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
can not 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
function’s 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 de-referencing 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*ViewersetSceneGraph() 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 it’s reference to the root node, thereby
// decreasing it’s referencecount 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 it’s 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,
aswell 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 sourcecode of
the built-in classes in Coin should also provide very helpful.
For information about dynamic loading of extension nodes, see the
documentation of SoType::fromName().

Constructor & Destructor Documentation
SoNode::SoNode (void) [protected] Default constructor, initializes node

SoNode::~SoNode () [protected, virtual] Destructor.
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 applicaton for ’override nodes’ is to place them at the top of
the tree as a convenient way to force e.g. a common drawstyle 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 = 0) 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 aswell 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.

void SoNode::search (SoSearchAction * action) [virtual] Action method for
SoSearchAction.
Compares the search criteria from the action to see if this node is a
match. Searching is done by matching up all criteria set up in the
SoSearchAction -- if any of the requested criteria is a miss, the
search is not deemed successful for the node.

uint32_t 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 fom 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 scenegraph caches are set up and invalidated.

children for this node.

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 scenegraph references if copyconnections
is FALSE.
This is the protected method that should be overridden by extension
node / engine / dragger / whatever subclasses which needs 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 it’s 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 etc)
SoNode::copyContents(from, copyconnections);
// [..then copy internal data..]
}

copy.

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 / persistant
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.
