Figure 5.17 Transformation chain between the lowest and highest nodes
Figure 5.19 shows the algorithm designed and implemented in this research to
find the final transformation matrix of a child node inside the global coordinate
frame. Following this algorithm and recalling the example presented in Figure 5.16,
the global position of the steel section can be calculated as:
T
