xWhat is DirectX?
Windows supports DirectX 8.0, which enhances the multimedia capabilities of your computer. DirectX provides access to the capabilities of your display and audio cards, which enables programs to provide realistic three-dimensional (3-D) graphics and immersive music and audio effects. DirectX is a set of low-level Application Programming Interfaces (APIs) that provides Windows programs with high-performance hardware-accelerated multimedia support.
DirectX enables the program to easily determine the hardware capabilities of your computer, and then sets the program parameters to match. This allows multimedia software programs to run on any Windows-based computer with DirectX compatible hardware and drivers and ensures that the multimedia programs take full advantage of high-performance hardware.
DirectX contains a set of APIs that provide access to the advanced features of high-performance hardware, such as 3-D graphics acceleration chips and sound cards. These APIs control low-level functions, including two-dimensional (2-D) graphics acceleration; support for input devices such as joysticks, keyboards, and mice; and control of sound mixing and sound output. The low-level functions are supported by these components that make up DirectX:
The Microsoft DirectDraw API supports extremely fast access to the accelerated hardware capabilities of a computer's video adapter It supports standard methods of displaying graphics on all video adapters, and faster, more direct access when using accelerated drivers. DirectDraw provides a device-independent way for programs, such as games and 2-D graphics packages, and Windows system components, such as digital video codecs, to gain access to the features of specific display devices without requiring any additional information from the user about the device's capabilities.
The Microsoft DirectSound API provides a link between programs and an audio...
