bool Trk::StraightLineSurface::globalToLocal ( const Amg::Vector3D glob,

Specified for StraightLineSurface: GlobalToLocal method without dynamic memory allocation This method is the true global->local transformation.


makes use of globalToLocal and indicates the sign of the locR by the given momentum

The calculation of the sign of the radius (or \( d_0 \)) can be done as follows:
May \( \vec d = \vec m - \vec c \) denote the difference between the center of the line and the global position of the measurement/predicted state, then \( \vec d \) lies within the so called measurement plane. The measurement plane is determined by the two orthogonal vectors \( \vec{measY}= \vec{locZ} \) and \( \vec{measX} = \vec{measY} \times \frac{\vec{p}}{|\vec{p}|} \).

The sign of the radius ( \( d_{0} \) ) is then defined by the projection of \( \vec{d} \) onto \( \vec{measX} \):
\( sign = -sign(\vec{d} \cdot \vec{measX}) \)

Implements Trk::Surface.

bool  forceDir,
Trk::BoundaryCheck  bchk 
) const
finaloverridevirtual

fast straight line intersection schema - standard: provides closest intersection and (signed) path length forceDir is to provide the closest forward solution

b>mathematical motivation: Given two lines in parameteric form:

  • \( \vec l_{a}(\lambda) = \vec m_a + \lambda \cdot \vec e_{a} \)
  • \( \vec l_{b}(\mu) = \vec m_b + \mu \cdot \vec e_{b} \)
    the vector between any two points on the two lines is given by:
  • \( \vec s(\lambda, \mu) = \vec l_{b} - l_{a} = \vec m_{ab} + \mu \cdot \vec e_{b} - \lambda \cdot \vec e_{a} \),
    when \( \vec m_{ab} = \vec m_{b} - \vec m_{a} \).
    \( \vec s(\lambda_0, \mu_0) \) denotes the vector between the two closest points
    \( \vec l_{a,0} = l_{a}(\lambda_0) \) and \( \vec l_{b,0} = l_{b}(\mu_0) \)
    and is perpenticular to both, \( \vec e_{a} \) and \( \vec e_{b} \).

This results in a system of two linear equations:

  • (i) \( 0 = \vec s(\lambda_0, \mu_0) \cdot \vec e_a = \vec m_ab \cdot \vec e_a + \mu_0 \vec e_a \cdot \vec e_b - \lambda_0 \)
  • (ii) \( 0 = \vec s(\lambda_0, \mu_0) \cdot \vec e_b = \vec m_ab \cdot \vec e_b + \mu_0 - \lambda_0 \vec e_b \cdot \vec e_a \)

Solving (i), (ii) for \( \lambda_0 \) and \( \mu_0 \) yields:

  • \( \lambda_0 = \frac{(\vec m_ab \cdot \vec e_a)-(\vec m_ab \cdot \vec e_b)(\vec e_a \cdot \vec e_b)}{1-(\vec e_a \cdot \vec e_b)^2} \)
  • \( \mu_0 = - \frac{(\vec m_ab \cdot \vec e_b)-(\vec m_ab \cdot \vec e_a)(\vec e_a \cdot \vec e_b)}{1-(\vec e_a \cdot \vec e_b)^2} \)
