With our representation, an object is decomposed into components and each component is modeled as an\n            <jats:italic>SDF tree<\/jats:italic>\n            , a novel data structure that uses multiple signed distance functions (SDFs) to further decompose the volumetric component into regions. Multiple signed distance functions collectively can represent non-manifold surfaces and deliver a powerful vector representation for complex volumetric features. We use\n            <jats:italic>multiscale embedding<\/jats:italic>\n            to combine object components at different scales into one complex volumetric object. As a result, regions with dramatically different scales and complexities can co-exist in an object. To facilitate volumetric object authoring and editing, we have also developed a scripting language and a GUI prototype. With the help of a recursively defined spatial indexing structure, our vector representation supports fast random access, and arbitrary cross sections of complex volumetric objects can be visualized in real time.\n          <\/jats:p>","DOI":"10.1145\/2070781.2024201","type":"journal-article","created":{"date-parts":[[2011,11,30]],"date-time":"2011-11-30T13:58:46Z","timestamp":1322661526000},"page":"1-8","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Multiscale vector volumes"],"prefix":"10.1145","volume":"30","author":[{"given":"Lvdi","family":"Wang","sequence":"first","affiliation":[{"name":"Tsinghua University"}]},{"given":"Yizhou","family":"Yu","sequence":"additional","affiliation":[{"name":"University of Illinois at Urbana-Champaign"}]},{"given":"Kun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Zhejiang University"}]},{"given":"Baining","family":"Guo","sequence":"additional","affiliation":[{"name":"Tsinghua University"}]}],"member":"320","published-online":{"date-parts":[[2011,12,12]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/130069.130126"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/566654.566581"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8659.2008.01254.x"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/344779.344899"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1073204.1073306"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8659.2005.00855.x"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/1360612.1360650"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/1276377.1276380"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/74333.74359"},{"key":"e_1_2_2_11_1","unstructured":"Perry R.
