This generalization leads to a family of straight-line graphs, \" \\alpha -shapes,\" which seem to capture the intuitive notions of \"fine shape\" and \"crude shape\" of point sets. It is shown that a-shapes are subgraphs of the closest point or furthest point Delaunay triangulation. Relying on this result an optimal O(n \\log n) algorithm that constructs \\alpha -shapes is developed.","lang":"eng"}],"date_published":"1983-06-01T00:00:00Z","oa_version":"None","year":"1983","volume":29,"status":"public","day":"01","article_type":"original","date_updated":"2022-01-25T12:55:07Z","publication":"IEEE Transactions on Information Theory","publisher":"IEEE","scopus_import":"1","_id":"4128","publication_identifier":{"eissn":["1558-0814"],"issn":["0018-9162"]},"author":[{"first_name":"Herbert","last_name":"Edelsbrunner","full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9823-6833"},{"first_name":"David","full_name":"Kirkpatrick, David","last_name":"Kirkpatrick"},{"last_name":"Seidel","full_name":"Seidel, Raimund","first_name":"Raimund"}],"intvolume":"        29","extern":"1","acknowledgement":"The authors express their appreciation for numerous constructive suggestions, which led to improvements on\r\nvarious phases of the manuscript, to Dr. Marvin Simon of JPL and to Professor George L.
