|Microsoft DirectX 9.0|
The Conv3ds.exe utility converts three-dimensional (3-D) models produced by Autodesk 3-D Studio and other modeling packages to the Microsoft?DirectX?file format. By default, the utility produces binary .x files with no templates.
You can run Conv3ds.exe with no options, and it will produce an .x file containing a hierarchy of frames. For example, the following command produces an .x file called File.x from the .3ds file.
