Re: T-Junctions re-visited

I do the unique tests first, optional (pending) T-Junction fixes are second and the final step takes care of generating normals (and thus extra vertices). This setup is the result of my rewrites this weekend, it gives me the most playing room for generating extra lookup tables etc in the early stages.

The way I do smoothing at the moment would require all kinds of extra tests (like the bc cb ones you mentioned) for it to work correctly on non BFC parts. So at the moment I'm assuming everything is BFC. When the results on BFC-ed parts are 'perfect' I'll take a look at those pesky nocertify ones to see what needs to be done extra.

I know on the part level if something is bfc (whole mesh is indeed ccw in such a case) or not, so in the end I could basically add two algorithms for handling smoothing, one for bfc (faster) and one for non bfc (probably much slower).

Even with this, non bfc parts don't actually look much worse at the moment, they only suffer from the dark/light spot here and there due to the mirroring you mentioned.
