fast straight line intersection schema - provides closest intersection and (signed) path length

mathematical motivation:

The calculation will be done in the 3-dim frame of the cylinder, i.e. the symmetry axis of the cylinder is the z-axis, x- and y-axis are perpenticular to the the z-axis. In this frame the cylinder is centered around the origin. Therefore the two points describing the line have to be first recalculated into the new frame. Suppose, this is done, the intersection is straight forward:
may \(p_{1}=(p_{1x}, p_{1y}, p_{1z}), p_{2}=(p_{2x}, p_{2y}, p_{2z}) \)@_fakenlthe two points describing the 3D-line, then the line in the \(x-y\)plane can be written as \(y=kx+d\), where \(k =\frac{p_{2y}-p_{1y}}{p_{2x}-p_{1x}}\)such as \(d=\frac{p_{2x}p_{1y}-p_{1x}p_{2y}}{p_{2x}-p_{1x}},\)
and intersects with the corresponding circle \(x^{2}+y^{2} = R^{2}. \)
The solutions can then be found by a simple quadratic equation and reinsertion into the line equation.
