options:
-O option - ReaderWriter option
--compressed - Enable the usage of compressed textures,
defaults to OpenGL ARB compressed textures.
--compressed-arb - Enable the usage of OpenGL ARB compressed textures
--compressed-dxt1 - Enable the usage of S3TC DXT1 compressed textures
--compressed-dxt3 - Enable the usage of S3TC DXT3 compressed textures
--compressed-dxt5 - Enable the usage of S3TC DXT5 compressed textures
--fix-transparency - fix stateset which are curerntly declared as transprent,
but should be opaque. Defaults to using the
fixTranspancyMode MAKE_OPAQUE_TEXTURE_STATESET_OPAQUE.
--fix-transparency-mode <mode_string> - fix stateset which are curerntly declared as
transprent but should be opaque. The mode_string determines
algorithm is used to fix the transparency, options are:
MAKE_OPAQUE_TEXTURE_STATESET_OPAQUE,
MAKE_ALL_STATESET_OPAQUE.
-l libraryName - load plugin of name libraryName
i.e. -l osgdb_pfb
Useful for loading reader/writers which can load
other file formats in addition to its extension.
-e extensionName - load reader/wrter plugin for file extension
i.e. -e pfb
Useful short hand for specifying full library name as
done with -l above, as it automatically expands to the
full library name appropriate for each platform.
-o orientation - Convert geometry from input files to output files.
Format of orientation argument must be the following:
X1,Y1,Z1-X2,Y2,Z2
or
degrees-A0,A1,A2
where X1,Y1,Z1 represent the UP vector in the input
files and X2,Y2,Z2 represent the UP vector of the
output file, or degrees is the rotation angle in degrees
around axis (A0,A1,A2). For example, to convert a model
built in a Y-Up coordinate system to a model with a Z-up
coordinate system, the argument may look like
0,1,0-0,0,1
or
-90-1,0,0
-t translation - Convert spatial position of output files. Format of
translation argument must be the following :
X,Y,Z
where X, Y, and Z represent the coordinates of the
absolute position in world space
--simplify n - Run simplifier on prior to output. Argument must be a
normalized value for the resultant percentage reduction.
Example: --simplify .5 will produce an 50 reduced model.
-s scale - Scale size of model. Scale argument must be the
following :
SX,SY,SZ
where SX, SY, and SZ represent the scale factors
Caution: Scaling will be done in destination orientation
--smooth - Smooth the surface by regenerating surface normals on
all geometry
--addMissingColors - Adding a white color value to all geometry that don't have
their own color values (--addMissingColours also accepted).
--overallNormal - Replace normals with a single overall normal.
--formats - Lists all supported formats and their supported options.
--format <format> - Displays information about the spefied <format>, where <format>
is the file extension, such as "flt".
--plugins - Lists all supported plugin files.
--plugin >plugin> - Displays information about the spefied <plugin>, where <plugin>
is the plugin's full path and file name.

osgConv Command Reference
The OpenSceneGraph utility osgConv reads 3D databases, applies basic operations to them, then writes them out as a single 3D database.
