 \section{Definition of a Bend}
 \label{sec:definition-of-a-bend}
 
+The original article describes:
+
+\begin{displayquote}[\cite{wang1998line}][]
+    A bend can be defined as that part of a line which contains a number of
+    subsequent vertices, with the inflection angles on all vertices included in
+    the bend being either positive or negative and the inflection of the bend's
+    two end vertices being in opposite signs.
+\end{displayquote}
+
+While it gives a good intuitive understanding of what the bend is, some more
+technical details would be appreciated.
+
+Figure~\ref{fig:fig8-definition-of-a-bend} illustrates article's figure 8,
+but with bends colored as polygons: each color is a distinctive bend.

-End line segments of all lines should also be part of the bend. That way, all
-line segments belong to 1 or 2 bends. This characteristic is not obvious when
-reading the introductory sections, but becomes unavoidable (there could be no
-other way) when reading the following sections in detail.
+Once the intuitive definition is established, here are some non-obvious
+characteristics that are necessary when writing code to detect the bends:
 
-First and last segments of each bend (except for the two end-line segments) is
-also the first vertex of the next bend. This is apparent when looking at the
-illustration of the detected bends.
+\begin{itemize}
+
+    \item End segments of each line should also belong to bends. That way, all
+        segments belong to 1 or 2 bends.
+
+    \item First and last segments of each bend (except for the two end-line
+        segments) is also the first vertex of the next bend.
+\end{itemize}
+
+Properties above may be apparent when looking at illustrations at this article
+or reading here, but they are nowhere as such when looking at the original
+article.
 
 \section{Gentle Inflection at End of a Bend}
 
+The gist of the section is in the original article:
+
+\begin{displayquote}[\cite{wang1998line}][]
+    But if the inflection that marks the end of a bend is quite small, people
+    would not recognize this as the bend point of a bend

+The illustration for this section was clear, but insufficient: it does not
+specify how many vertices should be included when calculating the end-of-bend
+inflection. We chose the iterative approach --- as long as the angle is "right"
 and the distance is decreasing, the algorithm should keep re-assigning vertices
 to different bends; practically not having an upper bound on the number of
 iterations.
 
-Additional example, not found in the original paper, is illustrated in
