X file extension - Microsoft Direct-X SDK 3D graphics

What is x file? How to open x files?

File type specification:

3d graphics, CAD-CAM-CAE file type icon 3d graphics, CAD-CAM-CAE file type

The x file extension is associated with the Microsoft DirectX framework and used for files that contain ASCII formatted 3D positional chart with additional graphical data for 3D environments (objects) meshes.

The x file stores Mesh data (with vertex normals, vertex uv texture coordinates and vertex colors), materials, texture references, hierarchy and object animation.

Historically, in the early 1990s the leading 3D game engine was "Rendermorphics" from Ireland. Microsoft purchased the Rendermorphics company and renamed their technology to "DirectX v3" in 1995.

The 3 Irish developers subsequentely left Microsoft a few years later in 1997, after which time the DirectX X file format did not change, except for some additions of mesh skinning prior to 1999.
