How to run the demos
or load new models
To run the Viz demos, press the Demos button (top row of
side bar GUI).
Then, just press on the desired demo. Usually the interface is set
to freeze until all the models are loaded, so be patient.
To load a model, press the Load button (top row of side
bar GUI).
Navigate through the directory structure, and select the files you
want to load by clicking on them in the listbox, or using wildcards (use
*.wrl) in the Load filter entry box and pressing
Add
to sel. When you're done selecting all the files you need to load,
press the Load selected files to finish.
The latest models are in: /projects/viz/src/Models/stereo_zbinden/solxxx Scroll all the way down in the Load files interface, and you'll see
the stereo_zbinden/ directory.
You're environment variables are probably not set correctly. Try the following:
> unsetenv VIZHOME > unsetenv PYTHONPATH > source /projects/viz/src/vizsource > /projects/viz/src/Gui/goViz
Viz
has crashed: the 3D rendering window has disappeared
The main rendering server has crashed, there's not much you can do at this
point. You lost the scene of 3D objects you have loaded, but not the data
associated with the GUI, such as the Markers, so save everything you can
and restart Viz by pressing the Quit button of what's left
(the GUI) and type goViz again at the UNIX prompt.
To report any crash, please email
me with the following information:
Any output message from the winterm you started Viz from (ie where you
type goViz). If it's too long, copy/paste the last page.
Any message appearing in the Console window
The sequence of things you did to make it crash (if not too long), so I
can replicate the crash
Any other Error message or behavior from the SGI that could tell me why
it crashed
Your name and social security as well as credit card number, so I can charge
you big time for support.
The
Viz 3D rendering window doesn't die when I exit Viz
This bug has been observed after having used the Animation sequence feature
(accessible by the button ).
It's not a big deal, since you wanted to quit anyway, but it will keep
the port busy and prevent you to restart Viz. You can make it go away by
typing:
> killall mainViz
Viz is not responding
You can still fly around the world, but can't perform any functions from
the GUI, such as measurements, or Markers: pressing the buttons doesn't
have any effect anymore. This means that somehow, the sidebar has lost
connection with the 3D rendering window.
Save everything you need/can save.
If you need to make more operations, press the Setting button
(top row side bar GUI) -> Reset -> Comm. Warning:
this should only be used if you can't lose what you loaded and desperately
need to perform more operations. This mode hasn't been fully tested, and
might crash.
Restart only the GUI: press Quit and select Quit GUI
(as opposed to Exit Viz). Restart the GUI by typing: /projects/viz/src/Gui/topGUI.py
This should work for you, but it doesn't, restart Viz: press Quit
and type goViz again.
I am
lost in the 3D world, and don't know where I am.
To reset the Viewpoints, click on Setting (top row in side
bar GUI) -> Reset -> View 0.
Or press the the ViewAll button
from the viewer decoration (toolbar on the side of the viewer). To turn
on the decoration, click on the right mouse button anywhere in the viewer
and select Decoration from the pulldown menu.
