There are two basic file types that the user's computer graphics cards can interpret:
X Files and OpenGL file types. And no, X Files are not strange paranormal experiences like those related in the psychicinvestigator.com. X Files are compatable with Microsoft's Direct X file format, a 3D standard.
The other standard in the industry is the populat OpenGL system for displaying 3D graphics.

We will consider importing 3D objects we have created in the earlier tutorials into two very different game creation software packages. The first is 3D Gamecreator and its more advanced Dark Basic programming kit and the Torque Game Engine. The first example uses Direct X (.x) files and the second utilizes their own file type, DTS (.dts). Both of these files can be exported from the MilkShape 3D program mentioned in the first tutorial.
