https://svn.boost.org/trac10/ticket/13382 <p> When OR operation is performed between 2 non-overlapping polygons that contain collinear points with the same y coordinate, the resulting set is empty. However, if collinear points are removed, the resulting set contains the 2 polygons. </p> <p> If generic polygon_set_data objects are used, the OR operation works fine. The problem appears when polygon_90_set_data objects are used in order to increase efficiency of boolean operations. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/13382 Trac 1.4.3 k.daloukas@… Mon, 08 Jan 2018 15:15:11 GMT https://svn.boost.org/trac10/ticket/13382 https://svn.boost.org/trac10/ticket/13382 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">boost_collinear_points_error.cpp</span> </li> </ul> <p> Example replicating the bug </p> Ticket anonymous Thu, 05 Apr 2018 08:47:26 GMT https://svn.boost.org/trac10/ticket/13382#comment:1 https://svn.boost.org/trac10/ticket/13382#comment:1 <ul> <li><strong>severity</strong> <span class="trac-field-old">Problem</span> → <span class="trac-field-new">Showstopper</span> </li> </ul> Ticket John Maddock Thu, 10 May 2018 12:03:11 GMT https://svn.boost.org/trac10/ticket/13382#comment:2 https://svn.boost.org/trac10/ticket/13382#comment:2 <ul> <li><strong>owner</strong> set to <span class="trac-author">Barend Gehrels</span> </li> <li><strong>component</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">geometry</span> </li> </ul> Ticket awulkiew Thu, 10 May 2018 15:58:37 GMT https://svn.boost.org/trac10/ticket/13382#comment:3 https://svn.boost.org/trac10/ticket/13382#comment:3 <ul> <li><strong>owner</strong> changed from <span class="trac-author">Barend Gehrels</span> to <span class="trac-author">Lucanus Simonson</span> </li> <li><strong>component</strong> <span class="trac-field-old">geometry</span> → <span class="trac-field-new">polygon</span> </li> </ul> Ticket
