Navigation mode can be set via menus, or via specific keypresses; see below.
A mouse drag is done by pressing the left mouse button and moving the mouse.
A touch drag is done by pressing a finger down and dragging. Both are called drags.
Prints out all the options available in the current version.
Prints out the current FreeWRL version.
Forces FreeWRL to run in fullscreen mode if possible. Note that if your
have an alternate way to enable fullscreen rendering it may be best to
way instead. The fullscreen flag will not enable hardware acceleration
if it has
not already been enabled. (see also --big option)
Forces FreeWRL to run in 800x600 mode. See also --fullscreen option
Set the initial window geometry with the usual X window format string.
The browser will try to connect to the socket at host:port to
an EAI connection. This option is mostly for internal use by
the EAI libraries.
FreeWRL will behave as a server : it spawns a child browser, prints
its PID on STDOUT and exits. The child then reloads the url given on
the command line upon receipt of a SIGUSR1 signal.

Commmand Line Options - Stereovision
For each of shutter, anaglyph and sidebyside stereovision modes the
--eyedist, --screendist and --stereo numbers are used to place left and
right viewpoints in-scene.
The 2D screen cursor defaults to the right viewport alignment which
accomodates the dominant eye preference for most people.
Forces FreeWRL to start in shutterglas stereo mode via GLX_STEREO in
attributs of glXChooseVisual. This needs software and hardware like
XIG DX Platiuum Xserver on a Linux PC with 3DRelevator shutterglasses
IRIX on a SGI Indigo2 Impact with crystal eyes shutterglasses.
On some SGI machines, you need to switch to a stereo capable visual
as root with setmon/xsetmon and then restart the X Server.
If GL_STEREO is not available on your machine the view mode defaults to
flutter which alternates between left and right every few seconds in a
regular window, used for testing.
Renders stereovision using different colors for left and right eye. You
need color filters or special anaglyph eyewear to view stereoscopically.
L and R are each one of R,G,B,C,M,A
(red,green,blue,cyan,magenta,amber/yellow) and the most usual
combinations are --anaglyph RG or --anaglyph RB. The current version of
--anaglyph does not render textures.
Renders stereovision in 2 viewports in the same window. To view
stereoscopically, stretch the window to be twice your physical eyebase
or a few mm less. If you wear eyeglasses just put your glasses against
the screen and stretch the window till each lens is centered in a
viewport. Then aim your eyes to be parallel so each one is looking at a
different viewport. To help, hold a card or your hand halfway between
your face and the screen in such a way it blocks the opposite viewport
for each eye. If you have a mirror stereoscopy you can stretch the
window to match the eyebase of that.
Stereovision in-scene eyebase - disance between the eyes of the avatar, defaults to .06.
Stereovision screen eyebase - for sidebyside stereo: horizontal distance between viewports in screen fractions, default .6
