We don't provide a program to compress VRML files directly. obj2cg and cgview
in the examples distribution are fully working and supported programs, but are
intended primarily as examples of how to extend classes such as ObjectFile with
compression functions, and as a means for developers to evaluate the potential
utility of compressed geometry in their applications.
There is lots of metadata and semantic content in a VRML file that cannot be
encoded into a compressed object and stored in a CompressedGeometryFile, which
is intended only as a resource file for storing the compressed geometry itself.
You'd have to define a new file format for compressed VRML that either
incorporates a way to embed compressed geometry directly or which references
objects in an associated CompressedGeometryFile instance.
It may be fairly straight forward to extend the VRML loader to handle
compressed geometry, but I haven't had the opportunity to evaluate that.
