Here's some code I use, I'm still not quite sure what you are asking though.
void CViewScenario::convertLLHtoLocal(double Lat_deg, double Long_deg,
double Alt, double &x, double &y, double &z)
{
double ecefx, ecefy, ecefz;
mEllipse->convertLatLongHeightToXYZ(
osg::DegreesToRadians((double)Lat_deg),
osg::DegreesToRadians((double)Long_deg),
Alt,
ecefx,ecefy,ecefz);
osg::Vec3d ecefpos(ecefx,ecefy,ecefz);
osg::Vec3d localpos = mECEFtoLocalMatrix.preMult(ecefpos);
x = localpos.x();
y = localpos.y();
z = localpos.z();
}
Also see here:
http://www.colorado.edu/geography/gcraft/notes/coordsys/coordsys.html
The osg code follows these explanations.
