POWER ANIMATOR

PowerAnimator and Animator, also referred to simply as "Alias", the precursor to what is now Maya and StudioTools, was an expensive, complex, highly-integrated industrial 3D modeling, animation, and visual effects suite. It was the most widely used non-proprietary software in the visual effects and animation industries, and as such, it has had a long track record, starting with Terminator 2: Judgment Day in 1990 and ending in Star Wars Episode I: The Phantom Menace in 1999. PowerAnimator ran natively on MIPS based SGI Irix and IBM AIX systems up until the late 1990s.
The software itself featured one of the most complex user interfaces ever created, which allowed for an incredible amount of control over scene parameters, but made many tasks, such as animation, cumbersome and non-intuitive. It was expensive as well, apart from the enormous cost of SGI systems at the time. The standalone software retailed for $7,500, but was also sold with other modules, and a PowerPack containing all modules that retailed for $30,000 US.
