Jason:
There are lots of 3D formats out there; some proprietary, some
semi-proprietary, and some completely open. Besides the 3D game
folks, there are the 3D art programs (e.g. 3D Studio Max) and
the 3D CAD/CAM folks (e.g. AutoCAD.) Each area has a plethora
of 3D formats.
I'm unconvinced that the current LDRAW format needs to be
replaced; however, there is nothing wrong with becoming familiar
with alternative 3D formats to grab ideas for LDRAW format
extensions.
I would recommend looking at VRML first; it is one of the cleaner
3D formats out there, with several books published on the topic.
It is frequently possible to borrow one of the VRML books via inter
library loan (ask your local librarian about ILL), rather than
having to outright purchase it. For a variety of reasons, VRML
never really connected in the marketplace, though.
My $.02,
