finaloverridevirtualinherited

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

mathematical motivation:

the equation of the plane is given by:
\( \vec n \cdot \vec x = \vec n \cdot \vec p,\)
where \( \vec n = (n_{x}, n_{y}, n_{z})\) denotes the normal vector of the plane, \( \vec p = (p_{x}, p_{y}, p_{z})\) one specific point on the plane and \( \vec x = (x,y,z) \) all possible points on the plane.
Given a line with:
\( \vec l(u) = \vec l_{1} + u \cdot \vec v \),
the solution for \( u \) can be written: \( u = \frac{\vec n (\vec p - \vec l_{1})}{\vec n \vec v}\)
If the denominator is 0 then the line lies:

either in the plane
perpenticular to the normal of the plane
