usage: xfpp3d [-h] [-c] Displays animations of three dimensional particle motion. Options: -h Displays this help message. -c Enables user-specified coloring (RGB) of particles. xfpp3d reads ASCII input from standard input in one of the following two formats: FORMAT 1: Default (all particles displayed in single, fixed color) ! Number of particles ! Relative display size of particle 1 ! Relative display size of particle 2 . . . ! Relative display size of particle np ! First display time ! Coordinates of particle 1 at t_1 ! Coordinates of particle 2 at t_1 . . . ! Coordinates of particle np at t_1 ! Second display time ! Coordinates of particle 1 at t_2 ! Coordinates of particle 2 at t_2 . . . ! Coordinates of particle np at t_2 ! Third display time . . . All values are expected to be real numbers except for which is an integer. FORMAT 2: User-specified coloring (enabled via -c option). Colors are specfied as RGB (red-green-blue) triples, where each color component is a real number between 0.0 and 1.0. ! Number of particles ! Relative size and color of part. 1 ! Relative size and color of part. 2 . . . ! Relative size and color of part. np ! First display time ! Coordinates of particle 1 at t_1 ! Coordinates of particle 2 at t_1 . . . ! Coordinates of particle np at t_1 ! Second display time ! Coordinates of particle 1 at t_2 ! Coordinates of particle 2 at t_2 . . . ! Coordinates of particle np at t_2 ! Third display time . . . All values are expected to be real numbers except for which is an integer.
