Re: Alpha Shapes

• The original UIUC/NCSA 3D Alpha Shape Site has moved to Raindrop Geomagic
  It became www.alphashapes.org/alpha/index.html
  The old Alpha Shape Gallery is also there.

• Francois Belair's "brilliant" 2D Alpha Shapes Java Applet

• Pat Moran's 2D Alpha Shape Page (defunct)
• Fausto Bernardini's reconstruction page (sorry, also defunct)
