So exactly how would someone release a rendering in

That depends on the license on the LDraw Parts Library
and the LDraw file for the model/scene.

The DAT file associated with the render is not subject to
the open source rules (since it is not a derivative work
but merely references the library as a tool)

Exactly.

so you can't force release of the DAT code.

But since the _rendering_ of the DAT file _is_ a derivative
work of the LDraw Parts Library, distributing the rendering
may change the game.

Assuming that the LDraw Parts Library is under a:

a) GPL or LGPL style license, the "viral effect" of the
    license means that those who get the rendering also
    should get (access to) the source for the DAT file and
    the relevant parts of the LDraw Parts Library.

b) BSD style license, there is no obligation to distribute
    any source files with the rendering.

(...) Perhaps the book authors could share some insight on this, because there are many books out there containing renderings. What legal hoops did they jump through in order to publish? Don (20 years ago, 10-Jun-04, to lugnet.cad.dev.org.ldraw)

(...) Actually I beliee that this is the exact case where the LGPL differes from the GPL. Since the Parts 'library' will only be referecned as a library, I think that (if the LGPL were used on it,) it's license wouldn't pollute the license of the (...)
