Hi Ulrich, Thank you very much for your answer and forgive me for taking too long to respond
I used two sets of data from the external application and saved the scene graph to corresponding osg files. Here are some statistics: The first osg file is 138 MB and the scene graph has 2864009 vertices, 7852 points, 9968 line loops and 348619 line strips. When loaded with osgviewer it has a memory footprint of 117 MB The second osg file is 126 MB and the scene graph has 800843 vertices, 3 points, 602 line loops and 186700 line strips. When loaded with osgviewer the memory usage is 257 MB No texturing is used in any of those graphs Best Regards Nikos ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=50726#50726 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
