The popular Dancing Baby animation which went viral in the 1990s employed no motion capture. Everything was created and rendered on the computer.
The video was created using Autodesk 3ds Max (formerly 3D Studio Max). It was made by the team that had developed Character Studio, a tool for the 3D computer graphics program.
The popularity of the Dancing Baby soared after John Woodell, a web developer, created an animated gif from the original movie and put it up on his employers web site. From there, the highly compressed animated gif file spread quickly around the world and started appearing on other web sites, commercials, music videos and even TV programs.
