3D - Viewer?

Joel Sheffield
I am having a problem with the 3D viewer plugin.  When I bring it up, it
seems to take a long while to load.  In the past, it has finally loaded
within a minute.  Once loaded, I can view many stacks in succession, but
the initialization is slow.  I believe that this is because it
automatically checks for updates.  On some computers, this process is
relatively quick, but on my laptop it is slow.

In any case, today, when I tried, the delay was so long that the entire
program crashed.  I went to the website neurofly.de, and received a timeout
error.  Is there something wrong with the site, and/or is there a way that
I can prevent the plugin from calling home (if that's what it is doing)?

Thank you all,
Joel

there is no checking for updates within the 3D Viewer plugin, so this
can not be the reason. It only checks locally on your machine which
version of Java3D is installed, and only if it detects a version which
is too old it will show you a message. So no silent connection to the
internet.

If you are using the 3D Viewer on ImageJ (and not Fiji), I'd recommend
to switch to the Fiji version. It is much newer, and it uses an updated
version of Java3D. It would at least be worth to try if the problem
remains when using it with Fiji.

Otherwise, starting ImageJ from the command line might give more hints
on where the program actually hangs.

Regarding the website: Yes, neurofly.de is down. The 3D Viewer
documentation has been moved to the Wiki:
https://imagej.net/3D_Viewer
https://imagej.net/3D_Viewer:_User_FAQs
https://imagej.net/3D_Viewer:_Developer_Documentation

Best wishes,
Bene
