This node provides a way to split your models into a set of "component" models to include into larger "master" files.
Just provide the name of the model file to include in the SoFile::name field, and it will automatically be loaded and have its nodes inserted into the scenegraph at the point of the SoFile node.
You can also set the SoFile::name field manually. Such an action will then automatically trigger an invocation of a read operation which imports the filename you set in the field.

Constructor. |
|
Destructor. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. 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 SoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented from SoNode. |
|
Action method for SoHandleEventAction. Inspects the event data from action, and processes it if it is something which this node should react to. Nodes influencing relevant state variables for how event handling is done also overrides this method. Reimplemented from SoNode. |
|
Action method for SoPickAction. Does common processing for SoPickAction action instances. 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 a subgraph with a deep copy of the children of this node. |
|
Returns list of children for this node. 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. |
|
Returns the read filename, possibly including the (relative) path where the file was found. Returns an empty string if no file has been read. This method is an extension versus the Open Inventor API. |
|
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.
flags is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from SoNode. |
|
Filename for model file to insert in the scenegraph at the location of the SoFile node. |
