Detailed Description

       The SoGeoLocation class is used to georeference the following nodes.

       FILE FORMAT/DEFAULTS:

           GeoLocation {
             geoSystem ['GD', 'WE']
             geoCoords 0 0 0
           }

       This node specifies an absolute geographic coordinate system for the following nodes. When
       rendering (or applying other actions), Coin will add a transformation which transforms the
       geometry into the SoGeoOrigin coordinate system. All objects will be rotated to make the
       local Z axis point up from the ground (at the specified geo-location), the Y axis will
       point towards the north pole, and the X axis is found using the right hand rule.

Member Function Documentation

   void SoGeoLocation::initClass (void) [static] Sets up initialization for data common to all
       instances of this class, like submitting necessary information to the Coin type system.
       Reimplemented from SoTransformation.

   void SoGeoLocation::doAction (SoAction *action) [virtual] This function performs the typical
       operation of a node for any action.
       Reimplemented from SoNode.

   void SoGeoLocation::callback (SoCallbackAction *action) [virtual] Action method for
       SoCallbackAction.
       Simply updates the state according to how the node behaves for the render action, so the
       application programmer can use the SoCallbackAction for extracting information about the
       scene graph.

       Reimplemented from SoNode.

   void SoGeoLocation::GLRender (SoGLRenderAction *action) [virtual] Action method for the
       SoGLRenderAction.
       This is called during rendering traversals. Nodes influencing the rendering state in any
       way or who wants to throw geometry primitives at OpenGL overrides this method.

       Reimplemented from SoNode.

   void SoGeoLocation::getBoundingBox (SoGetBoundingBoxAction *action) [virtual] Action method
       for the SoGetBoundingBoxAction.
       Calculates bounding box and center coordinates for node and modifies the values of the
       action to encompass the bounding box for this node and to shift the center point for the
       scene more towards the one for this node.

       Nodes influencing how geometry nodes calculates their bounding box also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.

   void SoGeoLocation::getMatrix (SoGetMatrixAction *action) [virtual] Action method for
       SoGetMatrixAction.
       Updates action by accumulating with the transformation matrix of this node (if any).

       Reimplemented from SoNode.

   void SoGeoLocation::pick (SoPickAction *action) [virtual] Action method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

   void SoGeoLocation::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual] Action
       method for the SoGetPrimitiveCountAction.
       Calculates the number of triangle, line segment and point primitives for the node and adds
       these to the counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count also overrides this
       method to change the relevant state variables.

       Reimplemented from SoNode.
