[Qgis-user] concave hull/alpha shapes in QGIS

[maning sambale]

We have a nifty convex hull in ftools/vector plugin. I'm looking for
ways to create concave hulls.  I have a set of csv points as a source
to generate the polygon.  This is updated regularly by non-geo field
workers.  Any workaround to generate concave hull in QGIS?

Mappy new year to all!

PS. I've seen old discussions in the qgis-dev list.
