The SoVRMLInline class is used to insert VRML files into a scene.
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:
Inline { exposedField MFString url [] field SFVec3f bboxCenter 0 0 0 # (-,) field SFVec3f bboxSize -1 -1 -1 # (0,) or -1,-1,-1 }
The Inline node is a grouping node that reads its children data from a location in the World Wide Web. Exactly when its children are read and displayed is not defined (e.g. reading the children may be delayed until the Inline node's bounding box is visible to the viewer). The url field specifies the URL containing the children. An Inline node with an empty URL does nothing.
Each specified URL shall refer to a valid VRML file that contains a list of children nodes, prototypes, and routes at the top level as described in 4.6.5, Grouping and children nodes.
The results are undefined if the URL refers to a file that is not VRML or if the VRML file contains non-children nodes at the top level.
If multiple URLs are specified, the browser may display a URL of a lower preference VRML file while it is obtaining, or if it is unable to obtain, the higher preference VRML file. Details on the url field and preference order can be found in 4.5, VRML and the World Wide Web (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.5).
The results are undefined if the contents of the URL change after it has been loaded.
The bboxCenter and bboxSize fields specify a bounding box that encloses the Inline node's children. This is a hint that may be used for optimization purposes. The results are undefined if the specified bounding box is smaller than the actual bounding box of the children at any time. A default bboxSize value, (-1, -1, -1), implies that the bounding box is not specified and if needed shall be calculated by the browser. A description of the bboxCenter and bboxSize fields is in 4.6.4, Bounding boxes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.4).

SoVRMLInline::SoVRMLInline | ( | void | ) |
Constructor
|
protectedvirtual |
Destructor.
|
virtual |
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.
This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
|
virtual |
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 calculate their bounding box also override this method to change the relevant state variables.
Reimplemented from SoNode.
|
static |
Returns the bounding box visibility strategy.
Returns the child data (the scene loaded from the URL).
|
virtual |
Returns list of children for this node.
Reimplemented from SoNode.
This static method returns the SoType object associated with objects of this class.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoFieldContainer.
|
staticprotected |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Returns the SoFieldData class which holds information about fields in this node.
|
virtual |
Action method for SoGetMatrixAction.
Updates action by accumulating with the transformation matrix of this node (if any).
Reimplemented from SoNode.
|
virtual |
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 calculate their primitive count also override this method to change the relevant state variables.
Reimplemented from SoNode.
|
static |
Returns whether Inline nodes are read as SoFile nodes.
|
virtual |
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method.
Reimplemented from SoNode.
|
virtual |
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 override this method.
Reimplemented from SoNode.
SbBool SoVRMLInline::isURLDataHere | ( | void | ) | const |
Returns TRUE if the data have been loaded.
SbBool SoVRMLInline::isURLDataRequested | ( | void | ) | const |
Returns TRUE if the URL data have been requested.
|
virtual |
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
|
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.
Reimplemented from SoNode.
Sets the color of the bounding box.
|
static |
Sets the bounding box visibility strategy.
Sets the child data. Can be used by the URL fetch callback.
Sets the callback used to handle URL loading.
|
static |
Sets whether Inline nodes should be treated as a normal Inventor SoFile node.
