You need to keep some kind of entity record, that stores position/orientation of the object, and then the mesh that represents the object graphically.

Then, to render your scene, you iterate over each entity, turn the position/orientation into transform matrices, and draw the respective meshes with these matrices.

In OpenGL, camera + object transform glom together into the MODELVIEW matris. In DirectX, these are separated into the WORLD and VIEW matrices.
