Detailed Description
Geographic coordinates node.
The SoVRMLGeoCoordinate node allows applications to build geometry using geographic coordinates
VRML X3D SPECIFICATION
- This section describes the expected behavior of the node in a conforming X3D / VRML97 browser application. In some cases, the application is responsible for implementing portions of the expected behavior. Open Inventor viewer classes and IVF classes implement some of the application behaviors.
This section may reference portions of the X3D specification that are not present in this help file. The complete X3D spec is available at http://www.web3d.org .
The SoVRMLGeoCoordinate node specifies a list of coordinates in a spatial reference frame. It is used in the coord field of vertex-based geometry nodes including SoVRMLIndexedFaceSet, SoVRMLIndexedLineSet, and SoVRMLPointSet. The geoOrigin field is used to specify a local coordinate frame for extended precision as described in 25.2.5 Dealing with high-precision coordinates. The geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The point array is used to contain the actual geospatial coordinates and should be provided in a format consistent with that specified for the particular geoSystem (see above). The geospatial coordinates are transparently transformed into a geocentric, curved-earth representation. For example, this would allow a geographer to create a X3D world where all coordinates are specified in terms of latitude, longitude, and elevation.

EVENTS
- Deprecated:
-
Deprecated since Open Inventor 9500
The VRML API is no longer supported. See section http://oivdoc95.vsg3d.com/content/compatibility-notes-4#Deprecation of the Reference Manual. - GC: Earth-fixed Geocentric with respect to the WGS84 ellipsoid.
- GD: Geodetic spatial reference frame.
An optional second string may be used to specify the ellipsoid using one of the ellipsoid codes that are defined in X3D. If no ellipsoid is specified, then "WE" is assumed (the WGS84 ellipsoid). - UTM: Universal Transverse Mercator
One further required argument must be supplied for UTM in order to specify the zone number (1..60). This is given in the form "Z<n>", where "<n>" is the zone number. An optional argument of "S" may be supplied in order to specify that the coordinates are in the southern hemisphere (otherwise, northern hemisphere will be assumed). - Inventor/geo/SoVRMLGeoCoordinate.h
