Utilizing CT-scanned data from a real pig carcass, the tool provides a new edge in pork product development, allowing sellers and buyers a better way to communicate the product that they bring to the market, together. Using a <a href=\"http:\/\/www.dentsable.com\/haptic-phantom-omni.htm\">Phantom Omni<\/a>, the user is able to create, modify, and delete planar cuts to virtually create the type of pork product the seller is interested in. The phantom Omni provides volume-based haptic feedback allowing the user to &#8216;touch&#8217; the product in-creation.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"PorkCad 2\" width=\"500\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/oIshdCLaoL4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n<\/div>\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Publication and resources<\/h4>\n\n\n\n<ul>\n<li><strong>PorkCAD: Case study of the design of a pork product prototyper<\/strong><br>Lasse Farnung Laursen, Jakob Andreas B\u00e6rentzen, Takeo Igarashi, Michael Kai Petersen, Line Katrine Haarder Clemmensen, Bjarne Kj\u00e6r Ersb\u00f8ll, Lars Bager Christensen, in IASDR \u201913: 5th International Congress of International Association of Societies of Design Research, pp. 1134-1<br><a href=\"https:\/\/www.lasselaursen.com\/wp-content\/uploads\/2023\/05\/iasdr13-porkcad.pdf\">Local PDF<\/a> | <a href=\"http:\/\/design-cu.jp\/iasdr2013\/papers\/1134-1b.pdf\">Published PDF<\/a><\/li>\n\n\n\n<li><strong>Registration-based interpolation real-time volume visualization<\/strong><br>Lasse Farnung Laursen, Hildur \u00d3lafsd\u00f3ttir, Jakob Andreas B\u00e6rentzen, Michael Sass Hansen, Bjarne Kj\u00e6r Ersb\u00f8ll, in SCCG \u201912: Proceedings of the 28th Spring Conference on Computer Graphics, pp. 15-21<br><a href=\"https:\/\/dl.acm.org\/doi\/10.1145\/2448531.2448533?cid=81554950756\">Published PDF<\/a><\/li>\n\n\n\n<li><strong>Anisotropic 3D texture synthesis with application to volume rendering<\/strong><br>Lasse Farnung Laursen, Bjarne Kj\u00e6r Ersb\u00f8ll, Jakob Andreas B\u00e6rentzen, in WSCG \u201911: Winter School of Computer Graphics 2011, pp. 49-57<br><a href=\"https:\/\/www.lasselaursen.com\/wp-content\/uploads\/2023\/05\/wscg11-Aniso.pdf\">Local PDF<\/a> | <a href=\"http:\/\/findit.dtu.dk\/en\/catalog\/2282374649\">Published PDF<\/a><\/li>\n\n\n\n<li><strong>Improving texture optimization with application to visualizing meat products<\/strong><br>Line Clemmensen, Lasse Farnung Laursen, in Scandinavian Workshop on Imaging Food Quality 2011, pp. 81-86<br><a href=\"https:\/\/www.lasselaursen.com\/wp-content\/uploads\/2023\/05\/tr11-texopt.pdf\">Local PDF<\/a> | <a href=\"http:\/\/findit.dtu.dk\/en\/catalog\/184178346\">Published PDF<\/a><\/li>\n\n\n\n<li>Realistic Virtual Cuts<br>Lasse Farnung Laursen, ph.d thesis, supervised by Jakob Andreas B\u00e6rentzen and Bjarne Kj\u00e6r Ersb\u00f8ll in 2012<br><a href=\"https:\/\/www.lasselaursen.com\/wp-content\/uploads\/2023\/05\/phdthesis.pdf\" data-type=\"attachment\" data-id=\"133\">Local PDF<\/a><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Quick Facts<\/h4>\n\n\n\n<ul>\n<li>3 Year Ph.D. Project<\/li>\n\n\n\n<li>Real-time Volumetric Renderer running GeForce 280M SLi coded in C++<\/li>\n\n\n\n<li>Real-time hardware supported volume-data slicing<\/li>\n\n\n\n<li>Phantom Omni integration<\/li>\n\n\n\n<li>First of its kind, PorkCAD, computer aided pork product design<\/li>\n\n\n\n<li>Qualitative user-study with 8 participants, in collaboration with <a href=\"http:\/\/www.danishcrown.dk\">Danish Crown<\/a> and <a href=\"http:\/\/www.dti.dk\">Danish Technological Institute<\/a><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Post-mortem<\/h4>\n\n\n\n<p>Completed in 2012, PorkCAD was &#8211; at the time &#8211; the largest single continuous project of my career, spanning 3 years. I&#8217;d be lying if I said that the thesis turned out exactly how I had hoped which I imagine is the case for a significant number of Ph.d projects. At times struggled to retain an interest in the subject matter for the full 3 years. If it wasn&#8217;t for my follow-up post.doc project, which I adored, I&#8217;m not sure how I&#8217;d feel about my Ph.d thesis.<\/p>\n\n\n\n<p>I&#8217;m glad I finished it, but I still don&#8217;t know if I&#8217;d recommend undertaking one to other people.<\/p>\n\n\n\n<p>A final thought in terms of lessons learned, was the fact that both during the design and testing of PorkCAD its interface proved highly intuitive. I was how surprised at how quickly and easily senior personnel were able to use the system. Due to the <a href=\"http:\/\/www.dentsable.com\/haptic-phantom-omni.htm\">Phantom Omni<\/a>&#8216;s 6 degrees of freedom, PorkCAD could provide analogous movement of the controller and in-software point-of-interaction (pointer). It seems obvious in hindsight, but nothing comes close to scratching the intuitive nature of analogous behavior. If you have identical behavior occurring both on- and off-screen, then you&#8217;re on the right path.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Pork is big business in Denmark.
