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/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).

Member Function Documentation

SoType SoVRMLInline::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

SoType SoVRMLInline::getTypeId (void) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

Implements SoBase.

const SoFieldData ** SoVRMLInline::getFieldDataPtr (void) [static], [protected]

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.

const SoFieldData * SoVRMLInline::getFieldData (void) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

void SoVRMLInline::initClass (void) [static]

void SoVRMLInline::setFullURLName (const SbString & urlref)

Sets the full (non-relative) URL name.

const SbString & SoVRMLInline::getFullURLName (void)

Returns the full URL name.

SoGroup * SoVRMLInline::copyChildren (void) const

Returns a copy of the children.

void SoVRMLInline::requestURLData (void)

Request URL data.

SbBool SoVRMLInline::isURLDataRequested (void) const

Returns TRUE if the URL data have been requested.

SbBool SoVRMLInline::isURLDataHere (void) const

Returns TRUE if the data have been loaded.

void SoVRMLInline::cancelURLDataRequest (void)

Cancel the URL data request.

void SoVRMLInline::setChildData (SoNode * urldata)

Sets the child data. Can be used by the URL fetch callback.

SoNode * SoVRMLInline::getChildData (void) const

Returns the child data (the scene loaded from the URL).

void SoVRMLInline::setFetchURLCallBack (SoVRMLInlineFetchURLCB * f, void * closure) [static]

Sets the callback used to handle URL loading.

void SoVRMLInline::setBoundingBoxVisibility (BboxVisibility b) [static]

Sets the bounding box visibility strategy.

SoVRMLInline::BboxVisibility SoVRMLInline::getBoundingBoxVisibility (void) [static]

Returns the bounding box visibility strategy.

void SoVRMLInline::setBoundingBoxColor (SbColor & color) [static]

Sets the color of the bounding box.

SbColor & SoVRMLInline::getBoundingBoxColor (void) [static]

Returns the color of the bounding box.

void SoVRMLInline::setReadAsSoFile (SbBool enable) [static]

Sets whether Inline nodes should be treated as a normal Inventor SoFile node.
