The way objects are rendered on the screen depends on two things:
1. The global location of the objects. This is basic XYZ 3d space. You can use the POSITION OBJECT command to position objects at specifc points in 3d space.
2. The camera position and angle affect how objects in the game world are drawn to the screen. If you position an object at 0,0,0 and the camera at 3,0,-3 then the object would appear to be on the right. The camera moved back (Z axis) 3 units so it could see the object without bumping into it, and then left (X axis) 3 units and just like shaking hands with someone appears opposite even though you are both using your right hand the object appears to have moved toward the right.

Please don't take offense if you knew this already. And if that's the case then the short and sweet answer is go look up POSITION OBJECT.
