Geodetic Pivot
A geodetic pivot object is an abstract object that contains an ellipsoid with a pivot point. By using geodetic pivot you can place objects on the scene on the corresponding places in the real world.
Geodetic pivot helps to place world objects on their real world positions (latitude, longitude and altitude) by curving a plane with objects on it. Pivot converts real geodetic data to Cartesian and simultaneously "curves" objects to simulate the contorted Earth's surface.
Geodetic pivot works with:
 ObjectTerrain
 ObjectTerrainGlobal
 ObjectWaterGlobal
 ObjectCloudLayer
 ObjectSky
 ObjectMeshStatic
 ObjectGrass
 ObjectMeshClutter
 WorldClutter
 Mesh Decals

Adding a Geodetic Pivot#
To add a static mesh to the scene via UnigineEditor do the following:
 Run the project with UnigineEditor.
 On the Menu bar, click Create > Geodetics > Pivot.
 Place the pivot somewhere in the world.
Setting Up a Geodetic Pivot#
After adding the Geodetic Pivot on the scene, set up the parameters located in the Geodetic Pivot tab of the Parameters window.
 Location settings. The geodetic location on the Earth of the pivot point. It is specified by 3 components:
 Latitude is the north–south position in degrees of a point on the Earth's surface. For example, Tomsk city latitude is 56.4977100. 0 value means equator, 90 value means the North Pole, 90 means the South Pole.
 Longitude is the eastwest position in degrees of a point on the Earth's surface. For example, Tomsk city longitude is 84.9743700. 0 value means a prime meridian (Greenwich). This field supports two ranges: from 180 to 180 and from 0 to 360.
 Altitude is the height above sea level of a location. For example, Tomsk city altitude is 117 meters.
 Coordinates
 X  Y  Z (Local) disables the binding to geocoordinates. Geodetic Pivot can be placed everywhere.
 East  North  Up (EarthCentric) places Geodetic Pivot to the world ECF position with ENU orientation according to given latitude / longitude / altitude. The Geodetic Pivot position is blocked.
 Flat geopositioning mode of the Geodetic Pivot. This mode should be used, when it is necessary only to set node positions via geo coordinates (latitude, longitude, altitude) without curving the terrain, clouds, etc.
 Ellipsoid settings.
 Reference is a mathematically defined ellipsoid that approximates the surface of the planet. We offer popular geocentric reference ellipsoids: WGS84, GRS80, Airy 1830, etc.
Working with Geodetic Pivot#
After adding and setting up the Geodetic Pivot, you can simply add objects to "curve" them:
 Choose the necessary nodes (static meshes, grass, clutters, etc.) in the Nodes window and set them as children of the Geodetic Pivot.
 Specify the necessary settings of the Geodetic Pivot.
 The update will be performed automatically.
As you add a node as a child to the Geodetic Pivot its geo position coordinates (latitude, longitude and altitude) are displayed in the Common group of the Nodes tab:
Geo Position  Specifies the geo position coordinates for the node (latitude, longitude and altitude). 

By default only the following objects are curved by the Geodetic Pivot:
As for static meshes, mesh decals and billboards, sometimes you might just want to set their positions in real world coordinates an leave their geometry as is, but in some cases they should be curved (e.g., large static meshes, or roads represented as mesh decals). For this purpose you should use the following two buttons: 

Make Curved  Curves the geometry of the object according to the specified settings. 
Make Flat  Returns the geometry of the object back to normal (uncurved) state according to the specified settings..
