Thanks for the explanation.  For 3DLDF, I'm not that
concerned at the moment about the intersections of arbitrary
`paths'.  I only brought it up in the context of the
discussion resulting from Antonio Ramirez' original
question.  I would like to implement them, but the
intersections of geometrical figures that we've discussed
before have a higher priority.

I've looked through some books on NURBs, and decided that
I'd like to read Tiller and Piegl's _The NURBs Book_.  It
is, however, quite long.  The parser is already in a fairly
finished state, and I'm not yet entirely sure what I want to
work on next.  There are a couple of features that don't
require me to learn much new material, such as routines for
writing and reading fast-loading base files.  My lack of
mathematical knowledge is the bottleneck for some of the
other features I'd like to implement.

I wish the same to you and all the other subscribers.

Thanks, I look forward to hearing about it.
