Class FrenetTrihedron

java.lang.Object
  edu.sdsc.mbt.viewers.GLViewerImpl.FrenetTrihedron

public class FrenetTrihedron

extends java.lang.Object

FrenetTrihedron encapsulates a LOCAL reference frame on a curve defined by the LOCAL tangent, normal and binormal vectors. Unlike a real Frenet trihedron though, this IS NOT a rectangular trihedron in general inspite the name of the class and the name of the three (unit) vectors that may suggest so. Meant to play the role of a Frenet trihedron but with the additional flexibility of NO IMPOSED orthogonality. Certainly, the Frenet equations DO NOT hold either, in general.
