as3geometry Update

I’ve been working on a GitHub geometry library recently.

I’ve created various of these over the years, AS1, AS2, AS3, and now AS3+as3signals. It is gratifying to finally have the means to define events in interfaces!

The work uses the alpha of ASUnit version 4 (Rob Penner’s ‘Free Runner’ implementation, though it is not purely Test-Driven Development because in some cases I am refactoring old hitherto-private code. However, the classes in the test repository might serve as a useful example of the upcoming ASUnit library.

The work aims for elegance of structure rather than speed, and I will be concentrating on the Euclidean 2D for the time-being, though may look at extending it into 3D or non-Euclidean plane structures if I ever have the time.

    Very nice! Is your goal to build something like Cabri Geometry or Geometer’s Sketchpad?
