What kind of file is .xgl?

XGL is XML for visualizing 3D information with an OpenGL-oriented scene model. Its specification describes worlds, objects, triangle meshes, materials, lights, textures, transforms, and ID-based references.1 ZGL is the compressed spelling for this family.

How do I open a .xgl file?

XGL viewers is the most reliable first choice. Other tools may import a subset of the geometry or scene constructs. Conversion to glTF or OBJ can improve interchange, but may discard materials, animation, application state, or scene relationships.

Poly support for .xgl

Poly recognizes .xgl as 3D content and indexes filenames and visual similarity for processed geometry. Scene counts are displayed in the Details panel. It can provide an interactive preview when the file imports successfully. An optimized rendition of the 3D object or scene is provided to the agent, allowing compact yet information-rich multimodal interaction with 3D files.

Keep the original before converting. For archives and scenes, keep referenced resources together so other applications can resolve them.
