VR Juggler tools and binaries on GitHub

Now that the semester’s over, I’ve been able to catch up on a bit of a backlog and put up a few VR Juggler-related items on GitHub. For all these items, click the link to visit the GitHub repo, which will also show you a nicely-rendered README with more information.

  • Jconf Grapher – This is a Python script for parsing jconf files (including their inclusions) and outputting Doxygen code to draw a graph of devices, proxies, and proxy aliases. I’ve included a silly shell script wrapping this to directly output PDF files, and have also made a minimal GUI for exploring these graphs, using XDot and PyGTK. Cross-platform: runs anywhere Python, PyGTK, and Doxygen do. (Tested on Linux and Windows.) Free and open source (Boost Software License 1.0, a very permissive license), feel free to fork and improve!
  • Jconf Display Merger – As I’ve discovered that VR Juggler on Windows works better with fewer windows in favor of more viewports per window, I put together this Python script to automate the process of merging display windows in jconf files (appropriately re-adjusting origins and sizes, etc).  There’s a command-line version that works everywhere and merges all windows into a single one, and for more control, you can use the GUI that lets you select which windows to merge. GUI is built on PySide (the LGPL replacement for PyQt). Cross-platform (command-line requiring Python 2.4, GUI requiring Python 2.5, Qt 4.6+, and PySide), though I have only tested on Linux. Free and open source (Boost Software License 1.0, a very permissive license), feel free to fork and improve!
  • METaL JConf files – Our group at Iowa State University recently got a new virtual reality system, a three-wall CAVE called METaL. We’re using VR Juggler to build applications for it, and in the interest of both easily maintaining configuration files and providing an up-to-date example, I’m hosting the VR Juggler 3.0 jconf files for the system on GitHub. They’re still a bit of a work in progress, but definitely usable – if you have a similar system it might be easiest to fork them on GitHub for easy integration of improvements.
  • VR Juggler 3.0 Windows binaries – Building VR Juggler can be a bit tricky, and building software on Windows can be a bit of a hassle, so you can imagine that combining them isn’t necessarily something you want to be doing every day. The most recent “official” Windows binaries are for the ancient 2.2.1.  I’ve started building from SVN, on the 3.0 branch, and pushing the installed tree to GitHub, so I don’t have to build VR Juggler separately on every machine I use: I can just clone the repo, and pull when I update the build.  Right now I only have the 32-bit builds for VC9, but I anticipate eventually adding other variants. (They’ll be in different branches named accordingly.)

As always with any of my grad school-related work, if you use or build on anything I make available, I’d really appreciate hearing from you. Information on how our work is used is helpful when providing reports and seeking renewal of the funding that makes this possible.
