NAME
SoGeoLocation
SYNOPSIS
#include <Inventor/nodes/SoGeoLocation.h> Inherits SoTransformation.
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. - See also:
- SoGeoOrigin
- Since:
- Coin 2.5

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}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {SoGroup * group = (SoGroup *)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.
- References SoAction::getState().
- void SoGeoLocation::doAction (SoAction * action) [virtual]
- This function performs the typical operation of a node for any action.
- Reimplemented from SoNode.
- Referenced by callback(), and pick().
- 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.
- References doAction().
- 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.
- References SoAction::getState().
- 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.
- References doAction().
- 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.
