Package mbdyn :: Package interface :: Module vectors

Module vectors

source code

VTK reference frames and vectors for the MBDyn post processing. Until now, the main class used is ReferenceFrame for representing the orientation matrix of the nodes and reference frames. The Vector class could also been used for representing velocities as a future development and it will certainly be a based to represent angular velocities as well.
