If you're asking how to do it in code, there are a few basic steps.
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(...)
That's about all you need to do if you already have the vertices in an appropriate D3D format. D3d8+ mesh functions do the rest.
Hello,
which directx Version do you use?
For Directx9 (Managed), i find a simple way to create a x-File is to use Ulead 3 Cool 3DStudio (30 day version available).
In the editor create an object, as you like and export it as a x-file.
Load in the meshviewer of directx9 SDK and optimize it with viewer.
to create:
mesh = Direct3D.Mesh.FromFile(x-f
material = New Direct3D.Material(.extende
For i = 0 To extendedMaterial.Length - 1
material(i) = .extendedMaterial(i).Mater
material(i).Ambient = .material(i).Diffuse
texture(i) = TextureLoader.FromFile(3DD
Next i
to render:
3DDevice.Transform.World = mesh.matrix
For i = 0 mesh.Material.Length - 1
3DDevice.Material = material(i)(i)
3DDevice.SetTexture(0, texture((i))
mesh.DrawSubset(i)
Next i
This code is simplified, it will create and render a static mesh.
for animation you must extract the verticies out of the mesh, modify them
an render the vertex buffer.
For a good tutorial in creating and rendering objects in directx9 see

You can use PolyTrans program to transform any 3D format (e.g., .MAX, .3DS, .FLT) to .X files. It is available in:

There are many simple ways:
-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 (altough for this u need to know how the file is build)
Hope this helped
