The basic elements of a Moflow visualization representing the motion of a six-atom subset of the AAV-2 capsid protein monomer. (a) The motion of each alpha carbon atom is represented by a natural cubic spline. The set of 3D coordinates over time for each atom define the control points. Each pathline is colored on a gradient from blue (start of trajectory), through red, to yellow (end of trajectory. (b) Added to the initial visualization is a set of spheres representing the position of the alpha carbon atoms for one pose of the molecule at a user-selectable time. (c) The full Moflow visualization for these atoms includes a set of semi-transparent ribbons between every other pair of atom pathlines. These ribbon-surfaces aid in visually ordering the pathlines as well as provide a motion cue helping the user to recognize the direction of motion.
