The surfaces of biomolecules are alive with activity, with surface shape and electrostatic interactions leading them to interact with each other. The recent VMD 1.9.1 release includes a new "QuickSurf" graphical representation for molecular surfaces that allows the dynamics of large biomolecules to be animated interactively for the first time. VMD 1.9.1 even enables surface representations for many-million atom complexes. QuickSurf uses fast algorithms, GPU computing techniques, and multi-core CPUs to achieve astonishing performance. The algorithms behind QuickSurf have been recently reported. VMD 1.9.1 adds many other new features including a new Force Field Toolkit (FFTK) plugin that assists researchers in development of CHARMM force field parameters, a new NetworkView plugin for mapping and displaying networks on 3-D molecular structures, an updated ViewChangeRender plugin for making sophisticated demonstrations and movies, and a new VMD remote control tool that allows VMD sessions to be controlled from wireless touch sensitive phones and tablet devices. For more on these and other new features of VMD see the VMD 1.9.1 release page.
