We introduce three improvements enabling the synthesis of more general distributions of elements. First, we extend continuous pair correlation function (PCF) algorithms to multi\u2010class distributions using a dependency graph, thereby capturing interrelationships between distinct categories of objects. Second, we introduce a new normalised metric for disks, which makes the method applicable to both point and possibly overlapping disk distributions. The metric is specifically designed to distinguish perceptually salient features, such as disjoint, tangent, overlapping, or nested disks. Finally, we pay particular attention to convergence of the mean PCF as well as the validity of individual PCFs, by taking into consideration the variance of the input. Our results demonstrate that this framework can capture and reproduce real\u2010life distributions of elements representing a variety of complex semi\u2010structured patterns, from the interaction between trees and the understorey in a forest to droplets of water. More generally, it applies to any category of 2D object whose shape is better represented by bounding circles than points.<\/jats:p>","DOI":"10.1111\/cgf.13627","type":"journal-article","created":{"date-parts":[[2019,6,7]],"date-time":"2019-06-07T14:34:52Z","timestamp":1559918092000},"page":"157-168","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Accurate Synthesis of Multi\u2010Class Disk Distributions"],"prefix":"10.1111","volume":"38","author":[{"given":"Pierre","family":"Ecormier\u2010Nocca","sequence":"first","affiliation":[{"name":"LIX, \u00c9cole Polytechnique"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pooran","family":"Memari","sequence":"additional","affiliation":[{"name":"LIX, \u00c9cole Polytechnique"},{"name":"CNRS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Gain","sequence":"additional","affiliation":[{"name":"University of Cape Town"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie\u2010Paule","family":"Cani","sequence":"additional","affiliation":[{"name":"LIX, \u00c9cole Polytechnique"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,6,7]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1137\/0216006"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/1882261.1866188"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1145\/2508363.2508375"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2012.94"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8659.t01-1-00600"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1145\/3130800.3130819"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1145\/2766975"},{"key":"e_1_2_8_9_2","doi-asserted-by":"crossref","unstructured":"GuErinE.
