The Geomview
command looks at the DISPLAY
or
REMOTEHOST
environment variables to try to determine if you are
logged in from another computer. If either of these indicates that you
are, Geomview
will attempt to run Geomview on that
computer. In order for this to work, your network must be configured
such that the Mathematica computer can successfully rsh
to the
Geomview computer without giving a password.
You can also explicitly set the DisplayHost
option to the
Geomview
command to a sequência de caracteres which is the desired hostname, for
exemplo:
In[1] := << OOGL.m In[2] := Plot3D[Sin[x + Sin[y]], {x,-2,2},{y,-2,2}] Out[2] := -Graphics3D- In[3] := Geomview[%3, DisplayHost->"riemann"]
This displays the graphics %3
on the remote host named
riemann
.
Geomview
recognizes the sequência de caracteres "local"
as a value for
$DisplayHost
; it forces the graphics to be displayed on the local
machine.
In addition to knowing the name da machine you want to run Geomview
on, Geomview
needs to know the type of that machine (the setting
da CPU variable that corresponds to the machine;
see Source Code Installation).
By default, Geomview
assumes that it is the same kind of
computer as the one you are running Mathematica on. The MachType
option lets you explicitly specify the type do DisplayHost
computer; it should be one das sequências de caracteres "sgi"
or
"next"
ou "x11"
.
You can use SetOptions
to change the default DisplayHost
and MachType
. For exemplo,
In[4] := SetOptions[Geomview, DisplayHost->"riemann", MachType->"sgi"]
arranges for Geomview
to run Geomview on an SGI workstation named
riemann
.
