  class World
  {
  private Device _device;
  private _transform1, _transform2;
  
  public World( Device device )
  {
  _device = device;
  
  _transform1 = Matrix.Translation( x1, y1, z1 );
  _transform2 = Matrix.Translation( x2, y2, z2 );
  }
  
  public void Daw()
  {
  _device.Transform.World = _trasform1;
  (draw mesh1)
  
  _device.Transform.World = _trasform2;
  (draw mesh2)
  }
  }
  
  just set the Device.Transform.World property to the matrix of each mesh before you draw it

  To display in DX you need to set 3 matrix PROJECTION, VIEW and WORLD

  You set the projection each time the window change proportion
  but only once by frame
  
  You set the View each time you change you point of view of where you look at
  Only once by frame
  
  You use LookAt Function to set it easily
  
  For the World matrix you define one each time you need to displace something
  in the world
  
  So you set the fist 2 matrix
  And then set one world matrix for each of your object in the scene
  
  Set World Matrix
  Draw Mesh 1

  Set World Matrix at different position and rotation
  Draw Mesh 2

  Think about the VIEW matrix as ONE oriented camera in the scene
  
  And think of the WORLD matrix as the placement matrix for any object in the scene

  So you set many time the WORLD matrix to move stuff around

  Also, how would I change the positions of two different meshes

  Okay, so something like this

  mydevice.Transform.World = Matrix.Translation(myx,myy,myz);

  Then I could just get keyinput to either add to myx, myy, or myz

  Thanks!
