xd \\ yd \\ zd \end{array}\right] = \left[\begin{array}{c} pFloats[0] \\ pFloats[1] \\ pFloats[2] \end{array}\right]$

Parameters

pFloats An std::vector<float> of size 3 for respectively: xd, yd, zd

Member Function Documentation

bool AL::Math::Velocity3D::isNear	(	const Velocity3D &	pVel2,
		const float &	pEpsilon = `0.0001f`
	)		const
