_Overview_
Release 1.0
X11R4 based graphics tool for visualization of Tierra (1) data.
by Marc Cygnus & Daniel Pirone

-------------------------------------------------------------------------
Overview (ov) is a basic tool for the visualization of the spatial
distribution of Tierra "critters" births and deaths. New features
will be added as time allows.
ov communicates with a running tierra simulation via tcp/ip sockets.
This allows ov to talk to a simulation on the same machine, or on
a simulation running across the world ( isn't the net wonderful ? ).
The command syntax is :
ov machine.name port_num [high_water_mark [low_water_mark]]
where:
machine.name is the host machine's reachable address:
eg : tierra.slhs.ude.edu , or
tierra, or
128.175.41.33 ...
port_num is a positive integer ( usually 7001 or greater )
that is specified by the running tierra as its virtual port number
(VPORT).
high_water_mark is an optional parameter that sets an upper limit
on incoming packet buffering usually 50 is a good value for this
flow control setting. These are recommended for monitoring the
ip data flows.
low_water_mark is an optional parameter that sets an lower limit
on incomming packet buffering usually 40 is a good value for this
flow control setting. If a high_water_mark is set but not a low one,
the value of 2 ( very low! ) will be used.
Upon a successful connection, the size of the tierrain soup ( core )
will be printed, and soon an X window will need to be placed.
Along the left hand side a numeric scale of the the soup address will be
given. On the right, a slider for moving around in really large soups.
at the bottom, a ranked list of color - to - size mappings is presented.
The grey areas represent section of the soup that are not owned at that
moment.
In most X systems, the function keys F1 - F3 will select a magnification
range: F1 is the most "zoomed" in, F3 is farther out. Window resizing
is not fully supported, yet.
Adding the following lines to your ~/.Xdefaults will help the above.
Overview*memframe*translations: \
#override <Key>F1: SetRez(hi) \n\
<Key>F2: SetRez(med) \n\
<Key>F3: SetRez(lo) \n\
<Key>F4: SetRez(zoom) \n\
<Key>F5: SetRez(micro) \n\
<Btn1Down>: OrgQuery()\n
Overview*memscroll*translations: #override <Btn2Up>: RedrawMem()
Note: the micro and zoom modes are experimental, and metamorph at any point.
