What is VR Slider:
VR Slider is a 3D stereoscopic slide viewer for the CAVE/ImmersaDesk
or the AGAVE passive
stereo display system. Users can control the slide show with the mouse/wand,
both in single-user mode or collabarative mode. It uses the CAVElib
for display and CAVERNsoft
for network synchronization. Furthermore it allows collaborators
to take control of the 3D pointer so that they can point at elements in
VR Slider reads .ppm (portable pixmap) images.
Note: If your images are larger than 512*512, the program will resample
it to fit 512*512. This limitation will be corrected in future versions.
How to compile:
VR Slider has been tested in both IRIX and LINUX 6.2 .
First, make sure
1. The path of CAVElib(CAVE_DIR=path line in Makefile)
2. The compiler (CPPCOMPILER=compiler line in Makefile)
3. The path of CAVERNsoft is correct.
CAVERN_DISTRIB in bash or bsh
Using setenv CAVERN_DISTRIB
path in csh
If everything is OK, type "make". Two exectuable files collabserver
and collabslider will be created.
Running in Single user mode:
If you want to use the VR Slider as a single user, simply type
vrslider ".ppm image pairs
you want to show"
make sure left eye image appear before right eye image in your command
e.g. vrslider left1.ppm right1.ppm
left2.ppm right2.ppm .....
Running in Collaborative mode:
If you want to work with your peers, you may want to share your information
and syncronize the sequence being displayed. To realize this function,
run server by typing
Every client who want to share the scene must have a copy of image
e.g. collabserver 40000
Then, each user run his/her own client by typing:
vrslider -c servername -p
port -n username ".ppm image pairs you want to show"
e.g. vrslider -c obiwan.kenobi.com
-p 40000 left1.ppm right1.ppm left2.ppm right2.ppm .....
