\class SoCoordinate3 SoCoordinate3.h Inventor/nodes/SoCoordinate3.h
\brief The SoCoordinate3 class is a node for providing coordinates to shape nodes.
\ingroup 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 \e replace the coordinates
already present in the state (if any).
<b>FILE FORMAT/DEFAULTS:</b>
\code
Coordinate3 {
point 0 0 0
}
\endcode
