Using Point cloud data in DirectX

I need to incorporate point cloud data denerated by a 3D LASER scanner into my DirectX app. Can anyone help me with this problem?

I'm also looking for a program to convert .slt (StereoLithography) files to .X (DirectX mesh) files.

Details of the problem--

I have point cloud data files of some 3D archeological models. These files were generated by a 3D scanner. Data is contained in a textfile which contains x,y and z coordinates of points saparated by space. Each point is listed on a saparate line

eg.
x y z

1.0000 1.2444 1.4556
2.0000 2.3333 4.7789

Now i want to display this data usinng DirectX without converting it to mesh.
