In 2001, Justin Gullingsrud, and Paul Grayson, and John Stone added support for haptic feedback devices and further developing the interface between VMD and NAMD for performing interactive molecular dynamics simulations.
U 2001., Justin Gullingsrud, Paul Grayson, i John Stone su dodali podršku za povratno spregnute (engl. feedback) uređaje, i razvili su interfejs između VMD i NAMD za podršku interaktivnih molekularno dinamičkih simulacija.
