GeoPositionInterpolator
GeoPositionInterpolator animates objects within a geographic coordinate system. GeoPositionInterpolator can contain a GeoOrigin node.
The GeoPositionInterpolator node belongs to the Geospatial component and its container field is children. It is available since X3D version 3.0 or later.
Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFNode [ ] geoOrigin NULL [GeoOrigin] (deprecated)
Field geoOrigin.
MFString [ ] geoSystem [ "GD", "WE" ]
Identifies spatial reference frame: Geodetic (GD), Geocentric (GC), Universal Transverse Mercator (UTM). Supported values: "GD" "UTM" or "GC" followed by additional quoted string parameters as appropriate for the type.
Warning
Deprecated values are GDC (use GD) and GCC (use GC).

SFFloat [in] set_fraction (-∞,∞)
Set_fraction selects input key for corresponding keyValue output.
MFFloat [in, out] key [ ] (-∞,∞)
Definition parameters for linear-interpolation function time intervals, in increasing order and corresponding to keyValues.
Warning
Number of keys must match number of keyValues!
MFVec3d [in, out] keyValue [ ]
Output values for linear interpolation, each corresponding to time-fraction keys.
Warning
Number of keys must match number of keyValues!
SFVec3d [out] value_changed
Linearly interpolated output value determined by current key time and corresponding keyValue pair.
SFVec3d [out] geovalue_changed
Interpolated coordinate in the geographic coordinate system specified by geoSystem
