Gilles,
In regard to the roadmap, there has been steady progress but not much is
visible yet from the GitHub or JIRA point of view, unfortunately. I'm currently
working on the final items from the initial roadmap email I sent out, namely
the ones related to the BSP tree and Region API cleanup (GEOMETRY-32,
GEOMETRY-33, GEOMETRY-34, and GEOMETRY-24). It made the most sense to handle
all of these issues with a general refactoring of the core classes, which is
what I'm doing on my working branch
(https://github.com/darkma773r/commons-geometry/tree/geometry-32-working). I
currently have all of the BSP tree code done (the biggest chunk of this) along
with the 1D and most of the 2D Euclidean classes. I have yet to do Euclidean 3D
and spherical 1D and 2D. Here is a comparison of the old API vs the new API for
calculating the area of the difference of two 2D regions defined by vertex
paths:
--- Old API ---
DoublePrecisionContext precision = ...;
Vector2D[] aVertices = { ... };
Vector2D[] bVertices = { ... };
PolygonsSet a = new PolygonsSet(precision, aVertices);
PolygonsSet b = new PolygonsSet(precision, bVertices);
PolygonsSet c = (PolygonsSet) new
RegionFactory<Vector2D>().difference(a.copySelf(), b.copySelf());
double area = c.getSize();
--- New API ---
DoublePrecisionContext precision = ...;
List<Vector2D> aVertices = ...;
List<Vector2D> bVertices = ...;
RegionBSPTree2D a = LineSegmentPath.fromVertices(aVertices, precision).toTree();
RegionBSPTree2D b = LineSegmentPath.fromVertices(bVertices, precision).toTree();
a.difference(b);
double area = a.getSize();
I'll keep you updated as I get closer to finishing. It is a large change so we
will undoubtedly need to discuss quite a few things. Also, if anyone has free
time and wants to help with the spherical classes on my working branch, that
would definitely help speed things along.
Regards,
Matt

Gotcha...was going to offer to send it up if there was an appetite.
