Detailed Description

VSG extension Geographic coordinates node.

The SoGeoCoordinate node allows applications to build geometry using geographic coordinates

The SoGeoCoordinate node specifies a list of coordinates in a spatial reference frame. It can be used in place of an SoCoordinate3 node. 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 world where all coordinates are specified in terms of latitude, longitude, and elevation.
