Changing Perspectives

You can change the whole world or you can change your own perspective. In a computer, changing a virtual world is just as easy as changing the camera view point.

With computer graphics, with the right set of values, you can move and rotate the virtual world in such a way that it looks as though you’re moving the virtual camera. When you get down to it, it’s just pushing matrices into the pipeline in OpenGL or DirectX or whatever 3D graphics engine you’re using.
