How To Create DirectX (.X) file

Using Tools

• Get yourself a program named TrueSpace or Milkshape, which can export Models into this format (and create them)
• Get a Plug in for any other 3D modeler (Maya Plugin and others are included with the DirectX9 SDK)
• Create 3DS Files using almost Any Modeler (3DS is more or less a standard format) and use the Program supplied with the SDK to convert it into .X format
• Open the File in WordPad and u can create/modify them, since they are not stored in any compressed/unreadable format (although for this u need to know how the file is build)
  

Programmatically

1. Create the mesh
   

   D3DXCreateMeshFVF(...)

2. Lock the vertex buffer and copy your vertices into it
   

   outMesh->LockVertexBuffer(...)

3. Lock the index bufer and copy indices into it
   

   outMesh->LockIndexBuffer(...)

4. Save it to a file
   

   D3DXSaveMeshToX(...)
