NAME

whitedune - graphical vrml97 editor and animation tool

SYNOPSIS


whitedune [ -4kids ] [ stereoviewoptions ] [ inputdeviceoptions [ axisoptions ] ] [ file.wrl ] [ file.xml ] ...

whitedune -illegal2vrml [ -prefix prefix ] protofile.wrl file.wrl ..

DESCRIPTION

whitedune is a graphical editor for the Virtual Reality Modeling Language (VRML97), ISO/IEC 14772-1:1997. Additionally it has support for the NurbsSurface Node described in VRML97 Amendment 1 Final Draft. It also can load vrml97 level X3D .xml files, if configured to use the NIST vrml97/x3d translators.

Dune has some basic support for stereographic view usually with shutterglases in OpenGL "quadbuffer" mode.

With the -4kids option whitedune is started with a simplified 3D modeller orientated menu intended for kids.

With the -illegal2vrml the whitedune program is reused as commandline program to repair VRML97 files with illegal extensions. See the illegal2vrml(1) manpage for more information.

STEREOVIEWOPTIONS

-nostereo
force non stereoview mode on Linux/UNIX (e.g. if you do not own shutterglases)
-stereo
force stereoview mode. Stereo is only supported for hardware/software combinations, that allow quadbuffer stereo ("stereo in a window"), NOT splitscreen stereo ("OpenGlVR"). Examples for hardware/software combinations with support for quadbuffer stereo are graphicscards with support for shutterglasses or "stereo cloneview" to connect beamers of a onewall.
-anaglyph glassestype
force expermential stereoview mode for use with colored anaglyph glasses. glassestype can be red_green, green_red, red_blue or blue_red.
-eyedist eyedistinmeter
Distance between the two eyes of the viewer. Default eyedistinmeter is 0.06, it can be negative to swap eyes (no need to reconfigure your hardware if eye swapping problems occure).
-screendist screendistinmeter
Distance between the eyes of the viewer and the mid of the monitor screen. Default screendistinmeter is 0.8.
-fieldofview fieldofviewindegree
Overwrite Field of View field in VRML viewpoints and set to fieldofviewindegree in degree. Good stereoviewing may want need to ignore the FieldOfView field of viewpoints. The fieldOfView of the human eye is about 18 degrees, the VRML default is 45 degrees.

INPUTDEVICEOPTIONS

The following options are only valid, if whitedune was compiled with matching inputdevice driver support (e.g. there is not support for a Linux joystick under IRIX).

-joystick joystickdevice

Only valid under Linux or M$Windows. Under Linux, joystickdevice is the device of Linux joystick (usually something like /dev/input/js0 or /dev/js0). Under M$Windows, the joystickdevice is a number. Depending from the M#Windows version, this number is either 0, 1 or a number from 0 to 15.

-SDLjoystick joystickdevice

Currently only valid under Linux, MacOSX, FreeBSD, NetBSD or OpenBSD. The joystickdevice is a number (e.g. 0, 1, 2, ...).

-spaceball spaceballdevice

spaceballdevice is the serial device connected to the spaceball (usually something like /dev/ttyd2 or /dev/ttyS0). Only valid if binary was compiled with libsball support.

-xinput xinputname

xinputname is the devicename supported by the Xinput Protocol (usually something like magellan or dialbox). Valid on most Unix/X11 implementations.

-xinputlist

This option print a list of Xinput devicenames that can be possibly used as xinputname for the -xinput option. Valid on most Unix/X11 implementations.

-aflock aflockdevice  [ aflockoptions  -tracker birdaddr -wand birdaddr

aflockdevice is the serial device connected to the Ascension Flock of Birds master transmitter (usually something like /dev/ttyd2 or /dev/ttyS0). Only valid if binary was configured/compiled with --with-aflock option. Dune assumes the following configuration: Multiple FOBs with single RS232 Interface to Host Computer (see "The flock of Birds, Installation and Operation Guide, Standalone and Multiple Transmitter/Multiple Sensors Configurations", Page 3 (chapter "Introduction"), Figure 2). birdaddr is the adress of the Bird Unit of the magnetic head tracker (-tracker) or "3D Mouse" (-wand) in the Fast Bird Bus (FBB adress) as configured with the dipswitches on the Bird Unit. This program need to have the Flock of Birds configured in the Normal Address Mode only (see Page 12, Figure 4 of the manual decribed above).

-headnavigation

Use current transformmode when using a headtracker. Default without this option is using only the translation mode. This default gives you a very natural reaction, when your head moves, the virtual world moves, but if your head only rotates, the virtual world stand still. With the headnavigation option, the virtual world reacts to head rotations, depending of the current transform mode. Be carefull when you use this feature while talking to a audience. Talking cause small and fast head rotations and will cause small and fast rotations of the virtual world. Your audience may get a impression like in a earthquake and is in danger to get motion sickness.

-sendalways

Tell whitedune that the device sends (almost) always values (do not switch to other VRML nodes to make sense of inputvalues). Automatically used for Ascension Flock of Birds device (-aflock).

-dontcarefocus

Inputdevice actions dont care about the window focus. This can be useful in situations, when you only work with one whitedune window, e.g. when using a onewall.

