A Microsoft X file refers to a specific file format used by Microsoft DirectX, a collection of application programming interfaces (APIs) designed to handle multimedia-related tasks in Windows-based applications. The X file format is primarily used for 3D model storage and is commonly employed in computer graphics, gaming, and virtual reality applications. It serves as a standardized way to store and exchange 3D object data, including mesh geometry, materials, textures, animations, and hierarchy information, making it easier for developers to import and utilize 3D models within DirectX-powered applications.

Microsoft X files have a hierarchical structure, allowing complex 3D scenes to be represented efficiently. They typically use the extension ".x" and can be saved in either ASCII or binary format. While the ASCII format is human-readable and editable, the binary format offers faster loading times and reduced file sizes, making it more suitable for real-time applications. Developers can create or export X files from 3D modeling software or use specialized conversion tools to convert models from other formats into X files for use in DirectX-based projects.

Due to the popularity of DirectX in the gaming industry and other multimedia applications, the Microsoft X file format has played a significant role in facilitating the exchange and utilization of 3D assets. However, it's worth noting that as technology advances, new formats and standards may emerge, potentially impacting the prevalence of the X file format in future developments.

The STL, or Standard Triangle Language, file format has been around since the '80s and is supported by most modern 3D modelling applications. In particular, the STL format has become something of a standard format within the area of 3D printing, despite the rise of more modern formats such as 3MF.

STL files come in two flavours: binary or text format. The text format is human-readable, making it easy to perform manual edits, but can lead to very large file sizes. As you can imagine, the binary format is much more compact and represents the majority of the STL files you are likely to encounter.

The format itself is very simple; the 3D model is represented by a sequential list of triangles, with each triangle defined with 3 points consisting of their X, Y, and Z positions, along with an additional vector that contains the face normal (the direction the face is pointing). There is an additional attribute block for each triangle; however, this is largely unused and thus unsupported.

STL Converter Capabilities

When converting your X to STL our tool will attempt to accurately convert any color/material information.

Information for converting from X to STL

Your X file will be converted to a STL file using our unified 3D model and mesh conversion tool. Our X 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As both X and STL support color material information our tool will also attempt to convert the color information too.
