I've done a little more work on the edger, and in the process I've discovered
it's a *dandy* integrity checker. Edges that don't match up to just two shapes
tend to leave one edge dangling; this helped me find an unnecessary triangle in
the cat. I also discovered another place where the triangles were done
incorrectly about the ears, and a messed-up vertex on the forepaws.
The only place the edger seems to fail in finding what should be an edge is
when part of that edge is accounted for. It doesn't understand yet that two
shapes might share part of an edge, not all of it. In this case I had a line
extending partway along the longer edge adjoining two quadrilaterals, and
needed a conditional line along the shorter edge that they shared. Ultimately I
had to fudge this; the edger thought both the long and short edges were single
edges because they didn't match up completely. I'll probably improve the
program soon to account for these cases.
Since I don't want to keep posting large .dat files to the news server, I'm
keeping the latest version of the cat part on my Lego site (fairly new and in
progress): http://www.lummoxjr.com/lego/legos.html
The newest .dat has the cat's inconsistencies and broken vertices fixed, as
well as all the conditional lines it needs.
