Could you go into more detail about what you are doing and then perhaps we can help?
Are you trying to use DirectDraw or Direct3D? If it is Direct3D that you are using then all vertices are kept in 3d coordinates but you can use an orthogonal projection to place objects in screen coordinates in 2d using direct3d.

| i mean the vertex location in 2d is like(150,250,25), but in 3d coordinate it is (1,-1,0) ,what's that mean |

| Well in 3D it is (1,-1,0) because yes it uses matrices. |
