visualization library (built on top of the \fIimmediate\fP \fImode\fP 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 \fIon\fP \fIdemand\fP\&. 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\&. .PP 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 \fBunref()\fP method is called and the reference count goes to zero\&. .PP One important side-effect of this is that SoNode-derived classes should \fInot\fP be statically allocated, neither in static module memory nor on function's stack-frames\&. SoNode-derived classes must \fIalways\fP be allocated dynamically from the memory heap with the \fCnew\fP operator (or else the scheme with self-destruction upon de-referencing to 0 would not work)\&. .PP Usually application programmers won't manually \fBref()\fP and \fBunref()\fP nodes a lot, because you pass the nodes directly to \fBSoGroup::addChild()\fP or So*Viewer::setSceneGraph() or something similar\&. These functions will \fBref()\fP the nodes they are passed, and \fBunref()\fP them when they are finished with them\&. .PP Make sure you do \fBref()\fP nodes that you keep pointers to so they aren't accidentally deleted prematurely due to an \fBunref()\fP call from within the library itself\&. If you haven't manually called \fBref()\fP on a top-level root node, it will then be deleted automatically\&. This code shows how to do it: .PP .PP .nf 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; .fi .PP .PP 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\&. .PP See specifically the section 'References and Deletion' in Chapter 3 to learn about the reference counting techniques\&. .PP 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\&. .PP The Coin header file \fBInventor/nodes/SoSubNode\&.h\fP 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: .PP .PP .nf #include 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; } .fi .PP .PP You can then override for instance the \fBGLRender()\fP method to have your new class render OpenGL geometry different from it's superclass\&. .PP 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 \fCDownload The Inventor Toolmaker\fP\&.) Reading the sourcecode of the built-in classes in Coin should also provide very helpful\&. .PP For information about dynamic loading of extension nodes, see the documentation of \fBSoType::fromName()\fP\&. .SH "Member Enumeration Documentation" .PP .SS "enum \fBSoNode::NodeType\fP" Used to store node type\&. .PP \fBEnumerator\fP .in +1c .TP \fB\fIINVENTOR \fP\fP Specifies Inventor node type\&. .TP \fB\fIVRML1 \fP\fP Node is VRML V1\&.0 compatible\&. .TP \fB\fIVRML2 \fP\fP Node is from the VRML V2\&.0 specification\&. .TP \fB\fIINVENTOR_1 \fP\fP Node was part of SGI Inventor version 1\&. .TP \fB\fIINVENTOR_2_0 \fP\fP Node was part of SGI Inventor version 2\&.0\&. .TP \fB\fIINVENTOR_2_1 \fP\fP Node was introduced with SGI / TGS Inventor version 2\&.1\&. .TP \fB\fIINVENTOR_2_5 \fP\fP Node was introduced with TGS Inventor version 2\&.5\&. .TP \fB\fIINVENTOR_2_6 \fP\fP Node was introduced with TGS Inventor version 2\&.6\&. .TP \fB\fICOIN_1_0 \fP\fP Node was part of Coin version 1\&. .TP \fB\fICOIN_2_0 \fP\fP Node was introduced with Coin 2\&.0\&. .TP \fB\fIEXTENSION \fP\fP Node is a client code extension\&. .SH "Constructor & Destructor Documentation" .PP .SS "SoNode::SoNode (void)\fC [protected]\fP" Default constructor, initializes node instance\&. .SS "SoNode::~SoNode ()\fC [protected]\fP, \fC [virtual]\fP" Destructor\&. .SH "Member Function Documentation" .PP .SS "void SoNode::setOverride (const SbBoolstate)" Set the override flag\&. .PP If this flag is \fCTRUE\fP, the field values of this node will override the field values of other nodes of the same type during scene graph traversal\&. .PP 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\&. .PP 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\&. .SS "SbBool SoNode::isOverride (void) const" Return status of override flag\&. .PP \fBSee also:\fP .RS 4 \fBsetOverride()\fP .RE .PP .SS "uint32_t SoNode::getCompatibilityTypes (const \fBSoType\fP &nodetype)\fC [static]\fP" Get the node compatibility mask for node type \fInodetype\fP\&. The return value will be a bit mask of \fBSoNode::NodeType\fP flags, containing one or several flags\&. .PP This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2\&.1 API\&. .PP \fBSince:\fP .RS 4 Coin 2\&.0 .RE .PP .SS "void SoNode::setNodeType (const \fBNodeType\fPtype)" Sets the node type for this node to \fItype\fP\&. 