Computers and Movies 2D Animation Computer-generated Imagery (CGI) Computer Animation 3D vision/glasses

Computer Graphics Bitmap and Vector Graphics Pixel and Sprite graphics Commonly used in Video games unrealistic

2D Animation Before CGI, done by painstakingly drawing each frame. Bitmap and vector graphics automated computerized animation flash, powerpoint, GIF

CGI first used in 1968 by Russian mathematicians and physicists led by N.Konstantinov mathematical model

CGI too rudimentary Early application: Simple e.g. Star Wars (1977) more analog than digital

Computer Rendering Render objects using computer graphics made possible by 32 bit processor graphics dedicated processors Tron(1982)- Lightcycle

CGI CGI effect become more realistic 3D rendered objects realistic animations. Terminator(1984)

Computer Animation high polygon graphics paired with motion capture allowed for realism Toy Story(1995) first fully CGI animated movie

3D Vision Red-Cyan Anagylph Initial Attempts were unimpressive Ruined the color of the film

3D Vision better eyewear-Polarized glasses better 3D effect does not restrict film colors more expensive projector motion sickness

Problems: Too Realistic Avatar (2009) reports of viewers being depressed longing for a computer generated world

Problems: Too Realistic Avatar (2009) reports of viewers being depressed longing for a computer generated world help people understand it is only a fictional world

Problems: Uncanny Valley Revulsion of human-like technology but not exactly Robotics AI 3D computer animation

Problems: Uncanny Valley Revulsion of human-like technology but not exactly Good design can lift human-looking entities out of the valley

Problems: Hoax + CGI false footage of CGI UFO “Golden Eagle Snatches a child” video

Problems: Hoax + CGI false footage of CGI UFO “Golden Eagle Snatches a child” video be critical of what you see

Future Problems Technological advancements will leads to: CGI will always seem better than the real world Technology & CGI will be indistinguishable from real life.
