The Mirror_toroid_pothole Component
Toroidal shape mirror (in XZ)

Description
This is an implementation of a toroidal mirror which may be curved in two dimensions. To avoid solving quartic equations, the intersection is computed as a combination of two intersections. First, the ray is intersected with a cylinder to catch (almost) the small radius curvature. Secondly, the ray is the intersected with an ellipsoid, with the curvatures matching that of the torus. The first incarnation (Mirror_toroid.comp) the mirror curves outwards (a bump), but this incarnation (Mirror_toroid_pothole) curves inwards (a pothole). Example: Mirror_toroid_pothole( radius=0.1, radius_o=1000, xwidth=5e-2, zdepth=2e-1,R0=1, coating="")
