-Self-line crossing when cutting a bend
---------------------------------------
-
-The self-line-crossing may happen after a few bends have been skipped. E.g.
-ends of A<->B cross the line, but "swallow" a few more in between:
-
- ,______
- / \
- |___A | \ \
- \ | B\ | __
- \ | | | / \
- / | | |___,---,___/A |
- / | \_________________|
- \ |
- \ | \ \
- / / B\ | _ __
- ----/ / | | / \ / \
- / ,____/ | |___/ \___/A |
- / B| \_________________|
- |
-
-
-
-If a bend with 180+ deg sum of inflection angles is found, its line between
-inflection angles (AB in our examples) must be crossed with all the other bends
-to detect a possible line-crossing. This is O(N*M), where N is the total number
-of line segments, and M is the number of qualifying bends. It is expensive.
-
-Also, there is another way to remove self-crossing, without removing most of
-the bend. E.g. from:
-
- \ /
- B\ | __
- | | / \
- | |____/A |
- \__________|
-
-Instead of:
-
- \ /
- \/ A'
- B
-
-To:
-
- \ \_
- B\ `-,_.__
- | A' \
- | |
- \__________|
-
-But perhaps it doesn't look quite as natural. I will trust the original
-article to do the right thing here and remove the bend altogether.
-
-ALSO: the bends should be iterated from different directions:
-
-for i := 0; i < len(bends); i++ {
- for j := 0; j < i; j++ {
- ...
- }
- for j := len(bends); j > i; j-- {
- ...
- }
-}
-
-So if there are multiple bends between the baseline, they will be cut
-correctly.
-
-The Context of a Bend
----------------------
-
-Similar bends:
-
-> For example, if bend 1 has four unit areas and bend 2 has six unit areas, the
-> average size is five units, and the normalized areas of bends 1 and 2 are
-> 4/5=0.8 and 6/5=1.2, respectively.
-
-My comment: everything until this sentence is clear. However, "unit areas" is
-misleading: there is little reason to normalize areas, but leave the distances
-intact (if we'd like to normalize areas, it would make sense to square-root
-them).
-
-Removing that removes changes the meaning of the sentence that **euclidean
-distance** is normalized (the composite of the bend properties), rather than
-a single component.
