What I want to ask you is 3D RTS Camera Modes. You know Real Time Strategy games has different view of camera. Which generally looking to the map from some certain heigth with 45 angle. Actually I cannot achive this RTS camera mode. For now, what I have is, terrain from beginner's guide 3d lessons video tutorials( which is from this link http://creators.xna.com/en-US/education/gettingstarted/bg3d/chapter4). I draw the terrain model, and want to position terrain or camera so that I can wander around with RTS mode, currently i can implement quake like fps cam and moving freely. Also there is a game called "XNA RTS - Ambassador" where I really want to achive and have their camera mode with all functions, however i'm very at the beginning. Can any one help and show and share some RTS camera mode code ? Or have some tutorials or ideas ?
