Abstract
A three-dimensional anatomical model of the human body is extended with information on the orientation of muscle fibres. The orientation is interpolated using two sets with restrictions of different types. These sets consist of points, for which either the orientation or a normal of the orientation is known from detection by manual or automatic methods. The interpolation works iteratively and is based on averaging orientations in the 6-neighbourhood. The average of orientations is calculated by determination of their principal axis.
