I implemented path sweeping with pen using this paper http://dev.gentoo.org/~dberkholz/tutorials/cairo/siggraph.pdf. Now, I am not so sure how to tessellate that path geometry. If you look at the paper (figure 5), this what I end up with. What I would like to get is just outline of that generated path sufficiently tessellated into triangles. Any pointers?
I attached screenshot of that figure 5 from the paper and markup what I would like to get.
BTW, all those calculations and geometry is in 2D only.
