Modeling tools for the hyperpatch, including local control-point interactions, lofting operations and sweeping operations, are described. These operations, together with modeling tools generated for free-form surface design, form a powerful tool hierarchy for the design of complex solids. Techniques are also described by which these hyperpatches may be integrated into conventional visible-surface algorithms. With the defined methods, and the hyperpatch model, the complexity of free-form solid object construction was found to be significantly simplified. <\/jats:p>","DOI":"10.1142\/s0218195991000293","type":"journal-article","created":{"date-parts":[[2004,11,26]],"date-time":"2004-11-26T20:43:01Z","timestamp":1101501781000},"page":"455-471","source":"Crossref","is-referenced-by-count":3,"title":["UTILIZING PARAMETRIC HYPERPATCH METHODS FOR MODELING AND DISPLAY OF FREE-FORM SOLIDS"],"prefix":"10.1142","volume":"01","author":[{"given":"KENNETH I.","family":"JOY","sequence":"first","affiliation":[{"name":"Computer Graphics Research Laboratory, Division of Computer Science, Department of Electrical Engineering and Computer Science, University of California, Davis, CA, 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,1,25]]},"container-title":["International Journal of Computational Geometry &amp; Applications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218195991000293","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T18:33:50Z","timestamp":1565116430000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218195991000293"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,12]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2012,1,25]]},"published-print":{"date-parts":[[1991,12]]}},"alternative-id":["10.1142\/S0218195991000293"],"URL":"https:\/\/doi.org\/10.1142\/s0218195991000293","relation":{},"ISSN":["0218-1959","1793-6357"],"issn-type":[{"value":"0218-1959","type":"print"},{"value":"1793-6357","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,12]]}}}
