usage: pp3d [-hm] Displays animations of three dimensional particle motion Flags: -h help -m monochrome ----------------------------------------------------------------------------- pp3d expects the following formatted input on standard input: ----------------------------------------------------------------------------- <np> ! Number of particles <size_1> ! Relative display size of particle 1 <size_2> ! Relative display size of particle 2 . . . <size_np> ! Relative display size of particle np <t_1> ! First display time <x_1_1> <y_1_1> <z_1_1> ! Coordinates of particle 1 at t_1 <x_1_2> <y_1_2> <z_1_2> ! Coordinates of particle 2 at t_1 . . . <x_1_np> <y_1_np> <z_1_np> ! Coordinates of particle np at t_1 <t_2> ! Second display time <x_2_1> <y_2_1> <z_2_1> ! Coordinates of particle 1 at t_2 <x_2_2> <y_2_2> <z_2_2> ! Coordinates of particle 2 at t_2 . . . <x_2_np> <y_2_np> <z_2_np> ! Coordinates of particle np at t_2 <t_3> ! Third display time . . . All values are expected to be real numbers except for <np> which is an integer. ----------------------------------------------------------------------------- pp3d keyboard assigments (commands are case-insensitive): ----------------------------------------------------------------------------- ESC: Exit program p: Pause/continue animation z: Zoom-in on solution domain x: Zoom-out on solution domain a: Enlarge marker size s: Reduce marker size q: Enlarge window size w: Reduce window size t: Start/stop tumbling y: Increase tumbling rate r: Decrease tumbling rate o: Toggle visibility of origin ----------------------------------------------------------------------------- Miscellaneous ----------------------------------------------------------------------------- The initial (default) viewing region is: -1 <= x <= 1 -1 <= y <= 1 -5 <= z <= 5 The base marker size is 5 pixels Markers can range from 3 to 20 pixels in size
