True. That buffer one might seem deceiving, indeed.<br>
<br>
The algorithms are mentioned on this page:<a
href="http://geometrylibrary.geodan.nl/ogc.html">
http://geometrylibrary.geodan.nl/ogc.html</a><br>
(where buffer is not mentioned at all). There is also written there:
<blockquote type="cite"><span class="Apple-style-span"
style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Grande'; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px;">Readers
might notice that many OGC algorithms, especially the more complex
ones, are not yet implemented and that is true. Much work has been done
on the generic structure of the library, algorithms still have to be
worked on. On the other hand many algorithms are implemented for
different coordinate systems (distance is implemented using four
strategies: Pythagoras, Andoyer, Vincenty and haversine, there is the
"spherical polygon area").</span></blockquote>
so it might be good to repeat that here. We don't want to give the
impression that all OGC algorithms are already there.<br>

<pre wrap="">Because of this the library is following OGC conventions loosely, not
strictly. All algorithms are implemented as standalone functions, instead of
methods on geometries. Nevertheless, OGC conventions, names and meanings are
followed as much as possible. Not all OGC algorithms are already
implemented. On the other hand the library offers other things such as
distance calculations over the globe.

What algorithms *are* implemented? I see that buffer exists, but only
for boxes. (!)
