no. VMD does not modify the real coordinates. it will try to guess the
best "camera position" after loading a new file, though.

if you click on

Display->Axes->Origin

you will have three small vectors indicating not only the
position of (0.0,0.0,0.0) but also the directions of the
three principal axes.
