Pixar Animation Studios, or simply Pixar (/ˈpɪksɑr/), is an American computer animation film studio based in Emeryville, California. The studio is best known for its CGI-animated feature films created with PhotoRealistic RenderMan, its own implementation of the industry-standard RenderMan image-rendering application programming interface used to generate high-quality images. Pixar began in 1979 as the Graphics Group, part of the computer division of Lucasfilm before its spin-out as a corporation in 1986 with funding by Apple Inc. cofounder Steve Jobs, who became its majority shareholder.
