Detailed Description

Class for a conical surface in the ATLAS detector. It inherits from Surface.

The ConeSurface is special since no corresponding TrackParameters exist since they're numerical instable at the tip of the cone. Propagations to a cone surface will be returned in curvilinear coordinates.

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 cone, i.e. the symmetry axis of the cone is the z-axis, x- and y-axis are perpenticular to the the z-axis. In this frame the cone 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 points of intersection can be obtained as follows:

The cone is described by the implicit equation \(x^2 + y^2 = z^2 \tan \alpha\) where \(\alpha\) is opening half-angle of the cone the and the line by the parameter equation (with \(t\) the parameter and \(x_1\) and \(x_2\) are points on the line) \((x,y,z) = \vec x_1 + (\vec x_2 - \vec x_2) t \). The intersection is the given to the value of \(t\) where the \((x,y,z)\) coordinates of the line satisfy the implicit equation of the cone. Inserting the expression for the points on the line into the equation of the cone and rearranging to the form of a gives (letting \( \vec x_d = \frac{\vec x_2 - \vec x_1}{\abs{\vec x_2 - \vec x_1}} \)): \(t^2 (x_d^2 + y_d^2 - z_d^2 \tan^2 \alpha) + 2 t (x_1 x_d + y_1 y_d - z_1 z_d \tan^2 \alpha) + (x_1^2 + y_1^2 - z_1^2 \tan^2 \alpha) = 0 \) Solving the above for \(t\) and putting the values into the equation of the line gives the points of intersection. \(t\) is also the length of the path, since we normalized \(x_d\) to be unit length.
