const std::string& makVrv::DtCoordinateSystem::type ( ) const

The coordinate system type is determined by the active coordinate converter.

bool makVrv::DtCoordinateSystem::isGeocentric ( ) const

const DtFlatEarthCoordinateConverter* makVrv::DtCoordinateSystem::flatEarthConverter ( ) const
void makVrv::DtCoordinateSystem::setUseTopoForFlatEarthVectorConversion ( bool  flag)

We used to use a topo system to convert flat earth vectors. Now we find the point at the end of the vector, convert start and end points, and subtract for a more accurate result. However, when receiving data from a sim using the old method (including older versions of VR-Forces and DI-Guy) user's may want to revert to the old scheme.

const DtMapDatum& makVrv::DtCoordinateSystem::datum ( ) const

Return our map datum.

void makVrv::DtCoordinateSystem::setDatum ( const DtMapDatum &  datum)

Set our map datum This function should be called rather than calling DtUseMapDatum to ensure that our converters can be kept in sync.

void makVrv::DtCoordinateSystem::netToLocalPos ( const DtVector &  netpos,
DtVector &  localpos
