man tovrmlx3d (1): Convert 3D models to X3D, format VRML / X3D to have nice indentation.

SYNOPSIS

tovrmlx3d [file] [options...]

tovrmlx3d Convert 3D models to X3D, format VRML / X3D to have nice indentation. The output model will be written on standard output.

tovrmlx3d takes the following arguments:

file: The 3D model file to open.
-h / --help: Print the help message and exit.
-v / --version: Print the version number and exit.
--encoding classic|xml: Choose X3D encoding. Default is "classic".
--force-x3d: Force conversion from VRML to X3D. Note that if you choose XML encoding (by --encoding=xml), this is automatic. Note that this works sensibly only for VRML 2.0 (not for older Inventor/VRML 1.0, we cannot convert them to valid X3D for now).
