NAME flow - strange attractors.
SYNOPSIS flow [-display host:display.screen] [-visual visual] [-window] [-root] [-count number] [-cycles number] [-periodic|-no-periodic] [-search|-no-search] [-rotate|-no-rotate] [-ride|-no-ride] [-box|-no-box] [-dbuf|-no-dbuf] [-ncolors number] [-delay number] [-fps]
DESCRIPTION Strange attractors formed of flows in a 3D differential equation phase space. Features the popular attractors described by Lorentz, Roessler, Birkhoff and Duffing, and can dis‐ cover entirely new attractors by itself.
OPTIONS -visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -window Draw on a newly-created window. This is the default. -root Draw on the root window. -count number Number of particles in the flow. Default: 3000 -size number Length of particle trails. Negative values indicate randomness. The computa‐ tional load of a given flow depends on (particle count) * (trail length). Default: -10 -cycles number Timeout before changing objects. 0 - 800000. Default: 10000. -periodic -no-periodic turn on/off periodic attractors. These are flows in 2 dependent variables, with a periodic dependence on a third independent variable (eg time). Flow will some‐ times choose to start all the particles in the same phase to illustrate the flow's cross-section. Default: on -search -no-search turn on/off search for new attractors. If this is enabled, a fraction of the com‐ puting cycles is directed to searching a 60-dimensional parameter space for new strange attractors. If periodic flows are enabled, these can be searched too. Watch carefully - you are quite likely to see mathematical objects that have never been seen before, and since the parameters are not recorded, you'll probably never see them again! Default: on -rotate -no-rotate turn on/off rotating around attractor. Default: on -ride -no-ride turn on/off ride in the flow. Default: on If both -rotate and -ride are enabled the viewpoint will occasionally fly between the two views. -box -no-box turn on/off bounding box. Default: on -dbuf -no-dbuf turn on/off double buffering. If Flow runs slowly in full screen, but fast in a smaller window (eg on old graphics cards with too little memory), try turning this option off. Default: on -ncolors number Number of Colors. Default: 200. -delay number Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.). -fps Display the current frame rate and CPU load.
ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
