I was curious how the CG was created in Toy Story, since it was the first CG feature film ever made, and found this great description: https://community.spiceworks.com/topic/412181-this-week-in-history-toy-story-and-cgi
Compared to modern CG generation processes, Toy Story's CG was extremely primitive. The team first started by making models out of clay, after which they re-created them on a computer. Animators then hand-coded each motion control - Woody along had over 700 motion models, so this was no mean feat! Each computer-generated shot passed through eight separate teams, and every 8 seconds of footage took around a week to create as a result! After shading, light and visual effects were added, the shots were sent to a Sun Microsystem computer farm, that took between 45 minutes and 3 hours to render a single frame. As a result, the final film took 800,000 machine hours to render!!
