Quick3D object MIME Type
MIME type details for model/x-q3o
In active use| MIME type | model/x-q3o |
|---|---|
| Extensions | .q3o |
| First standardized | Unknown; documented format version 3.0 |
| Created by | Quick3D |
| Browser support | Requires a compatible viewer |
| Example applications | Quick3D (legacy application) |
| Poly support | Partial. 3D features apply to supported Quick3D object content, not every file sharing the suffix. |
| Indexed by Poly | Yes. Filename search, plus visual similarity when supported geometry is processed. |
| Preview in Poly | Partial. Interactive preview when a supported model with visible geometry is available. |
| Poly agent | Partial. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files. An available visual rendition is required. |
What does model/x-q3o identify?
model/x-q3o is Poly's identifier for Quick3D object files using .q3o. It describes an object asset, rather than the related Quick3D scene format. This is a Poly-recognized identifier, not a claim of IANA registration.
A .q3o file is a Quick3D object file. Its binary structure includes mesh data, with optional materials and textures. The identifying signature is quick3Do.1
The related .q3s suffix describes a Quick3D scene. When recovering an old asset, retain both if they were supplied together. An object's shape and its presentation in a scene are different things.
Opening the file
Quick3D is the originating legacy application. If it is unavailable, use a viewer that explicitly lists Q3O support. General-purpose modelling tools do not necessarily include a Quick3D importer; verify support before relying on a conversion workflow.
Poly support
Poly previews supported Quick3D mesh geometry. Materials and lighting can look different from the legacy application, and the original file remains the source for any format-specific authoring details.
For a supported model, orbit, pan, and zoom let you inspect its shape. Search by filename, or by visual similarity when visual content is available. Available geometry and scene counts appear in 3D Details.
An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files. Ask about visible shape or compare models; use the original application for precise authoring work.
Background and alternatives
The documented Quick3D 3.0 layout distinguishes object files from scene files by their signatures and records.1 Do not confuse Quick3D with Apple's QuickDraw 3D; similar names do not establish format compatibility.
Export to OBJ for simple mesh exchange or glTF for a modern scene workflow. Compare orientation, scale, and appearance after conversion, and retain the original asset.