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\&. .PP This method is an extension versus the Open Inventor API\&. .PP \fBSee also:\fP .RS 4 \fBgetNodeType()\fP .RE .PP .SS "\fBSoNode::NodeType\fP SoNode::getNodeType (void) const" Returns the node type set for this node\&. .PP This method is an extension versus the Open Inventor API\&. .PP \fBSee also:\fP .RS 4 \fBsetNodeType()\fP .RE .PP .SS "\fBSoNode\fP * SoNode::copy (SbBoolcopyconnections = \fCFALSE\fP) const\fC [virtual]\fP" Make a duplicate of this node and return a pointer to the duplicate\&. .PP 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\&. .PP If \fIcopyconnections\fP is \fCTRUE\fP, we also copy the connections to fields within this node (and ditto for any children and children's children etc)\&. .PP 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 \fBSoNode::copy()\fP being virtual\&. .PP The reason this method should not be virtual is because this is \fInot\fP 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)\&. .PP For that purpose, override the \fBcopyContents()\fP method\&. Your overridden \fBcopyContents()\fP method should then \fIboth\fP copy internal data aswell as calling the parent superclass' \fBcopyContents()\fP method for automatically handling of fields and other common data\&. .SS "SbBool SoNode::affectsState (void) const\fC [virtual]\fP" Returns \fCTRUE\fP if the node could have any effect on the state during traversal\&. .PP If it returns \fCFALSE\fP, no data in the traversal-state will change from the pre-traversal state to the post-traversal state\&. The \fBSoSeparator\fP node will for instance return \fCFALSE\fP, as it pushes and pops the state before and after traversal of its children\&. All \fBSoShape\fP nodes will also return \fCFALSE\fP, as just pushing out geometry data to the rendering engine won't affect the actual rendering state\&. .PP The default method returns \fCTRUE\fP, on a 'better safe than sorry' philosophy\&. .PP Reimplemented in \fBSoSeparator\fP, \fBSoNodeKitListPart\fP, \fBSoShape\fP, \fBSoVRMLShape\fP, \fBSoVRMLSwitch\fP, \fBSoArray\fP, \fBSoVRMLProximitySensor\fP, \fBSoVRMLTouchSensor\fP, \fBSoSwitch\fP, \fBSoVRMLLOD\fP, \fBSoSceneKit\fP, \fBSoVRMLParent\fP, and \fBSoMultipleCopy\fP\&. .SS "void SoNode::doAction (\fBSoAction\fP *action)\fC [virtual]\fP" This function performs the typical operation of a node for any action\&. .PP Reimplemented in \fBSoSceneTexture2\fP, \fBSoCamera\fP, \fBSoWWWInline\fP, \fBSoVRMLInline\fP, \fBSoBaseKit\fP, \fBSoTextureCombine\fP, \fBSoSceneTextureCubeMap\fP, \fBSoVRMLFontStyle\fP, \fBSoTextureCubeMap\fP, \fBSoShapeHints\fP, \fBSoTexture2\fP, \fBSoVRMLSwitch\fP, \fBSoTexture3\fP, \fBSoVRMLVertexShape\fP, \fBSoVertexProperty\fP, \fBSoNodeKitListPart\fP, \fBSoVRMLTransform\fP, \fBSoVRMLLOD\fP, \fBSoUnits\fP, \fBSoVRMLGroup\fP, \fBSoTransform\fP, \fBSoFontStyle\fP, \fBSoVRMLShape\fP, \fBSoMaterialBinding\fP, \fBSoNormalBinding\fP, \fBSoTransparencyType\fP, \fBSoVRMLParent\fP, \fBSoArray\fP, \fBSoBumpMap\fP, \fBSoDrawStyle\fP, \fBSoClipPlaneManip\fP, \fBSoDirectionalLightManip\fP, \fBSoVRMLImageTexture\fP, \fBSoVRMLProximitySensor\fP, \fBSoSpotLightManip\fP, \fBSoSeparator\fP, \fBSoPointLightManip\fP, \fBSoTransformManip\fP, \fBSoGroup\fP, \fBSoPolygonOffset\fP, \fBSoRotationXYZ\fP, \fBSoVertexAttribute\fP, \fBSoProfile\fP, \fBSoTextureCoordinateBinding\fP, \fBSoVRMLScript\fP, \fBSoAntiSquish\fP, \fBSoComplexity\fP, \fBSoMaterial\fP, \fBSoPickStyle\fP, \fBSoSwitch\fP, \fBSoTexture3Transform\fP, \fBSoVRMLMaterial\fP, \fBSoGeoCoordinate\fP, \fBSoVertexAttributeBinding\fP, \fBSoCacheHint\fP, \fBSoGeoLocation\fP, \fBSoLOD\fP, \fBSoResetTransform\fP, \fBSoTextureCoordinatePlane\fP, \fBSoTextureUnit\fP, \fBSoVRMLBillboard\fP, \fBSoVRMLTextureTransform\fP, \fBSoBumpMapTransform\fP, \fBSoLightModel\fP, \fBSoSurroundScale\fP, \fBSoTexture2Transform\fP, \fBSoVRMLAppearance\fP, \fBSoGeoOrigin\fP, \fBSoLevelOfDetail\fP, \fBSoFile\fP, \fBSoTextureCoordinateObject\fP, \fBSoMultipleCopy\fP, \fBSoNormal\fP, \fBSoPathSwitch\fP, \fBSoVRMLColor\fP, \fBSoVRMLCoordinate\fP, \fBSoVRMLNormal\fP, \fBSoVRMLPixelTexture\fP, \fBSoVRMLTextureCoordinate\fP, \fBSoVRMLVertexLine\fP, \fBSoVRMLVertexPoint\fP, \fBSoBaseColor\fP, \fBSoClipPlane\fP, \fBSoCoordinate3\fP, \fBSoCoordinate4\fP, \fBSoFont\fP, \fBSoPackedColor\fP, \fBSoTextureCoordinate3\fP, \fBSoTextureCoordinateReflectionMap\fP, \fBSoCallback\fP, \fBSoMatrixTransform\fP, \fBSoRotation\fP, \fBSoScale\fP, \fBSoTextureCoordinate2\fP, \fBSoTextureCoordinateNormalMap\fP, \fBSoTranslation\fP, \fBSoBumpMapCoordinate\fP, \fBSoProfileCoordinate2\fP, \fBSoProfileCoordinate3\fP, \fBSoTextureMatrixTransform\fP, \fBSoTransformSeparator\fP, \fBSoTextureCoordinateDefault\fP, \fBSoTextureCoordinateEnvironment\fP, \fBSoTextureCoordinateCube\fP, \fBSoTextureCoordinateCylinder\fP, and \fBSoTextureCoordinateSphere\fP\&. .SS "void SoNode::GLRender (\fBSoGLRenderAction\fP *action)\fC [virtual]\fP" Action method for the \fBSoGLRenderAction\fP\&. .PP This is called during rendering traversals\&.
