We present a new approach for raytracing of subdivision surfaces. The algorithm uses a projection of the ray onto the surface and works mainly intwo dimensions along this projection. While proceeding from patch to patch, we examine the bounding volume oftheir borders: the lower the distance between ray and subdivision surface, the more refinement steps are adaptivelyapplied to the surface but only along the projection of the ray. The adaptive refinement of a patch is controlled bycurvature, size, its membership to the silhouette, and its potential contribution to the light transport. The algorithmis simple and mainly consists of elementary geometric computations. Hence it is fast and easy to implementwithout the need for elaborate preprocessing. The algorithm is robust in the sense that it deals with all features ofsubdivision surfaces like creases and corners.<\/jats:italic> <\/jats:p><jats:p>Categories and Subject Descripters (according to ACM CCS): I.3.7 [Computer Graphics]: Raytracing<\/jats:p>","DOI":"10.1111\/1467-8659.t01-2-00703","type":"journal-article","created":{"date-parts":[[2003,11,4]],"date-time":"2003-11-04T18:30:59Z","timestamp":1067970659000},"page":"553-562","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Adaptive Ray Tracing of Subdivision Surfaces"],"prefix":"10.1111","volume":"22","author":[{"given":"Kerstin","family":"M\u00fcller","sequence":"first","affiliation":[]},{"given":"Torsten","family":"Techmann","sequence":"additional","affiliation":[]},{"given":"Dieter","family":"Fellner","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2003,11,4]]},"reference":[{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0010-4485(78)90110-0"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-61542-9_18"},{"key":"e_1_2_11_4_2","first-page":"337","article-title":"Ray Tracing Trimmed Rational Surface Patches","volume":"17","author":"Nishita T.","year":"1990","journal-title":"SIGGRAPH 90 proceedings"},{"key":"e_1_2_11_5_2","first-page":"171","article-title":"On Ray Tracing Parametric Surfaces","volume":"12","author":"Toth D.T.","year":"1985","journal-title":"SIGGRAPH 85 proceedings"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01911005"},{"key":"e_1_2_11_7_2","first-page":"69","volume-title":"9th Eurographics Workshop on Rendering proceedings","author":"Kobbelt L.","year":"1998"},{"key":"e_1_2_11_8_2","volume-title":"Master thesis, University of Utah","author":"Loop C.","year":"1987"},{"key":"e_1_2_11_9_2","unstructured":"J.E.Schweitzer.Analysis and Application of Subdivision Surfaces.PhD thesis University of Washington 1996."},{"key":"e_1_2_11_10_2","article-title":"Evaluation of Loop Subdivision Surfaces","author":"Stam J.","year":"1999","journal-title":"SIGGRAPH 99 Course Notes"},{"key":"e_1_2_11_11_2","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.00407"},{"key":"e_1_2_11_12_2","doi-asserted-by":"crossref","unstructured":"K.PulliandM.Segal.Fast Rendering of Subdivision Surfaces.Technical report University of Washington 1996.","DOI":"10.1007\/978-3-7091-7484-5_7"},{"key":"e_1_2_11_13_2","first-page":"274","volume-title":"Eurographics Rendering Workshop Proceedings","author":"Wald I.","year":"2001"},{"key":"e_1_2_11_14_2","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.00508"},{"key":"e_1_2_11_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-61062-2_2"}],"container-title":["Computer Graphics Forum"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2F1467-8659.t01-2-00703","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1467-8659.t01-2-00703","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,8]],"date-time":"2023-10-08T18:13:13Z","timestamp":1696788793000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1467-8659.t01-2-00703"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,9]]},"references-count":14,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2003,9]]}},"alternative-id":["10.1111\/1467-8659.t01-2-00703"],"URL":"https:\/\/doi.org\/10.1111\/1467-8659.t01-2-00703","archive":["Portico"],"relation":{},"ISSN":["0167-7055","1467-8659"],"issn-type":[{"value":"0167-7055","type":"print"},{"value":"1467-8659","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,9]]},"assertion":[{"value":"2003-11-04","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
