EMviq<\/strong> (Extended Matrix Visual Inspector and Querier<\/em>) is a complete, interactive 4D visualization and runtime interrogation tool developed by B. Fanini (CNR ISPC) for Extended Matrices – see Extended Matrix (E. Demetrescu, CNR ISPC) official website<\/a>. The tool focuses on automatic extraction<\/em> from GraphML<\/a> files (EMs) targeting 3D visualization<\/em>, ease-of-use and performance<\/em> – in order to establish a fast and robust pipeline within a multi-disciplinary team.<\/p>\n\n\n

In order to inspect and query at runtime a single Extended Matrix (EM)<\/a> described by GraphML, the tool automagically performs a translation<\/em> of the EM into appropriate runtime data structures, suitable for 3D interactive queries. These are extracted or re-computed whenever the EM is being modified:<\/p>\n\n\n

  1. The Proxy-Graph<\/em><\/strong>: a graph for real-time queries and interrogation, handling 3D proxies objects well defined in 3D space. Generation of such graph may include procedural sub-graphs (e.g. “Seriation Node”)  by procedurally instancing the referenced 3D proxy element into multiple locations, depending on transformation rules<\/li>
  2. Source-Graphs<\/strong><\/em>: an internal runtime representation of EM sources relationships (paradata)<\/span><\/li>
  3. A Timeline<\/em><\/strong>: a finite number of time-periods, identified by beginning and end values<\/span> <\/li><\/ol>\n\n\n

    EMviq (2020)<\/h2>\n\n\n\n

    A new version of EMviq <\/strong>is being currently developed within SSHOC project<\/a>. The new tool is completely web-based<\/em> – developed on top of new ATON 3.0<\/a> framework, thus inheriting all the features offered by ATON (no installation, cross-device usage, etc.). Such tool also introduces new smart search, and it is being integrated with ownCloud<\/a> and nextCloud <\/a>to provide distributed workflow among remote professionals.<\/p>\n\n\n\n

    You can have a quick look of current working prototype here<\/a> on a sample project that loads, parses and processes a sample EM (GraphML) online. You can try live smart search functionalities selecting for instance “Last Period Rec” on the timeline and searching “USV100<\/em>” (single proxy), “anvil<\/em>” (highligh nodes related to the anvil), “wall<\/em>” – or from “Last Period” searching “ground<\/em>” or “west<\/em>“\/”east<\/em>“.<\/p>\n\n\n