AXISOPTIONS

-x|-y|-z|-xrot|-yrot|-zrot=[-][integer_axisnumber][,[factor][,[accel][,[wheel][,ignore]]]]
-all|-allxyz|-allrot=[factor][,[accel][,[wheel][,ignore]]]
-none=integer_axisnumber
-axes=max_number_axes

AXISLEGEND

-

used to swap sign of value from axis

integer_axisnumber

Integer with the number of the axis, that should be used for the x y z xrot yrot zrot directions. This number may not be greater than the number of axes of the inputdevice.

The integer_axisnumber in the none option is used to disable this axis.

factor

Float with a multiplicator for the axes

The factors of the all, allrot and allxyz options are independend of the factors of the single axes.

accel

Float with a expotential accelerator for the axes

wheel

The string "wheel"
  wheel means this axis of the inputdevice will not deliver zero 
  if released

ignore

Float with the value (relative to the maximal value from the device) which will be ignored (insensitivity)

max_number_axes

Number of used axes, one of (2,3,4,5)
  This must be equal or less to the physical available 
  axes of a device. Main usage of this option is to disable 
  bad designed or mechanical defect axes e.g. when you wish, 
  this axis on a joystick would not exist

AFLOCKOPTIONS

This options are only valid for the Ascension flock of birds magnetic tracking system.

-baud baudrate

Baudrate of the serial line communicating with the transmitter. According to the flock of bird manual, the following baudrates are valid for serial line communication: 2400, 4800, 9600, 19200, 38400, 57600 and 115200. Default: 38400

-numbirds numberbirds

Number of "data delivering" birds attached to the transmitter (e.g. not counting the transmitter itself, if it is a Extended Range Controller (ERC)). Default: 2 (tracker and wand).

-master birdaddr

Adress of the master transmitter in the Fast Bird Bus (FBB adress) as configured with the dipswitches on the transmitter unit. Default: 1

-hemisphere FRONT_HEM|AFT_HEM|UPPER_HEM|LOWER_HEM|LEFT_HEM|RIGHT_HEM

Hemisphere used. Sit on the antenna block (with the legs near on the side of the text) to see, what is left or right 8-) Default: RIGHT_HEM

-sync 0|1

Synchronise (1) or not (0) data output to a CRT (Monitor) or your host computer. Synchronisation is used to elimiate magnetic effects of a Monitor using the CRT sync cable. Default: 0

-block 0|1

Set (1) or do not set (0) the FNDELAY flag to the filedescriptor of the serial port. Default: 0

-filter AC_NARROW | AC_WIDE | DC_FILTER

Enable different filters. Read the Flock of Birds manuals for more information. This option can be repeated to use multiple filters. Default: no filter set, using filter set by Flock autoconfiguration.

-suddenchangelock 0|1

Allow (0) or disallow (1) setting of messured position and orientation when a sudden large messurement occure. Default: 1

-calfile calibrationfile

Use a VR Juggler style file to calibrate position messurement.

-ignoresize delta

Ignore position jumps from flock bigger than delta. This is much like suddenchangelock, but pure software based. Default: 0

EXAMPLES

whitedune -nostereo
start whitedune this way, if you have a stereo capable visual, but no shutterglases or other shutterbased technology.
whitedune -xinput magellan -allxyz=10,100,,0.0000002 -xinput dialbox-1 -x=0 -y=2 -z=4 -xrot=1 -yrot=3 -zrot=5 -all=1000,,wheel

starts whitedune with a magellan xinputdevice with factor 10, acceleration 100 and a ignore value of 0.0000002 on the xyz axes and a dialbox device with
x axis = 0. axis
y axis = 2. axis
z axis = 4. axis
rotation around x axis = 1. axis
rotation around y axis = 3. axis
rotation around y axis = 5. axis
all axes use factor 1000 and all to not deliver zero if released
whitedune -joystick /dev/input/js0 -z=,3 -axes=3
starts whitedune with a linux joystick, set acceleration of the z axis to 3 and disables the 4. (5., 6., ...) axis.
whitedune -xinput magellan -all=100,,wheel -z=3 -xrot=2 -none=2
starts whitedune with a xinput/magellan device, swapping axis number 2 and axis number 3, with axis number 2 disabled.
whitedune -aflock /dev/ttyS1 -numbirds 2 -master 1 -wand 2 -tracker 3
starts whitedune with a Ascension Flock of Birds, master transmitter ( a Extended Range Controller (ERC)) at FBB adress 1 connected to the serial device /dev/ttyS1. Use 2 Birds, one attached to a "3D Mouse" device at FBB adress 2 and one attached to a head tracking device at FBB adress 3.

BUGS

Dune need valid vrml97 code to work, it can not load a invalid VRML97 file.
Currently the NIST.gov X3D translators fail to produce valid VRML97 code for some rare used nodes like VisibilitySensor or Collision. To avoid dataloss, the temporary .wrl files are kept in /tmp
whitedune is software in development, expect bugs. Unsuccessful crashes should be rare, successfully crashes allow to get back the data. (see "EXIT STATUS"). Currently not all VRML97 nodes are displayed (e.g. background, extrusion) or displayed correctly (e.g. text, viewpoint).
Please send bugmessages to http://sourceforge.net/tracker/?group_id=3356&atid=103356

DIAGNOSTICS

Exit status is 0 for successfull operation, 1 if inputfile can not be successfully read or other initialisation error, 2 in case of a X11 server crash. 11 in case of can not open display/X11 initialisation error.

EXIT STATUS

In case of a crash (e.g. X11 server crash or signal (coredump) in case of a internal error), whitedune tries to write it's contence to the file $HOME/.whitedune_crash_*_*.wrl
