Thanks for the kind words and the report. I'll try to figure out what is happening exactly!
Thanks for reporting the specific testcase! What "real number type" (i.e. type 'r') are you using? If you are using Doubles or Floats you may want to try Rational numbers...
Just as a heads-up; I've been working on an implementation of an O(n log n) time algorithm to compute the convex hull in R^3 (see hgeometry-devel). That then will also...
Thanks for reporting this! I'll try to have a look at this this weekend.
Seems this issue is related to having multiple colinear points. I've managed to reduce it to a point set with only 5 points. Let's see if I can fix it...
Ok, I finally had some time to think a bit more about this again. The core of the issue is that the input point set has colinear triples, for example...
I'm all for adding more functions for working with boxes and rectangles. For splitting a rectangle I guess we could implement something with type : Rectangle p r -> Matrix...
That sounds like a useful suggestion. There should be a fairly simple O(n log n) time sweepline algorithm to do something like that: Assume for ease of exposition that the...
ipe supports writing ipelets in lua and in c++. See e.g. [the ipe manual](https://web.archive.org/web/20200618074529/http://ipe.otfried.org/manual/ipelets.html) (for whatever reason the official manual webpages are down, so I linked to some version on...
