Utility
Simplifying complex rail turnout geometry for computing and converging connections
10 Oct 23
In various embodiments, techniques are provided for determining a connection between a rail turnout and another rail turnout or other rail element by a geometry connection process of rail network design software, by reducing the actual complex geometry of the rail turnout to a simplified arc, which at one end is tangent to the geometry of a connecting element at end of the rail turnout and at the other end is tangent to the geometry of a parent base element of the rail turnout.
