This method is complete for d less than or equal to 3, where versions of this method run in time O(n alpha(n)) and O(n), n the number of simplices. An implementation of the algorithm is applied to alpha shapes, which is a novel geometric modeling tool."}],"intvolume":"        12","status":"public","page":"771 - 784","publication_status":"published","type":"journal_article","publisher":"Elsevier","date_published":"1995-11-01T00:00:00Z","volume":12,"doi":"10.1016/0167-8396(95)00016-Y","date_updated":"2022-06-24T09:49:32Z","citation":{"mla":"Delfinado, Cecil, and Herbert Edelsbrunner. “An Incremental Algorithm for Betti Numbers of Simplicial Complexes on the 3-Sphere.” <i>Computer Aided Geometric Design</i>, vol. 12, no. 7, Elsevier, 1995, pp. 771–84, doi:<a href=\"https://doi.org/10.1016/0167-8396(95)00016-Y\">10.1016/0167-8396(95)00016-Y</a>.","ista":"Delfinado C, Edelsbrunner H. 1995.
