== Introduction ==

All objects in the 3D scene are objects, with fixed or dynamic position. An visual_object can be positioned in latitude, longitude and altitude, as well in rotations along all three axis.
By assigning a 3D modell to an visual_object, the Model is visible in the scene and can be freely positioned.

Basically, a visual_object is a simple Matrixtransform which has the geometry as childnode.

visual_object provides the following convenience variables / functions for simple usage of objects in osgVisual:
 * positioning in lat, lon, alt (position)
 * rotating along all 3 object axis (attitude)
 * scaling along all 3 axis
 * loading/unloading 3D geometry
 * setting geometry offset, if 3D model has wrong axis orientation
 * camera translation offset (on node attached camera manipulator)
 * camera attitude offset (on node attached camera manipulator)
 * setting/clearing label (todo)
