NAME

flow − display of complex scientific data base

SYNOPSIS

/usr/people/demos/flow
/usr/people/mexdemos/flow  (GL2only)

DESCRIPTION

Flow displays about 20,000 data points and a few vectors.  The data is a three-dimensional display of the values of the Navier-Stokes equations for turbulent fluid flow in a channel.  The calculation was done at NASA-Ames on, of all things, the Illiac-IV. 

Simple mouse motions control the display.  Press LEFTMOUSE, move the cursor, and release the button to redraw the image with new altitude and azimuth.  Use MIDDLEMOUSE to control distance and twist.  RIGHTMOUSE starts a sequence of many short twists.  Any keyboard key switches the display from single-buffer mode (the initial state) to double-buffer mode or back.  Use ESC to exit from the program. 

DISPLAY OPTIONS (GL2 only)

Upon entry into the program, flow is set for NTSC or high resolution output, depending on the currently selected monitor.  The display monitor can be altered during program execution by pressing the proper control character.  Key Display Monitor CTRL-a60 HZ monitor
CTRL-b30 HZ monitor
CTRL-cNTSC (RS-170A) display
CTRL-dPAL (European Video) display

WINDOW MANAGER (GL2 only)

The window manager version of flow runs only under the 60 Hz display options.
