Overview
ImageTextureAtlas defines a 3D image-based texture map by specifying a single image file that contains slices for complete 3D data.
The ImageTextureAtlas node belongs to the Texturing3D component and its default container field is texture. It is available since X3D version 4.0 or later.

Fields
SFNode [in, out] metadata NULL [X3DMetadataObject]
Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.
SFString [in, out] description “”
Author-provided prose that describes intended purpose of the url asset.
Hint
- Many XML tools substitute XML character references for special characters automatically if needed within an attribute value (such as & for & ampersand character, or " for “ quotation-mark character).
SFBool [in, out] load TRUE
load=true means load immediately, load=false means defer loading or else unload a previously loaded asset.
Hints
- Allows author to design when ImageTextureAtlas loading occurs via user interaction, event chains or scripting.
- Use a separate LoadSensor node to detect when loading is complete.
MFString [in, out] url [ ] [URI]
Location and filename of image. Multiple locations are more reliable, and including a Web address lets e-mail attachments work.
Hints
- MFString arrays can have multiple values, so separate each individual string by quote marks “https://www.web3d.org” “https://www.web3d.org/about” “etc.” XML encoding for quotation mark “ is " (which is called a character entity). Can replace embedded blank(s) in url queries with %20 for each blank character.
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 and other operating systems are not.

SFTime [in, out] autoRefresh 0 [0,∞)
autoRefresh defines interval in seconds before automatic reload of current url asset is performed.
Hints
- If preceding file loading fails or load field is false, no refresh is performed.
- Repeated refresh attempts to reload currently loaded entry of url list. If that fails, the browser retries other entries in the url list.
Warning
- Automatically reloading content has security considerations and needs to be considered carefully.
SFTime [in, out] autoRefreshTimeLimit 3600 [0,∞)
autoRefreshTimeLimit defines maximum duration that automatic refresh activity can occur.
Hint
- Automatic refresh is different than query and response timeouts performed by a networking library while sequentially attempting to retrieve addressed content from a url list.
Warning
- Automatically reloading content has security considerations and needs to be considered carefully.
SFInt32 [in, out] slicesOverX 0 [0,∞)
Number of images in x direction.
SFInt32 [in, out] slicesOverY 0 [0,∞)
Number of images in y direction.
SFInt32 [in, out] numberOfSlices 0 [0,∞)
Total number of images.
SFBool [ ] repeatS FALSE
Whether to horizontally repeat texture along S axis.
SFBool [ ] repeatT FALSE
Whether to vertically repeat texture along T axis.
SFBool [ ] repeatR FALSE
Whether to vertically repeat texture along R axis.
SFNode [ ] textureProperties NULL [TextureProperties]
Field textureProperties.
