The --geocentric flag in osgdem builds a round earth database in meters with the coordinate system origin being the center of the earth. When you place your models on the earth (position and orientation), you'll need to keep this in mind. If your models are in meters you should be good and no rescaling is needed.
Hopefully this addresses your question. -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Ethan Fahy Sent: Wednesday, October 12, 2011 9:53 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] Placing an object on a UTM file generatedwith osgdem I got everything working but have one more question: If the units of the object I am attaching to my terrain are in meters, and the original geotiffs that I started with before converting them using osgdem were also in meters, is any further scaling of the attached object necessary? I am worried that by converting the geotiffs to ive files using the --geocentric osgdem flag I may have changed the units of the terrain and may need some sort of ellipsoid model-based scaling equation for any objects that I attached to the terrain. Anybody have an answer to this? Much obliged. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=43359#43359 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
