GeodeticPivot Class
Inherits: | Node |
This class is used to create and modify a geodetic pivot object that is used to place world objects on their real world positions (latitude, longitude and altitude).
Geodetic pivot object works only in Sim version of Unigine Engine. In other editions it's equivalent to NodeDummy.
GeodeticPivot Class
Members
static GeodeticPivot()
GeodeticPivot constructor. Creates a GeodeticPivot instance with the default settings:- The origin is set to dvec3(0.0,0.0,0.0).
- The size of the curving region is 2048000×2048000 km.
- The resolution of the region texture is 2048.
GeodeticPivot cast(Node node)
Casts a GeodeticPivot out of the Node instance.Arguments
- Node node - Node instance.
Return value
GeodeticPivot instance.void setEllipsoid(Ellipsoid ellipsoid)
Sets an Ellipsoid for the GeodeticPivot object.Arguments
- Ellipsoid ellipsoid - An Ellipsoid.
void setOrigin(dvec3 origin)
Sets a new position (latitude, longitude and altitude) on the ellipsoid.// the GeodeticPivot will use WGS84 reference ellipsoid by default
GeodeticPivot pivot = new GeodeticPivot();
// update the origin
dvec3 new_york_origin = dvec3(40.71427,-74.00597,57.0);
pivot.setOrigin(new_york_origin);
ObjectMeshStatic flat_new_york_ground = new ObjectMeshStatic("flat_new_york_ground.mesh");
pivot.addChild(flat_new_york_ground); // the mesh will be bent once ObjectMeshStatic become a child of GeodeticPivot
Arguments
- dvec3 origin - Origin vector in ellipsoid coordinates.
dvec3 getOrigin()
Returns the position (latitude, longitude and altitude) on the ellipsoid.Return value
Origin vector in ellipsoid coordinates.void setOriginBasis(int basis)
Arguments
- int basis
int getOriginBasis()
Returns the origin basis set for the GeodeticPivot object:- If GEODETIC_PIVOT_ORIGIN_BASIS_LOCAL is set, the binding to geo-coordinates is disabled. GeodeticPivot can be placed everywhere.
- If GEODETIC_PIVOT_ORIGIN_BASIS_ENU is set, GeodeticPivot is placed to the world ECF position with ENU (East - North - Up) orientation according to the given latitude / longitude / altitude. The GeodeticPivot position is blocked.
Return value
int type()
Returns the type of the object.Return value
GeodeticPivot type identifier.int GEODETIC_PIVOT_ORIGIN_BASIS_ENU
Description
The origin basis East - North - Up (Earth-Centric) is used for the GeodeticPivot object. It is used to place the pivot to the world ECF position with ENU orientation according to latitude / longitude / altitude. The position of the GeodeticPivot object is blocked when this basis is used.int GEODETIC_PIVOT_ORIGIN_BASIS_LOCAL
Description
The local (X - Y - Z) origin basis is used for the GeodeticPivot object. The pivot doesn't bind to geo-coordinates and can be placed anywhere.int GEODETIC_PIVOT_STATUS_CURVED
Description
The status of the child nodes of the GeodeticPivot object is Curved (nodes' geometry is "curved" to simulate the contorted Earth's surface).int GEODETIC_PIVOT_STATUS_FLAT
Description
The status of the child nodes of the GeodeticPivot object is Flat (nodes' geometry isn't "curved" to simulate the contorted Earth's surface).int GEODETIC_PIVOT_STATUS_NEED_UPDATE
Description
The status of the child nodes of the GeodeticPivot object is Require Update.Last update: 2017-07-03
