Computer generated imagery (CGI) has evolved significantly since its beginnings in the 1950s. Early developments included the introduction of punch cards, videotape recording, and the coining of the term "computer graphics." CGI has many applications including medical imaging, video games, feature films, and architectural design. Key techniques in CGI include fractals for generating self-similar patterns, tweening for animating transitions between images, and rendering for final image output. The future of CGI is focused on achieving ever greater realism through virtual reality and motion capture.
