Detailed Description
The SoNode class is the base class for nodes used in scene graphs.
Coin is a retained mode 3D visualization library (built on top of the immediate mode OpenGL library). 'Retained mode' means that instead of passing commands to draw graphics primitives directly to the renderer, you build up data structures which are rendered by the library on demand.
The node classes are the main 'primitive' for building these data structures. In Coin, you build tree hierarchies made up of different node types: group nodes (for the tree structure layout of the other nodes), appearance nodes (for setting up materials, textures, etc), shape nodes (for the actual geometry), and nodes for lighting and camera positioning.
One common issue with newcomers to the API is that you should not and cannot use the C++ delete operator on nodes -- the destructor is protected. This is because node instances are using a common technique for memory resource handling called 'reference counting'. Nodes are deleted (actually, they delete themselves) when their unref() method is called and the reference count goes to zero.
One important side-effect of this is that SoNode-derived classes should not be statically allocated, neither in static module memory nor on functions stack frames. SoNode-derived classes must always be allocated dynamically from the memory heap with the new operator (or else the scheme with self-destruction upon dereferencing to 0 would not work).
Usually application programmers won't manually ref() and unref() nodes a lot, because you pass the nodes directly to SoGroup::addChild() or So@Gui@Viewer::setSceneGraph() or something similar. These functions will ref() the nodes they are passed, and unref() them when they are finished with them.
Make sure you do ref() nodes that you keep pointers to so they aren't accidentally deleted prematurely due to an unref() call from within the library itself. If you haven't manually called ref() on a top level root node, it will then be deleted automatically. This code shows how to do it:
SoSeparator * root = new SoSeparator; // root's refcount starts out at zero root->addChild(foo_node); // foo_node refcount is increased by 1 root->addChild(bar_node); // bar_node refcount +1 // increase refcount before passing it to setScenegraph(), to avoid // premature destruction root->ref(); myviewer->setSceneGraph(root); // root's refcount +1, is now 2 // [misc visualization and processing] // myviewer will let go of its reference to the root node, thereby // decreasing its reference count by 1 myviewer->setSceneGraph(NULL); // root's refcount goes from +1 to 0, and it will self-destruct controllably root->unref(); // avoid dangling pointer, in case "root" is attempted used again // (not really necessary, but good for smoking out bugs early) root = NULL;
For full information and tutorial-style introductions to all API issues, see the 'Inventor Mentor: Programming Object-Oriented 3D Graphics with Open Inventor' (ISBN 0-201-62495-8). It has detailed explanations on all the basic principles involved.
See specifically the section 'References and Deletion' in Chapter 3 to learn about the reference counting techniques.
Often when using the Coin library, one is interested in making extensions to it. Of particular interest is setting up extension nodes, which are then traversed, rendered and otherwise used by the rest of the library as any internal node.
The Coin header file Inventor/nodes/SoSubNode.h includes a set of convenience macros for quick and easy construction of extension nodes. Here's a complete snippet of code which shows how to set up a skeleton framework for an extension node class:
#include <Inventor/nodes/SoWWWInline.h>
class MyWWWInline : public SoWWWInline {
SO_NODE_HEADER(MyWWWInline);
public:
static void initClass(void);
MyWWWInline(void);
protected:
virtual ~MyWWWInline();
};
SO_NODE_SOURCE(MyWWWInline);
MyWWWInline::MyWWWInline(void)
{
SO_NODE_CONSTRUCTOR(MyWWWInline);
}
MyWWWInline::~MyWWWInline()
{
}
void
MyWWWInline::initClass(void)
{
SO_NODE_INIT_CLASS(MyWWWInline, SoWWWInline, "SoWWWInline");
}
int
main(int argc, char ** argv)
{
SoDB::init();
MyWWWInline::initClass();
// [...]
return 0;
}You can then override for instance the GLRender() method to have your new class render OpenGL geometry different from its superclass.
For extending the Coin library with your own classes, we strongly recommend that you make yourself acquainted with the excellent The Inventor Toolmaker book (ISBN 0-201-62493-1), which describes the tasks involved in detail. This book was written by the original SGI Inventor designers and explains many of the underlying design ideas, as well as having lots of hands-on examples on how to extend the Coin toolkit in ways that are true to the fundamental design ideas. (The Inventor Toolmaker is also available at SGI's online library, at no cost. See Download The Inventor Toolmaker.) Reading the source code of the built-in classes in Coin should also prove very helpful.
For information about dynamic loading of extension nodes, see the documentation of SoType::fromName().

