First computer key frame animation, first adult computer animation
1) The National Film Board of Canada, already a world center for animation art, also began experimentation with computer techniques in 1969. Most well-known ad the early pioneer inthis was artist Peter Foldes, who completed "Metadata" in 1971. This film comprised drawings animated by gradually changing from one image to the next, a technique known as "interpolating" (also known as "inbetweening" or "morphing"), which also featured in a number of earlier art examples during the 1960s.
2) This is an experimental 2D animated short drawn on a data tablet by Peter Foldes, who used the world's first key frame animation software, invented by Nestor Burtnyk and Marceli Wein.
3) A key frame in animation and filmmaking is a drawing that defines the starting and ending points of any smooth transition. The drawings are called "frames" because their position in time is measured in frames on a strip of film. A sequence of key frames defines which movement the viewer will see, whereas the position of the key frames on the film, video, or animation defines the timing of the movement. Because only two or three key frames over the span of a second do not create the illusion of movement, the remaining frames are filled with inbetweens.
4) First adult video game with graphics was Yakyuken (1981)
4) First videogame that used key frame animation is Outcast (1999).
