Information

Utility functions are provided here which are usually not called directly by a user, but are needed in the functions of this package

The following functions are supported:

  curveLength                          Compute the length of a curve with adaptive quadrature
  dummy                                return a dummy Bspline with zero entries
  getNumberControlPoints        Compute the number of control points for the given data points
  getNumberControlPoints2        Compute the number of control points for the given data points
                                                                                                  and transformation matrices
  quat2T                               Compute the transformation matrix of the given quaternions
  T2quat                               Compute the quaternions of the given transformation matrix

Release Notes:

• Sept. 13, 2002 by Gerhard Schillhuber:
  first version implemented
• Oct. 17, 2002 by Gerhard Schillhuber:
  new functions: getNumberControlPoints, getNumberControlPoints2 compute the number of control points for the given data points. It's needed to initialize the curve.
