Deniz, Which method in EllipsoidModel were you using to do the transform from (lat,lon,alt) to (X,Y,Z)?
Can you provide a code snippet on how you're doing the transform? Also provide the actual osgdem command you're using to build your database... -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of deniz diktas Sent: Tuesday, December 28, 2010 1:10 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] [vpb] geographic to geocentric coordinatetransformation Hi Shayne, thank you for your reply. but the problem I am facing is related to the transformation. But I will keep your suggestion in mind when placing the camera, so thanks again :) The input to the application will be a flight-path given as a list of consecutive points in geographic coordinates which have to be transformed to geocentric coordinates (I also have orientation information of the airplane) but somehow the ellipsoid model fails to do it appropriately. I found another tool that transforms the coordinates correctly and I could see the terrain: so the problem seems to be solved for now. But I cannot see how & why osgdem transforms it correctly but the ellipsoid model fails to do it. So I still would be glad if someone could tell me what the problem is.. deniz ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=35197#35197 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
