To make the interpretation of the results easier, the author uses a self developed animation routine (animation), capable of demonstrating the motion of predefined
3d-wireframe models on the screen within a Matlab figure. The definition of the bodies used
in the current example is shown in Listing 3. The animation is applied later for the static equilibrium, the eigenmodes and the numerical integration (see Listing 4, 6, 7). The routine and its interface will not be explained in detail here.
