I would like to develop a 3D game with 2D background just like FF8. The map and the camera have scrolling function to look at the player. How can I do that? Please give me some tips to do that!!! Thanks...

You''re asking for quite a tall order but maybe I can give you an example that will help you get started. Imagine a chess board. The board itself and the tiles are all 2D. The peices are 3D. Now look directly down at the board. The background the board is still 2D. The game peices, the players or the 3D objects in the game are 3D but they are being looked directly down upon. Now take this into the land of the computer. If you were trying to render the scene I just described you would first paint the background(the 2D shess board) onto the offscreen buffer. Then you would rendeer the chess peices from the top down perspective and then raster them in the appropriate places on the screen. If you have a picture that was taken with adiferent perspective (ie on the side or looking down at an angle) would need to know the perspectve parameters so that you could perform the right transformations on the objects.

Ooo...
Thanks...
