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:
Shape { exposedField SFNode appearance NULL exposedField SFNode geometry NULL }
The Shape node has two fields, appearance and geometry, which are used to create rendered objects in the world. The appearance field contains an SoVRMLAppearance node that specifies the visual attributes (e.g., material and texture) to be applied to the geometry. The geometry field contains a geometry node. The specified geometry node is rendered with the specified appearance nodes applied. See 4.6.3, Shapes and geometry (<http://www.web3d.org/technicalinfo/specifications/vrml97/part1/concepts.html#4.6.3>), and SoVRMLAppearance, for more information.
4.14, Lighting model (<http://www.web3d.org/technicalinfo/specifications/vrml97/part1/concepts.html#4.14>), contains details of the VRML lighting model and the interaction between Appearance nodes and geometry nodes. If the geometry field is NULL, the object is not drawn.

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoNode. |
|
Returns
If it returns
The default method returns Reimplemented from SoNode. |
|
This function performs the typical operation of a node for any action. Reimplemented from SoNode. |
|
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. |
|
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. |
|
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. |
|
Action method for SoRayPickAction. Checks the ray specification of the action and tests for intersection with the data of the node. Nodes influencing relevant state variables for how picking is done also overrides this method. Reimplemented from SoNode. |
|
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.
Reimplemented from SoNode. |
|
Action method for SoWriteAction. Writes out a node object, and any connected nodes, engines etc, if necessary. Reimplemented from SoNode. |
|
Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables. Reimplemented from SoNode. |
|
Returns list of children for this node. Reimplemented from SoNode. |
|
Notifies all auditors for this instance when changes are made. Reimplemented from SoNode. |
|
Makes a deep copy of all data of from into this instance, except external scenegraph references if copyconnections is This is the method that should be overridden by subclasses which needs to account for internal data that are not handled automatically. 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..] } Reimplemented from SoNode. |
