How was toy story made?

Toy Story was made using a combination of traditional animation techniques, computer-generated imagery (CGI), and 3D animation. The film was created by Pixar Animation Studios, which was a pioneer in the field of computer animation. The process of making Toy Story involved designing and modeling the characters, sets, and environments using computers, and then animating them using software. The animation was then combined with live-action elements, such as sound effects, music, and voice acting, to create the final product. The process was a collaborative effort between animators, artists, technicians, and filmmakers, who worked together to bring the story of Toy Story to life.
