示例1: visitPoint
bool visitPoint( GeoPoint& p )
{
bool ok = true;
// pull it out of the source reference frame:
p.set( p * src_rf );
// reproject it:
if ( handle )
ok = OCTTransform( handle, 1, &p.x(), &p.y(), &p.z() ) != 0;
// push it into the new reference frame:
p.set( p * to_srs->getReferenceFrame() );
p = p.getDim() == 2? GeoPoint( p.x(), p.y(), to_srs ) : GeoPoint( p.x(), p.y(), p.z(), to_srs );
return ok;
}示例2:
bool
MapInfo::worldPointToMapPoint( const osg::Vec3d& input, GeoPoint& output ) const
{

bool ok = _profile->getSRS()->transformFromWorld(input, temp);
if ( ok )
