double geo::Decomposer< Vector, Point, ProjVector >::Angle ( Vector_t const & v ) const

inline

Returns the angle of the projection from main direction.

Parameters

v	vector to get the angle of

Returns: the angle of the projection from main direction, in radians

The projection on the plane is taken, and its angle from the main direction is returned. That angle is defined in the range $\left[ -\pi, \pi \right]$ , so that it is 0 for a projection matching the main direction and $\pi/2$ for one matching the secondary direction.

Parameters

distance	distance of the target point from the wire plane
proj	projection of the target point on the wire plane
