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

SoType SoGeoLocation::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoTransformation.

SoType SoGeoLocation::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoTransformation.

const SoFieldData ** SoGeoLocation::getFieldDataPtr (void) [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Reimplemented from SoTransformation.

const SoFieldData * SoGeoLocation::getFieldData (void) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoTransformation.

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.
