Detailed DescriptionThe SoVRMLCoordinate class is used to define 3D coordinates for shapes. The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:
Coordinate {
exposedField MFVec3f point [] # (-inf, inf)
}
This node defines a set of 3D coordinates to be used in the coord field of vertex-based geometry nodes including SoVRMLIndexedFaceSet, SoVRMLIndexedLineSet, and SoVRMLPointSet.

Member Function Documentation
SoType SoVRMLCoordinate::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. Implements SoBase.
const SoFieldData * SoVRMLCoordinate::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 SoFieldContainer.
void SoVRMLCoordinate::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action. Reimplemented from SoNode. References SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), and point. Referenced by callback(), getBoundingBox(), GLRender(), and pick().
void SoVRMLCoordinate::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 doAction(), SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), point, SoBase::staticDataLock(), and SoBase::staticDataUnlock().
void SoVRMLCoordinate::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. References doAction().
void SoVRMLCoordinate::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 SoVRMLCoordinate::pick (SoPickAction * action) [virtual]Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoNode. References doAction().
