Re: [chimera-dev] Accessing rotation matrix of molecule models

Hi Mike, I forgot to mention that the difference between the OpenState localXform(xform) and globalXform(xform) routines. These routines change the current openState.xform by multiplying the xform argument on the right or left respectively. If c = atom.coord() and orig_xf is the current openState.xform then the displayed position is orig_xf * c. After calling openState.localXform(xform) the displayed position is orig_xf * xform * c, while after openState.globalXform(xform) the displayed position is xform * orig_xf * c. Tom
