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

Basic problem for visualization techniques is called depth cueing.

Some 3D objects are without depth information visible line and surface identification To highlight the visible lines display visible lines as dashed lines removing the invisible lines.
