Trk::DiscSurface::DiscSurface	(	const Amg::Transform3D &	htrans,

Constructor for Discs from Transform3D and AnnulusBoundsPC This will use the converting factory in AnnulusBoundsPC to build an equivalent PC version.

The overall transform of this object will be htrans and an additional rotation to overlay the two bounds implementations exactly.

Parameters

htrans	Base transform. This should be the transform of the `PlaneSurface` on which `annbounds` is located
annbounds	Cartesian annulus bounds to convert
detElem	Additional explicit detector element

Note: During testing, no conversion of the underlying detector element was implemented. This polar coordinate surface will therefore link back to the cartesian detector element.

finaloverridevirtual

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
