Direct3D. This helps make three-dimensional animation possible on your computer monitor. Direct3D is designed to provide a powerful link between your computer's video card and software programs that can render three-dimensional (3‑D) objects. The faster your computer can process animation, the more realistic the 3‑D objects, light, and motion on your monitor will appear to be.
DirectDraw. This helps produce two-dimensional (2‑D) visual effects. Your computer's video card and many software programs use DirectDraw to communicate with one another before sending the finished visual image to the monitor. Computer games, 2‑D graphics packages, and Windows system features all use DirectDraw.
DirectSound. This boosts the performance of audio effects on your computer and makes many subtle effects in audio mixing and playback possible. It provides a link between software programs and the hardware on your computer. DirectSound provides multimedia software programs, such as games and movies, with hardware acceleration, mixing capabilities, and access to the sound card.
