Wavefront Technologies was a computer graphics company that developed and sold animation software used in Hollywood motion pictures and other industries. It was founded in 1984, in Santa Barbara, California, by Bill Kovacs, Larry Barels, Mark Sylvester. They started the company to produce computer graphics for movies and television commercials, and to market their own software, as there were no off-the-shelf computer animation tools available at the time. In 1995, Wavefront Technologies was purchased by Silicon Graphics and merged with Alias Research to form Alias|Wavefront. Now is owned by Autodesk.
