ABSTRACT
This chapter is about real-time computer animation using the DirectDraw facility in DirectX. Before DirectX, animation in Windows was considered somewhat of an oxymoron. DirectX provides mechanisms that make possible graphics rendering at a high speed. One of these mechanisms is the storage of image data in so-called back buffers. The back buffers and the display surface can be rapidly flipped to simulate screen movement. The results are often a smooth and natural simulation of movement that can be used in computer games, simulations, and in high-performance applications.
