Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

containerField [containerField type NMTOKEN "texture"]
containerField is a field-label prefix indicating this node's field relationship to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children' for Group node, containerField='proxy' for hidden proxy shape within a Collision node, etc.
Hint: containerField attribute is part of XML encoding for X3D scenes, and corresponds to the always-declared field labels in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different than the corresponding DEF declaration of that node.

containerField [containerField type NMTOKEN "attrib"]
containerField is a field-label prefix indicating this node's field relationship to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children' for Group node, containerField='proxy' for hidden proxy shape within a Collision node, etc.
Hint: containerField attribute is part of XML encoding for X3D scenes, and corresponds to the always-declared field labels in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different than the corresponding DEF declaration of that node.

USE [USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

url [url accessType inputOutput, type MFString CDATA #IMPLIED]
Address of replacement world, activated by the user selecting Shape geometry within the Anchor children nodes.
Hint: jump to a world's internal viewpoint by appending viewpoint name (e.g. #ViewpointName, someOtherCoolWorld.x3d#GrandTour).
Hint: jump to a local viewpoint by only using viewpoint name (e.g. #GrandTour).
Hint: binding a different Viewpoint triggers an isBound event that can initiate other user-arrival reactions via event chains to interpolators or scripts.
Hint: MFString arrays can have multiple values, so separate each individual string by quote marks "https://www.web3d.org" "https://www.web3d.org/about" "etc."
Hint: alternative XML encoding for quotation mark " is " (which is an example of a character entity).
Warning: strictly match directory and filename capitalization for http links! This is important for portability. Some operating systems are forgiving of capitalization mismatches, but http/https url addresses and paths in Unix-based operating systems are all case sensitive and intolerant of uppercase/lowercase mismatches.
Hint: can replace embedded blank(s) in url queries with %20 for each blank character.
Hint: pop up a new window with url value as follows: "JavaScript:window.open('somePage.html','popup','width=240,height=240');location.href='HelloWorld.x3d'"

containerField [containerField type NMTOKEN "texture"]
containerField is a field-label prefix indicating this node's field relationship to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children' for Group node, containerField='proxy' for hidden proxy shape within a Collision node, etc.
Hint: containerField attribute is part of XML encoding for X3D scenes, and corresponds to the always-declared field labels in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different than the corresponding DEF declaration of that node.

ImageTexture3D (X3D version 3.1 or later) ImageTexture3D defines a 3D image-based texture map by specifying a single image file that contains complete 3D data.
Warning: there are no required file formats, but at least one of the following formats is recommended for volume support in an X3D browser.
Hint: Microsoft DirectDraw Surface (DDS) https://docs.microsoft.com/en-us/windows/win32/direct3ddds/dx-graphics-dds
Hint: Digital Imaging and Communications in Medicine (DICOM) https://www.dicomstandard.org Nevertheless DDS, DICOM, NRRD and/or .vol formats are recommended.

DEF [DEF type ID #IMPLIED]
DEF defines a unique ID name for this node, referenceable by other nodes.
Hint: descriptive DEF names improve clarity and help document a model.
Hint: well-defined names can simplify design and debugging through improved author understanding.
Hint: X3D Scene Authoring Hints, Naming Conventions https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions

USE [USE type IDREF #IMPLIED]
USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
Hint: USE references to previously defined DEF geometry (instead of duplicating nodes) can improve performance.
Warning: do NOT include any child nodes, a DEF attribute, or any other attribute values (except for containerField) when defining a USE attribute.
Warning: each USE value must match a corresponding DEF value that is defined earlier in the scene.

url [url accessType inputOutput, type MFString CDATA #IMPLIED]
Location and filename of image. Multiple locations are more reliable, and including a Web address lets e-mail attachments work.
Hint: MFString arrays can have multiple values, so separate each individual string by quote marks "https://www.web3d.org" "https://www.web3d.org/about" "etc."
Hint: alternative XML encoding for quotation mark " is " (which is an example of a character entity).
Warning: strictly match directory and filename capitalization for http links! This is important for portability. Some operating systems are forgiving of capitalization mismatches, but http/https url addresses and paths in Unix-based operating systems are all case sensitive and intolerant of uppercase/lowercase mismatches.
Hint: can replace embedded blank(s) in url queries with %20 for each blank character.
Hint: X3D Scene Authoring Hints, urls https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#urls

Whether to vertically repeat texture along R axis.

containerField [containerField type NMTOKEN (texture | watchList | back | bottom | front | left | right | top | backTexture | bottomTexture | frontTexture | leftTexture | rightTexture | topTexture) "texture"]
containerField is a field-label prefix indicating this node's field relationship to its parent node, for example <Transform><Shape containerField='children'/></Transform>.
Hint: default containerField values for each node are correct in most cases, so the need to override default containerField values is rare.
Hint: example values include containerField='geometry' for Box node, containerField='children' for Group node, containerField='proxy' for hidden proxy shape within a Collision node, etc.
Hint: containerField attribute is part of XML encoding for X3D scenes, and corresponds to the always-declared field labels in the ClassicVRML and VRML97 file encodings.
Hint: USE node instances are allowed to have a containerField value that is different than the corresponding DEF declaration of that node.
