Scene composition What the scene contains and how it is arranged.
Scene graph
Nodes, transforms and referenced assets.
Node hierarchy
The objects in the scene and their spatial relations.
- Which nodes does the scene contain, and how are they parented and transformed?
- Which coordinate system, units and up-axis does the scene use?
Referenced assets
External meshes, textures and materials used.
- Which assets does the scene reference, in which versions?
- Under which licence may each referenced asset be used?
Interaction and behaviour What can happen in the scene.
Behaviours
Scripts, physics and interactive objects.
Interactive objects
Objects with behaviours, triggers or physics.
- Which objects respond to user or agent input, and how?
- Which scripts run in the scene, and from which sources?
Access and comfort
Accessibility and comfort settings for users.
- Which accessibility and motion comfort options does the scene offer?
- Are there content warnings, such as flashing lights, for users?
Versions and provenance How the scene was made and changed.
Authorship and versions
Authors, tools and version history.
Version history
Published versions and their changes.
- Which version of the scene is published, and what changed from the previous one?
- Who authored it, and with which tools or generators?

What it is Filled
A 3D scene or environment is a digital spatial composition of objects, geometry, materials, lights, cameras and behaviours arranged in a scene graph, which can be rendered, explored or interacted with. It is the assembled scene, not a single 3D asset, and differs from a whole virtual world with its users and economy and from a digital twin bound to a real counterpart.
Why it exists Filled
Spatial scene and interactive object graph
Distinguishing features Filled
- An assembled spatial composition, not a single mesh or texture asset.
- Distinct from a virtual world, which adds persistent users, accounts and economies.
- Unlike a digital twin, it need not correspond to any real object or place.
- The scene graph and its behaviours, not the rendered images, are the thing described.
What robots and AI may and may not do Filled
Must not
- Use assets in a scene against their licences.
- Present a scene as a faithful reproduction of a real place or object when it is not.
- Insert hidden scripts or tracking into a shared scene.
- Remove authorship or provenance metadata.
- Place content in a shared scene that harasses or endangers other users.
Only with a human decision
- Publishing a scene to a public or shared platform.
- Using a scene for training or safety-critical simulation decisions.
May
- Load, inspect and describe scene contents and structure.
- Navigate or act in a scene within the permissions given to the agent.
- Report missing assets, licence gaps and performance problems.
- Generate or edit scene drafts for human review.
Moral aspects Filled
- Immersive scenes can cause motion sickness or seizures, so comfort and warnings matter.
- Reproductions of real places, people or cultural sites raise questions of consent and respect.
- Creators of reused assets deserve attribution and fair licensing.
Who is affected
- Users exploring the scene
- Asset creators and scene authors
- People and places depicted
Owners Filled
Steward
The scene author or publisher that holds rights to the composition and maintains its versions.
Master systems
- Digital asset management system
- Scene or level repository
Links to other meta-models Filled
parent
- WM-VRT-002
What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Identified by the repository or platform identifier of the scene and its version.
- Referenced assets are identified by their own asset identifiers and checksums.
Direct properties not applicable Not applicable
Not applicable
A 3D scene is a digital composition; its units, scale and coordinate system are recorded as scene metadata, not as physical properties.
Recognition optional Filled
- Marked by a scene graph with nodes, transforms, materials, lights and cameras in a 3D scene format.
- Often confused with a single 3D asset, a rendered video or image, or a full virtual world.
Capabilities and actions required Filled
- Can be rendered, explored and interacted with in real time or offline.
- Can be composed from and decomposed into reusable assets.
Hazards and failure modes required Filled
- Flashing content or motion that triggers seizures or sickness.
- Malicious scripts embedded in shared scenes.
Standards and interfaces required Filled
- glTF 2.0 (ISO/IEC 12113) for transmission of scenes and assets.
- X3D (ISO/IEC 19775) for interactive 3D scenes.
- WebXR for presenting scenes in immersive browsers.
Context of use required Filled
- Used in games, film, architecture, training, simulation and extended reality.
- Increasingly generated or edited with AI tools.
Sources Filled
- ISO/IEC 12113 Runtime 3D asset delivery format (glTF 2.0), ISO and IEC
- ISO/IEC 19775 Extensible 3D (X3D), ISO and IEC
