The advent of a number of tools,\nincluding new bindings for the Computational Geometry Algorithms Library\n(CGAL) and the ipython notebook make Python an ideal tool for experimentation\nwith fast and numerically robust algorithms.\n\nThe presentation will include demonstrations of a number of common two- and\nthree-dimensional computational geometry algorithms:\n\n * Triangulations (and Voronoi diagrams)\n * Mesh refinement\n * Intersection testing\n * Alpha shapes\n * Convex hulls\n * Constructive Solid Geometry\n * Minkowski Sums\n\n", "quality_notes": "", "copyright_text": "http://www.youtube.com/t/terms", "embed": "<object width=\"640\" height=\"390\"><param name=\"movie\" value=\"http://youtube.com/v/zWhMc3am7ao?version=3&amp;hl=en_US\"></param><param name=\"allowFullScreen\" value=\"true\"></param><param name=\"allowscriptaccess\" value=\"always\"></param><embed src=\"http://youtube.com/v/zWhMc3am7ao?version=3&amp;hl=en_US\" type=\"application/x-shockwave-flash\" width=\"640\" height=\"390\" allowscriptaccess=\"always\" allowfullscreen=\"true\"></embed></object>", "thumbnail_url": "http://i.ytimg.com/vi/zWhMc3am7ao/hqdefault.jpg", "duration": null, "video_ogv_length": null, "video_ogv_url": null, "video_ogv_download_only": false, "video_mp4_length": null, "video_mp4_url": null, "video_mp4_download_only": false, "video_webm_length": null, "video_webm_url": null, "video_webm_download_only": false, "video_flv_length": null, "video_flv_url": null, "video_flv_download_only": false, "source_url": "http://www.youtube.com/watch?v=zWhMc3am7ao", "whiteboard": "", "recorded": "2012-08-22", "added": "2013-01-15T14:29:49", "updated": "2014-04-08T20:28:27.033" }
