Can you tell which main components (hardware and software) are needed for computer graphics?
Besides the computer, some special devices and software may be needed especially for computer graphics. For hardware, a special high-resolution, color monitor is often used and some input tools, like mouse and joy-sticker, and hard-copy devices, e.g. high-resolution color printer, might be needed. For software, some special purpose utilities (device-dependent and device-independent) are required for handling processing in computer graphics.
