:) I think you misunderstood me. I have been searching all forum. The terrain (is not whole earth) database was created correctly using osgdem with Terrain and geocentric parameters. Also camera position is computed correctly and I can easily track may object using orbit manipulator. But, If I use object transformation in ECEF coordinate system, My object does not move smoothly. It moves up and down little bit.
If I use local coordinates that are converted from lats/long/height according to an origin point, object moves correctly. Also I am not using delta3d directly and the problem is not related to GeoCoordinate. If I transform terrain or root scene to this origin point, how can I calculate object transformation without terrain-object correlation problem ?
