Hi, Does anyone know of some straight forward source code (if there''s such a thing!) showing how a force placed one 1 vertex of say a rectangular cube, alters it''s position & rotation? Cheers Sc0use

If I am not mistaken, what you are looking for are equations relating to torque.

i''m gonna do it again.

do a search for chris hecker or definition six. he''s got a great tutorial and source code along with it that explains force and torque very well.
