NAME
SoCoordinate3 -
The SoCoordinate3 class is a node for providing coordinates to shape
nodes.
When encountering nodes of this type during traversal, the coordinates
it contains will be put on the state stack for later use by shape nodes
of types which needs coordinate sets (like SoFaceSet nodes or
SoPointSet nodes).

Detailed Description
The SoCoordinate3 class is a node for providing coordinates to shape
nodes.
When encountering nodes of this type during traversal, the coordinates
it contains will be put on the state stack for later use by shape nodes
of types which needs coordinate sets (like SoFaceSet nodes or
SoPointSet nodes).
Note that an SoCoordinate3 node will replace the coordinates already
present in the state (if any).

Member Function Documentation
void SoCoordinate3::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 SoNode.
void SoCoordinate3::doAction (SoAction * action) [virtual] This function
performs the typical operation of a node for any action.
Reimplemented from SoNode.
void SoCoordinate3::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 SoCoordinate3::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 SoCoordinate3::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 SoCoordinate3::pick (SoPickAction * action) [virtual] Action method
for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
void SoCoordinate3::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.
