Textures are not embedded in the VRML file by default. Only a reference to the texture file is written. This refer-
ence is a filename, not a URL. You may need to edit the VRML file by hand to find textures across a network, or
use the -tem option.
The -bf option is used to subdivide the model into spatially related submodels. Each of these submodels is placed
into its own file and included by the main file using WWW Inline nodes. The idea is to group objects of similar
size that are near each other into units that a browser can download on an as-needed basis. If the model is a room,
the main file would include the floor, ceiling, and walls. Subfiles might include a table or chairs. The table subfiles
might reference subfiles with books or a telephone. A browser would then be able to quickly download and
display the coarse features of the room (for example, the walls), while continuing to download the details (for
example, the table and books). For more information, see “Exporting VRML Files” on page 245.
-h Print help message.
-iw Do not use WWW Inline nodes. By default, the program writes out many sub-
files that are inlined by the main file. Inlining can improve the perceived perfor-
mance when downloading your model. Subfiles are downloaded only as
required by the browser.
-ldc n,n, ... Level of detail range cutoffs. The values must be increasing real numbers. Mul-
tiple distances are separated by commas and are ordered from the closest (fin-
est) LOD to the farthest (coarsest) LOD. Distances are in scaled model units, i.e.
the units of the input model times the scale factor provided with the -s option.
-ml n Minimum LOD to convert. n is a non-negative integer. Level 0 (the default) is
the coarsest LOD.
-nt Do not output textures.
-o filename Output filename. Files without a .vrl extension are given one. Default: to use the
same base name as the input file.
-s n Scaling factor for dimensions in file.
-t coord Target coordinate system (any permutation of XYZ with optional minus signs).
Default is X-ZY.
-tem Embed textures in outfile. Default: reference textures by filename only.
-u unit Length units of model in mm, cm, m, km, in, ft, or mi. Default is m.
-url name Prepends name to inline node URLs.
-v Show status messages. May appear multiple times for increased verbosity.
