Check our videoThe X file format, developed by Microsoft, is a 3D model file format used primarily for storing mesh data, animations, and textures in DirectX applications. It is supported by tools like DirectX SDK, Blender, and various 3D modeling software for creating and editing 3D assets. The format uses a hierarchical, text-based or binary structure with templates for defining geometry, materials, animations, and user-defined data, enabling extensibility and compatibility with DirectX rendering pipelines.
The GLTF is an open, royalty-free file format developed by the Khronos Group for efficient transmission and loading of 3D scenes and models. It is widely supported by 3D tools, engines, and platforms, including Blender, Unity, Unreal Engine, and web-based applications like Three.js. The format uses JSON for metadata, binary data for geometry and animations, and supports advanced features like PBR materials, morph targets, and skeletal animations, making it versatile for real-time rendering and interactive applications.
You can also convert X into many other file formats. Please see the complete list below.
