.x3d File Extension
.x3d files contain, which applications open them, and how Poly supports them. File extension details for .x3d
Partial Support| File type | Extensible 3D XML encoding |
|---|---|
| MIME type | |
| Encoding | UTF-8 XML text |
| Operating systems | Windows, macOS, Linux |
| Opens with | X3D-Edit, InstantReality, X3DOM |
| Poly support | Partial. Poly recognizes .x3d as 3D content and processes supported files. |
| Indexed by Poly | Yes. Poly indexes filenames and visual similarity for processed geometry; scene counts are displayed in Details. |
| Preview in Poly | Partial. Poly provides an interactive 3D preview for supported constructs. |
| Poly agent | Yes. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files. |
What kind of file is .x3d?
X3D is an ISO-ratified, royalty-free open standard for representing and communicating 3D scenes and objects. Its XML encoding maps the scene graph to XML elements and fields. Web3D specifies .x3d with model/x3d+xml.1 Profiles and versions determine which nodes are available.
How do I open a .x3d file?
X3D-Edit and InstantReality can open or import many Extensible 3D XML encoding files. Check export settings when a model contains materials, textures, lights, cameras, or animation. Conversion can discard format-specific data.
Poly support for .x3d
Poly recognizes .x3d as 3D content and indexes filenames and visual similarity for processed geometry. Scene counts are displayed in the Details panel. Poly's 3D preview and extracted counts depend on supported constructs.
| Construct | Poly behavior |
|---|---|
| Geometry and scene structure | Available when the file imports successfully. |
| Materials and textures | Depends on the constructs present and supported rendition. |
| Lighting, cameras, and animation | Available when present and supported. |
Working with .x3d
Keep the source before converting. glTF is a practical real-time delivery target. For CAD or BIM, retain the original exchange file and record its schema or application protocol.