Member Function Documentation
void SoNode::setOverride (const SbBool state)
Set the override flag.
If this flag is TRUE, the field values of this node will override the field values of other nodes of the same type during scene graph traversal.
A common application for 'override nodes' is to place them at the top of the tree as a convenient way to force e.g. a common draw style on the complete tree.
The override flag does not exist in the Inventor file format. This flag is in other words not persistent, and must be programmatically set. The rationale for this flag is for viewers to be able to control rendering style of the 3D models, so it would look stupid if some parts of certain models suddenly didn't adhere to the viewer mode.
SbBool SoNode::isOverride (void) const
Return status of override flag.
- See also
setOverride()
uint32_t SoNode::getCompatibilityTypes (const SoType & nodetype) [static]
Get the node compatibility mask for node type nodetype. The return value will be a bit mask of SoNode::NodeType flags, containing one or several flags.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
- Since
Coin 2.0
void SoNode::setNodeType (const NodeType type)
Sets the node type for this node to type. Since some nodes should be handled differently in VRML1 vs. Inventor, this should be used to get correct behavior for those cases. The default node type is INVENTOR.
This method is an extension versus the Open Inventor API.
- See also
getNodeType()
SoNode::NodeType SoNode::getNodeType (void) const
Returns the node type set for this node.
This method is an extension versus the Open Inventor API.
- See also
setNodeType()
SoNode * SoNode::copy (SbBool copyconnections = FALSE) const [virtual]
Make a duplicate of this node and return a pointer to the duplicate.
If this node is a group node, children are also copied and we return a pointer to the root of a full copy of the subgraph rooted here.
If copyconnections is TRUE, we also copy the connections to fields within this node (and ditto for any children and children's children etc.).
Note that this function has been made virtual in Coin, which is not the case in the original Open Inventor API. We may change this method back into being non-virtual again for major Coin versions after this, as it was made virtual more or less by mistake. So please don't write application code that depends on SoNode::copy() being virtual.
The reason this method should not be virtual is because this is not the function the application programmer should override in extension nodes if she needs some special behavior during a copy operation (like copying the value of internal data not exposed as fields).
For that purpose, override the copyContents() method. Your overridden copyContents() method should then both copy internal data as well as calling the parent superclass' copyContents() method for automatically handling of fields and other common data.
SbBool SoNode::affectsState (void) const [virtual]
Returns TRUE if the node could have any effect on the state during traversal.
If it returns FALSE, no data in the traversal state will change from the pre-traversal state to the post-traversal state. The SoSeparator node will for instance return FALSE, as it pushes and pops the state before and after traversal of its children. All SoShape nodes will also return FALSE, as just pushing out geometry data to the rendering engine won't affect the actual rendering state.
The default method returns TRUE, on a 'better safe than sorry' philosophy.

Called from SoHandleEventAction to notify a node when it looses status as the node where events are sent.
Reimplemented in SoDragger.
void SoNode::startNotify (void) [virtual]

At the end of a notification sequence, all 'immediate' sensors (i.e. sensors set up with a zero priority) are triggered.
Reimplemented from SoBase.
void SoNode::notify (SoNotList * l) [virtual]

SbUniqueId SoNode::getNodeId (void) const
This returns the node's current unique identification number. It is unlikely that application programmers will ever need use this method from client application code, unless working with extensions to the core library (and probably not even then).
The id number is only valid for as long as the node is kept unchanged -- upon any kind of change the internal id will be updated (in the notify() method), and the old id number forgotten.
The technique described above plays an important role in the way internal scene graph caches are set up and invalidated.

SoNode::getNextNodeId()
SoChildList * SoNode::getChildren (void) const [virtual]
Returns list of children for this node.
Reimplemented in SoClipPlaneManip, SoDirectionalLightManip, SoPointLightManip, SoSpotLightManip, SoTransformManip, SoBaseKit, SoNodeKitListPart, SoFile, SoGroup, SoWWWInline, SoVRMLAppearance, SoVRMLGeometry, SoVRMLInline, SoVRMLLOD, SoVRMLParent, SoVRMLShape, SoVRMLSwitch, and SoVRMLText.
void SoNode::writeInstance (SoOutput * out) [virtual]
Writes all the fields contained in this instance to the output stream within out.
This method is solely called from the write methods of fields.
Either from SoField if the write is done because of a field-to-field connection, or from one of the fields which may actually write SoFieldContainer instances, i.e. SoSFNode, SoMFNode, SoSFEngine, SoMFEngine, SoSFPath and SoMFPath.
This method, in addition to the ordinary write() method of SoNode, needs to be present since the fields don't have a write action instance in their writeValue() method, and writeInstance() will create a new SoWriteAction and call continueToApply() on it.
Reimplemented from SoFieldContainer.
Reimplemented in SoNodeEngine.
SoNode * SoNode::addToCopyDict (void) const [virtual]
Add a copy of this node and (recursively) all children to the copy dictionary of SoFieldContainer if this has not already been done.
Used internally during copy operations.
Reimplemented in SoBaseKit.
void SoNode::copyContents (const SoFieldContainer * from, SbBool copyconnections) [virtual]
Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE.
This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically.
For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:
SoNode * mynewnode = templatenode->copy();
The same also goes for engines.
Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:
void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
SbBool copyconnections)
{
// let parent superclasses do their thing (copy fields, copy
// instance name, etc.)
SoNode::copyContents(from, copyconnections);
// [..then copy internal data..]
}Reimplemented from SoFieldContainer.

Note: default implementation just returns this pointer, SoNode and SoEngine overrides this method to return the pointer to the actual copy.
Reimplemented from SoFieldContainer.

SbBool SoNode::readInstance (SoInput * in, unsigned short flags) [protected], [virtual]
This method is mainly intended for internal use during file import operations.
It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type.
TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE.
flags is used internally during binary import when reading user extension nodes, group nodes or engines.
