The prefab panel allows you to quickly load
pre-saved Geomview files.  Each browser is
described below, followed by directions for
adding your own options to them.

bThe Environment Browser:
This browser allows you to load a Geomview
command file, which specifies windows, colormaps,
objects, camera positions,  . . . just about
everything about Geomview's state at a particular
time.  Loading one of these environments may or
may not remove other windows and objects.  This
is the best approach to a quick start-up, if you
want to load up a standard set-up.  To save a
command file, use Geomview's save option. (You
can get the save panel by typing the greater than
sign when you are in one of Geomview's windows.)

bThe Coormap Browser:  
This browser is used to apply a pre-saved
colormap to the current window (usually the last
one the mouse has been in).  In this application,
a colormap is a function that assigns color to
the vertices of an object according to the
"height" of those vertices in a particular
direction.   For more information about how to
make your own colormap, please see the help page
for the toolkit panel.  Right now saving a
colormap is tricky-- the best thing may be to
save a command file (see above) and then take out
the command beginning with "ND-color".  Note the
"no-color" option on this menu that removes a
colormap from the current window.

bThe Sampe Objects Browser:  
This browser contains a list of interesting
higher dimensional objects.  Loading one of these
objects via this browser causes all other
Geomview objects being displayed to be removed,
so if you would like to see several objects you
may like to use the standard Geomview load
option.  Saving objects should be done in the
usual way for Geomview.

bThe Modues Browser:
This browser contains a list of external modules
for Geomview that make use of its higher
dimensional functionality.  Many of these are
intended to help develop visualization skills,
and the authors would like to include other
modules as they are developed.

The contents of the browsers are determined by 
1) a default file in the Geomview default data
directory under the name NDview/scripts/.ndview
which references the objects which always appear
in these browsers, and 
2) a file named .ndview in the current directory 
(if any).  This file may contain lines of the 
form 
           label:type:filename
where label is the label to appear in the
browser, type is one of environment colormap
object module, and filename is the name of the
file to be loaded when the user clicks on the
line of the browser displaying that label.  Note
that the label and filename should not contain
any colons.  Geomview will complain if it is
unable to find a file when you try to load it.
An example line of the .ndview file is
flattorus:object:NDview/geom/thisobj.mesh
