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.
