Computer Art

Computer graphics methods are widely used in both fine arts and commercial art applications. Artists use a variety of computer methods, including special purpose hardware, artist's paintbrush programs (such as Lumena), other paint packages (such as PixelPaint and SuperPaint), specially developed softwares, symbolic mathematics packages (such as Mathematica), CAD packages, desktop publishing software, and animation packages that provide facilities for designing object shapes and specifying object motions.
Fine artists use a variety of other computer technologies to produce images. For many applications of commercial art (and in motion pictures and other applications), photorealistic techniques are used to render images of a product. Animations are also used frequently in advertising, and television commercials are produced frame by frame, where each frame of the motion is rendered and saved as an image file. In each successive frame, the motion is simulated by moving object positions slightly from their positions in the previous frame. When all frames in the animation sequence have been rendered, the frames are transferred to film or stored in a video buffer for playback. Film animations require 24 frames for each second in the animation second sequence. If the animation is to be played back on a video monitor, 30 frames per second are required.
A common graphics method employed in many commercials is morphing, where one object is transformed into another. This method has been used in TV commercials to turn an oil can into an automobile engine, an automobile into a tiger, a puddle of water into a tire, and one person's face into another face.
