Hvad er REALITY-filformatet?
En .reality-fil er en augmented reality-scene bygget til Apples RealityKit-framework. Apple introducerede formatet med Reality Composer i 2019 for at pakke AR-indhold, der kan afspilles på tværs af iPhone, iPad, Mac og Vision Pro. Under motorhjelmen er det et ZIP-baseret arkiv, der samler 3D-modeller, teksturer, materialer, rumlig lyd, fysik, animationer, ankre og interaktive handlinger i én fil.
3D-nyttelasten kommer fra Apples USD-pipeline, så en .reality-scene bærer den samme geometri, som en tilsvarende .usdz-fil ville, plus RealityKit-interaktivitet såsom triggere og handlinger. De fleste møder en af disse filer, når de trykker på et AR-objekt på en webside eller i Beskeder, hvilket sender den videre til AR Quick Look.
Sikkerhed og tryghed
RISIKO: MEDIUMA .reality file can contain scripts of interactive behaviors and is opened by system components like AR Quick Look, so treat files from unknown sources with the same caution as any downloaded 3D content. The file itself is data rather than an executable, and Apple sandboxes AR Quick Look. There is no widespread malware associated with the format, but a malformed archive could in theory try to exploit a parser bug, so keep iOS, iPadOS, and macOS updated.
Formatdetaljer
kort fortalt- Reality (Pret-a-3D plugin for LuxRender) - Reality is a rendering plugin for Daz Studio and Poser by Pret-a-3D that exports scenes to LuxRender; it was released as open source under the BSD 3-Clause License in 2019. It is a separate product from Apple's format and does not use a .reality scene extension in the same way.
- Generic 'reality' project or config files - Some unrelated apps and games use a .reality suffix for internal scene or configuration data. These are niche and not associated with a single dominant tool.
Programmer der åbner REALITY-filer
.reality file (or its .rcproject source) inside Xcode's Reality Composer editor to inspect and edit the scene; note Reality Composer for Mac shipped through Xcode 14.3.1. .reality output for visionOS, iOS, and macOS projects on your Mac. .reality file in Finder and press Space to preview the scene with Quick Look. .reality file in Files, Safari, or Messages to preview the AR scene full-screen and place it in your surroundings. .reality scenes on iPhone or iPad, adjusting objects, behaviors, and anchors before exporting. .reality file to launch AR Quick Look and view the scene in augmented reality. .reality scenes on iPad, then export or share them for AR Quick Look. .reality content in a visionOS app through RealityView for spatial playback on Apple Vision Pro. Tekniske detaljer
dyb specifikation| Encoding | Binary archive (ZIP-based) |
| Byte order | Little-endian (ZIP container fields) |
| Container | ZIP archive holding USD/USDZ scene data plus RealityKit behaviors and metadata |
| Compression | DEFLATE / stored, per ZIP entry |
| Encryption | None by default |
| Typical size | Hundreds of KB to tens of MB depending on meshes, textures, and audio |
| Structure | Compressed archive that bundles 3D models (USD/USDZ), textures, materials, spatial audio, physics properties, animations, anchors, and interactive behaviors authored in Reality Composer or Reality Composer Pro. Content is loaded at runtime by RealityKit or previewed through AR Quick Look. |
| Integrity | CRC-32 per entry (inherited from the ZIP container) |
| Platforms | iOS, iPadOS, macOS, visionOS, tvOS |
| Notes | The .reality format is closely tied to Apple's USD/USDZ pipeline; a scene saved as .reality carries the same 3D payload as a comparable .usdz file but adds RealityKit interactivity such as triggers, actions, and behaviors. It is Apple-proprietary and is not natively readable on Windows or Android. Reality Composer for macOS shipped with Xcode 11 through 14.3.1; authoring later moved to Reality Composer Pro. |

Ofte stillede spørgsmål
Hvordan åbner jeg en .reality-fil på min iPhone?
Kan jeg åbne en .reality-fil på Windows eller Android?
.usdz eller .glb, som har bredere understøttelse.Hvad er forskellen på en .reality-fil og en .usdz-fil?
.usdz-fil er beregnet til portabel AR-visning, mens en .reality-fil tilføjer RealityKit-interaktivitet såsom triggere, handlinger og adfærd oprettet i Reality Composer.Hvilken app opretter .reality-filer?
.reality-filer. Xcode kan også bygge en automatisk fra et .rcproject under en projektbygning.Hvorfor vil min .reality-fil ikke åbne i et 3D-modelleringsprogram?
.usdz først, og importer derefter denne i Blender eller en anden USD-kompatibel applikation for at arbejde med geometrien.
