Detailed Description

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/x3d/specifications/vrml/ISO-IEC-14772-VRML97/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/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.4).

Member Function Documentation

◆ getTypeId()

SoType SoVRMLInline::getTypeId ( void  ) const
virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

◆ getFieldData()
