If it helps, I've attached .osg files corresponding to the DT input points and the resulting (incorrect) output triangles. I'm encountering this on Windows with a VS8 build (both debug and release). -Paul
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Martz Sent: Thursday, December 14, 2006 3:32 PM To: 'osg users' Subject: [osg-users] DelaunayTriangulator issue, current CVS Geoff, Robert -- There appears to be a problem with the osgUtil DelaunayTriangulator in current CVS. At about line 774 in DelaunayTriangulator.cpp, three vertices corresponding to a "supertriangle" are added to the points list. What I'm seeing with the current code is that the last one of these vertices appears to be incorrectly included in the final triangulation (the result triangle mesh incorrectly extends outside my point domain in positive Y). If I change the order of these vertices so that the first vertex is last, then my triangulation incorrectly extends out in negative X. So, whichever vertex is last seems to mistakenly end up in the triangulation. This is with current CVS v1.12 of this file. If I back out to v1.11, the problem goes away. Any idea what might be going awry here? Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com <http://www.skew-matrix.com/> 303 859 9466
