This is a very complex topic and not really one for these forums. I have explained it in as much detail as I intend to in the blog post. The source code is also very complex, and it's not mine to give away.
One thing I can comment on though, is that your 'normals' are not correct. They should be exactly in the center of the two main line segments, as I have drawn in green here:

Apart from that, it looks like you are doing a good job.

For each pair of two red lines, the normal should be exactly in the middle. Some of your blue lines are not in the middle.
