Hi All, I have made several bug fixes and other improvements to the 3.6 branch since the 3.6.0 stable release a couple of weeks ago and now feel that they are worthwhile rolling into a 3.6.1 stable release so that all users get to benefit from them.
The key changes I have made are: 1) Fix a bug where the OSG was creating VBO's within Display Lists (caused a crash on a particular driver.) 2) Fix a bug in osg::Geometry::set*Binding() where it wasn't assigning a BufferObject when it should have (this caused a performance regression and crash with VAO usage.) 3) Replaced all remaining IntersectVisitor (which has been deprecated for many years) usage with the modern IntersectionVisitor and made the deprecated messages clearer in include/osgUtil/IntersectVisitor. (In OSG master I've removed this old class completely.) 4) Changed places that invoked the old osgUtil::TriStripVisitor so that they use the osgUtil::MeshOptimizers instead as these work far better when using VBO/VAO's. (In OSG master I also completely removed TriStripVisitor.) I don't expect my changes to break the build, but it's still not safe enough for me to tag 3.6.1 straight without getting some community feedback, so here I am again asking members of the community to check out the OpenSceneGraph-3.6 branch from github and tests the build and runtime on your build tools. If you are using OSG master then there is chance that your build will break if you use the old IntersectVisitor and TriStripVisitor classes, but then that's good, you should have rewritten you code long ago so now you have a reason to make the required improvements :-) Please let me know of success and failures, or any bugs you've seen in 3.6.0 but haven't reported yet :-) Cheers, Robert. ChangeLog since 3.6.0 Fri, 20 Apr 2018 14:32:34 +0100 Author : Robert Osfield Replaced osgUtil::IntersectVisitor usage with osgUtil::InteresectionVisitor Fri, 20 Apr 2018 10:24:17 +0100 Author : Robert Osfield Removed TriStripVisitor for default set of Optimizer passes as it doesn't generate efficient scene graphs Fri, 20 Apr 2018 09:57:04 +0100 Author : Robert Osfield Added osgUtil::optimizeMesh(osg::Node* node) convinience method Fri, 20 Apr 2018 11:42:31 +0100 Author : Robert Osfield Removed usage of the osgUtil::TriStripVisitor is it generates osg::Geometry that perform very poorly when using VBO and VAO's vs GL DisplayLists. With DisplayLists being deprecated in GL and VBO and VAO becoming standard it's best to standardize on using the osgUtil::MeshOptimizers instead of TripStrupVisitor Thu, 19 Apr 2018 19:43:14 +0100 Author : Robert Osfield Fixed the set*Binding() methods so that they assign BufferObjects when required Thu, 19 Apr 2018 19:42:51 +0100 Author : Robert Osfield Fixed messages Thu, 19 Apr 2018 19:41:51 +0100 Author : Robert Osfield Fixed the GLBufferObject size computation so that it takes into account padding. Thu, 19 Apr 2018 19:36:19 +0100 Author : Robert Osfield Replaced the use of osgUtil::TriStripVisitor with ogUtil::MeshOptimizer usage to improve performance. Fixed set setColorArray assignement to pass in the color binding Wed, 18 Apr 2018 10:02:43 +0100 Author : Robert Osfield Fixed the handle of boundary equalization Wed, 18 Apr 2018 09:33:12 +0100 Author : Robert Osfield Added --equalize-boundaries -e command line option to call terrain->setEqualizeBoundaries(true) Mon, 16 Apr 2018 17:53:38 +0100 Author : Robert Osfield Updated version number in prep for future 3.6.1 release. Mon, 16 Apr 2018 15:08:24 +0100 Author : Robert Osfield Fixed inline Drawable::draw(..) method Mon, 16 Apr 2018 15:05:11 +0100 Author : Robert Osfield Fixed Geometry::drawImplmentation() handling of VBO's to prevent them from being used when display lists are used. Sun, 15 Apr 2018 08:25:57 +0100 Author : Robert Osfield Replaced osgViewer::GraphicsWindow dynamic_cast as it's not neccessary. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
