NAME
vreng - 3D Virtual Reality ENGine
SYNOPSIS
vreng [options]
DESCRIPTION
VREng (Virtual Reality Engine) is a distributed 3D application
allowing navigation in virtual worlds connected over the Internet
using IP Any Source Multicast (ASM) Technology.
The user will benefit more from this experience if connected on the MBone
(IP Multicast Backbone), but if not, he beneficiates of the full-duplex
Reflector Unicast/Multicast (see -R option below).
See http://vreng.enst.fr/.
OPTIONS
vreng accepts the following options:
- -a, --address group/port/ttl
-
To use an explicit IP Multicast Address. Usually irrelevent,
this option is deprecated and used only for testing.
- -b, --skin g|y|w
-
To use alternative background colors (skin) of the Graphical User Interface
(GUI), 'g' for grey, 'y' for yellow, 'w' for white, black color is the default.
- -c, --clean
-
To clean the personnal cache located in ~/.vreng/cache/.
- -d, --debug mask
-
To validate debugging with a cumulative bit mask position.
A mask is a bit positionned in a 32 bits word. Masks can be
cummulative to trace different features.
- -f, --frames rate
-
Limits the number of frames per second to 'rate'.
If rate is null or this option has no argument, then
there is no limitation and the application can
use all the power of the CPU and the accelerator card.
- -g, --no-gravity
-
Starts without gravity.
- -h, --help
-
To show summary of command line options.
- -i, --infogl
-
To show current OpenGL infos (GL/GLU versions and extensions).
- -l, --look old|new
-
To choose look and feel between old one and new one.
- -m, --multicast
-
To use directly the MBone IP Multicast infrastructure,
opposite to -r,--reflector option.
- -n, --number
-
Number of simultaneous threads to download textures images.
- -p, --pseudo nickname
-
To use a pseudo name rather than the login name (default).
- -q, --quality
-
To involve a better quality when rendering textures,
to activate if a graphic card accelerator is present.
- -r, --reflector
-
To use the reflector Unicast/Multicast if your host is not on the MBone.
This option is strongly recommended if the case where, either
your host cannot benefit of IP Multicast routing protocols as PIM-SM,
or if your Internet Provider doesn't supply this service.
This option is set by default.
- -s, --silent
-
To disable sound effects.
- -t, --theme n|t
-
To use whether flashy neon buttons (letter 'n')
either plain text buttons (letter 't') in the menu bar of the user interface.
- -u, --universe url_server
-
To use an alternative universe defined by an other httpd server than the default.
- -v, --version
-
To show the current vreng's version number.
- -w, --world url
-
To play with a world scene defined by this URL.
The usual scheme is "http", but it is possible to use the "file" scheme
for testing your own world.
- -2, --fullscreen
-
To display with a double size window (width x 2, height x 2),
covering almost the full screen, but rendering performances will be slower.
- -T, --timetolive days
-
Cache time to live in the cache (default 3 days).
- --display host
-
To use an other X11 display than the default.
- --help-x
-
To show summary of Ubit toolkit options.
