What is a .X file?
The .X file extension is associated with Lex Source Code Files, but it is more commonly recognized as a 3D image file format utilized by DirectX technology. DirectX is a collection of APIs (Application Programming Interfaces) used primarily for developing and running applications with high-quality 3D graphics, most notably video games. The .X file format can include detailed information about 3D models such as their meshes (the framework that gives the model shape), textures (the images that are mapped onto the surface of the meshes to give them color and detail), animations (how the models move), and other objects that make up the 3D environment.
These files can be created or exported using the DirectX Software Development Kit (SDK) plugins designed for 3D modeling and animation software like 3ds Max and Maya. Additionally, there are custom exporters available for other 3D software programs such as Blender and DeleD, allowing a wide range of developers and artists to create content for DirectX applications.
To open or work with .X files, one of the primary tools was the Microsoft DirectX SDK. However, it's important to note that the Microsoft DirectX SDK has been discontinued. Despite this, there may still be other tools or updated versions of the DirectX development environment that can work with .X files. Also, since the description mentions that Lex source code files more often use the .L extension, it's crucial to differentiate between the two to ensure the correct software and approach are used when working with these files. For .X files specifically related to 3D graphics and DirectX, focusing on tools and software designed for 3D modeling and game development is advisable.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files. If you want to suggest edits or updates about .X file formats, example files, or programs that are compatible. Please contact us.
