With X3D, WebGL, and X3DOM, it is possible to visualize and interact with 3D models in a web browser. Frequently, three-dimensional objects are stored using the X3D file format for the web. However, there is no explicit topological information, which makes it difficult to design fast algorithms for applications that require adjacency and incidence data. This paper presents a new open source toolkit TopTri (Topological model for Triangle meshes) for Web3D servers that builds the topological model for triangular meshes of manifold or nonmanifold models. Web3D client applications using this toolkit make queries to the web server to get adjacent and incidence information of vertices, edges, and faces. This paper shows the application of the topological information to get minimal local points and iso-lines in a 3D mesh in a web browser. As an application, we present also the interactive identification of stalactites in a cave chamber in a 3D web browser. Several tests show that even for large triangular meshes with millions of triangles, the adjacency and incidence information is returned in real time making the presented toolkit appropriate for interactive Web3D applications.<\/jats:p>","DOI":"10.1155\/2014\/920985","type":"journal-article","created":{"date-parts":[[2014,4,3]],"date-time":"2014-04-03T17:10:28Z","timestamp":1396545028000},"page":"1-10","source":"Crossref","is-referenced-by-count":4,"title":["A Topological Framework for Interactive Queries on 3D Models in the Web"],"prefix":"10.1155","volume":"2014","author":[{"given":"Mauro","family":"Figueiredo","sequence":"first","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o Marinha e Ambiental (CIMA), Portugal"},{"name":"Instituto Superior de Engenharia, Universidade do Algarve, 8005-139 Faro, Portugal"}]},{"given":"Jos\u00e9 I.","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o Marinha e Ambiental (CIMA), Portugal"},{"name":"Instituto Superior de Engenharia, Universidade do Algarve, 8005-139 Faro, Portugal"}]},{"given":"Ivo","family":"Silvestre","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o Marinha e Ambiental (CIMA), Portugal"}]},{"given":"Cristina","family":"Veiga-Pires","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o Marinha e Ambiental (CIMA), Portugal"},{"name":"Faculdade de Ci\u00eancias e Tecnologia, Universidade do Algarve, 8005-139 Faro, Portugal"}]}],"member":"98","reference":[{"key":"4","first-page":"157","volume-title":"Precise object interactions using solid modeling techniques","year":"1993"},{"issue":"1","key":"5","first-page":"72","volume":"5","year":"2010","journal-title":"IADIS International Journal on Computer Science and Information Systems"},{"key":"6","year":"1988"},{"key":"7","year":"1990"},{"key":"9","first-page":"3","volume-title":"The radial-edge structure: a topological representation for non-manifold geometric boundary representations","year":"1988"},{"issue":"1","key":"11","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1080\/10867651.2001.10487533","volume":"6","year":"2001","journal-title":"Journal of Graphics Tools"},{"issue":"4","key":"12","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/10867651.1998.10487494","volume":"3","year":"1998","journal-title":"Journal of Graphics Tools"},{"issue":"1","key":"14","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1016\/S0097-8493(97)00081-2","volume":"22","year":"1998","journal-title":"Computers and Graphics"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1145\/1787234.1787271"},{"key":"20","year":"2007"}],"container-title":["The Scientific World Journal"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/920985.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/920985.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/tswj\/2014\/920985.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T06:57:51Z","timestamp":1498114671000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/tswj\/2014\/920985\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":10,"alternative-id":["920985","920985"],"URL":"https:\/\/doi.org\/10.1155\/2014\/920985","relation":{},"ISSN":["2356-6140","1537-744X"],"issn-type":[{"value":"2356-6140","type":"print"},{"value":"1537-744X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
