### 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 statesets which are currently

  declared as transparent, but should be opaque. Defaults to using the fixTranspancyMode MAKE\_OPAQUE\_TEXTURE\_STATESET\_OPAQUE.

- **--fix-transparency-mode** \<mode\_string\> - fix statesets which are currently

  declared as transparent but should be opaque. The mode\_string determines which 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

- **--use-world-frame** - Perform transformations in the world frame, rather

  than relative to the center of the bounding sphere.

- **--simplify** n - Run simplifier prior to output. Argument must be a

  normalized value for the resultant percentage reduction. Example: **--simplify** .5

-

  will produce a 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 is done in destination orientation

- **--smooth** - Smooth the surface by regenerating surface normals on

  all geometry nodes

- **--addMissingColors** - Add a white color value to all geometry nodes

  that don't have their own color values (**--addMissingColours** also accepted).

**--overallNormal**    - Replace normals with a single overall normal.

**--enable-object-cache** - Enable caching of objects, images, etc.

**--formats**          - List all supported formats and their supported options.

- **--format** \<format\> - Display information about the specified \<format\>,

  where \<format\> is the file extension, such as "flt".

**--plugins**          - List all supported plugin files.

- **--plugin** \<plugin\> - Display information about the specified \<plugin\>,

  where \<plugin\> is the plugin's full path and file name.
