Sample Collaborating Session on Collage
I log on to the matisse machine at matisse.vis.colostate.edu. This is
where my executables collage and ="CO_server are located.
(This is very important! See
Installing Collage for more details.) I type in
and get a small welcome window
that leaves after a few seconds
as well as a main window (which
stays throughout the session).
main window, I will click on Collaborate/Begin Session since I
know that a good friend and trusted ally of mine,
Mary, is going
to share this particular collage session with me. When the
Begin Session window prompts me
for a Server Port Number, I just pick an arbitrary number between
2048 and 65535, namely
4567. I have to let Mary
know, either by talk, e-mail, or the telephone the port number
and the server I am using. Once she knows,
it is easy for her to begin her own collage
session. To join me in my adventures, though, she must open the
Join Session window, and enter in
the appropriate Host and Port Number, in this case that
If we have the Show Participants option (under
Collaborate in the main window) working, then
you should see:
I will work on a sample set, called
test1.hdf. To open
this, I'll click on the File button in the main window, and choose
the Open option. This opens the file browser, Figure 10.
This will not automatically bring up the image. I must first
go through the HDF Browser
to choose the style. Be warned: the Help option on this
window in this version of Collage is empty.
Once I have chosen a style, I click on Transport/
Send Selection to open the window. Finally, I can see
my testing window (Figure 12). But can Mary?
To let Mary in on all the fun I will be having with the nonsense image,
all I need to do is click on the File/Publish button in the
upper left hand corner. Her main window then will show some sort of
atomic explosion in the square to the left, and then the window will
open for her. Now that we both have the window, I think it is time
to tell her about it. I could of course, just write in the window with
the option, but
the backspace doesn't work. That alone convinces me there has
to be a better way. Instead, I will open a
Chat Box using
the Tools button on the main window. Once I have entered
in my message in the Input box at the bottom, Mary will have
a Chat Box appear on her terminal with my message and
identification in it. So either of us can initiate the chatting,
or close our own boxes, but if we have something to say, then everyone
else that is on the collaboration session will see what we have to say.
So know your collaborators, or be nice. Or both.
Once the window is made public, everything I do is seen by Mary,
if she happens to be paying attention. There are many different
manipulation tools available to use with the file. First, there
is the Make Spreadsheet option under File. This will,
as it claims to, make a spreadsheet (Figure 13) of my data set, test1.hdf.
There are many different ways to emphasize what points you think
are right or wrong or strange. I have a few of them in Figure 13,
namely the arrow and the circle and square. Once again there is
a text button that will enable you
to write on the page. If you make a mistake, then there is an
erase icon, for either a small
space or a large area. If the whole thing is a mistake, then
you can use the Clear Overlay option available under
Edit. This will leave the original image and delete any
marks you might have made.
The small space that has been highlighted in black indicated the
region you wish to see graphed as a histogram.
To highlight, use the button
on the left and hold the mouse button down while you drag diagonally
over the area.
