Hi, okay, after some examples debugging i think i got it: a CoordinateSystem is a user added node, which provides methods that allow to setup a matrix with lat/lon instead of cartesian coordinates.
on flat environments, there is no need to setup a CoordinateSystem. when getCoordinateFrame(pos) is called in such a case, a matrix with rotation of a default coordinatesystem (001, 010, 001) and translation of pos is returned. if that is somehow correct, i have another question: is it right that, in case of an ellipsoid CoordinateSystem (like in the example "osgsimulation.exe") the rotation-part of the resulting-matrix is depended of the current position? Thank you!
