Given a source and a target shape, our method blends them topologically and geometrically, producing continuous series of in-betweens as new shape creations. The blending operations are defined on a spatio-structural graph composed of medial curves and sheets. Such a shape abstraction is structure-oriented, part-aware, and facilitates topology manipulations. Fundamental topological operations including split and merge are realized by allowing one-to-many correspondences between the source and the target. Multiple blending paths are sampled and presented in an interactive, exploratory tool for creative 3D modeling. We show a variety of topology-varying 3D shapes generated via continuous structural blending between man-made shapes exhibiting complex topological differences, in real time.\n          <\/jats:p>","DOI":"10.1145\/2601097.2601102","type":"journal-article","created":{"date-parts":[[2014,7,22]],"date-time":"2014-07-22T15:08:20Z","timestamp":1406041700000},"page":"1-10","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":58,"title":["Topology-varying 3D shape creation via structural blending"],"prefix":"10.1145","volume":"33","author":[{"given":"Ibraheem","family":"Alhashim","sequence":"first","affiliation":[{"name":"Simon Fraser University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Honghua","family":"Li","sequence":"additional","affiliation":[{"name":"Simon Fraser University and National University of Defence Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Xu","sequence":"additional","affiliation":[{"name":"National University of Defence Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junjie","family":"Cao","sequence":"additional","affiliation":[{"name":"Dalian University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Ma","sequence":"additional","affiliation":[{"name":"Simon Fraser University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Simon Fraser University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2014,7,27]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.00575"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2461912.2462027"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/2945.928169"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/274363.274366"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2007.1002"},{"key":"e_1_2_2_6_1","volume-title":"Proc. of Geometric Modeling and Processing, 173--182","author":"Fu H."},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/383259.383282"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/133994.134004"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8659.2012.03042.x"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2185520.2185551"},{"key":"e_1_2_2_11_1","volume-title":"Proc. of Cyber Worlds, 0465--.","author":"Kanonchayos P."},{"key":"e_1_2_2_12_1","volume-title":"Proc. of Symp. on Geom.
