Member Function Documentation

dir()

const AngleDeg & rcsc::Ray2D::dir ( ) const

inline

get the angle of this ray line

Returns

const referenct to the member variable

inRightDir()

bool rcsc::Ray2D::inRightDir ( const Vector2D & point, const double & thr = 10.0 ) const

inline

check whether p is on the direction of this Ray

Parameters

point	considered point
thr	threshold angle buffer

Returns

true or false

intersection() [1/2]
