Maybe you can look at Quaternions (I actually have infintessimal idea of how this works). Perhaps the physcists on the forum can elighten us..... http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation In mathematica it can be implimented using the package <<Algebra`Quaternions` Another good resourse might be David Parks website http://home.earthlink.net/~djmp/Mathematica.html Where he has some packages that might be useful to you Hope this helps or makes any sense Pratik Desai -- Pratik Desai Graduate Student UMBC Department of Mechanical Engineering Phone: 410 455 8134
