An undirected graph is generated based on a set of finite n-dimensional space curves. One or more traversal modulations are selected and a directed graph is created by traversing the edges of the undirected graph and determining a direction, either a forward direction or a reverse direction, for each...http://www.google.de/patents/US6459431?utm_source=gb-gplus-sharePatent US6459431 - Method and apparatus for orientating a set of finite n-dimensional space curves
