#VRML V2.0 utf8 # # Filename: GeoLocation.wrl # # Author: # Martin Reddy, SRI International - 21 August 1999. # # Purpose: # This file contains the definition for a new node that aims to # provide support for geographic coordinate systems within VRML. # The goal is to be able to take any arbitrary VRML context and # georeference it, i.e. place it at a specific point on the planet. # # The implementation is written in Java because we need access to # double precision support. You will therefore require a VRML # browser that supports Java in the Script node. # # This node is part of the GeoVRML 1.0 sample implementation. # For information, refer to http://www.geovrml.org/1.0/ # # License: # The contents of this file are subject to GeoVRML Public License # Version 1.0 (the "License"); you may not use this file except in # compliance with the License.
