Folks, I am looking to create a 3D RTS game. The question I have is what type of mapping system do I use. Do I use a 3D tile based system? If so, how do I implement this? WHat does a 3D tile system entail? Do I just render the scene and keep a height map? I understand the theorey behind a 2d tile mapping system, but I want to create a 3d game with mountains and hills and with the ability to rotate the camera and what not. What kind of mapping system do I use? Any ideas / suggestions are very much appreciated. Thanks, Mike Hocking
