Autodesk Animator is a 2D computer animation and painting program published in 1989 for MS-DOS. It was considered groundbreaking when initially released. Functionality Animator gave the ability to do frame-by-frame animation (creating each frame as an individual picture, much like Traditional animation) . Animator Studio also had tweening features (transforming one shape into another by letting the computer draw each in-between shape onto a separate frame). Animator and Animator Pro supported FLI and FLC animation file formats, while Animator Studio also supported the AVI format. Animator was particular strong in Palette based editing, effects (like Color cycling) and animations a favored technology in the time of indexed CGA and VGA graphics modes. Unlike other DOS software from that time, Animator was not restricted by the 640 kilobyte conventional memory limitation as it utilized a DOS extender by Phar Lap. Animator's combination of twenty tools multiplied by twenty inks, 3D 'optics,' unparalleled palette handling, custom fonts and many other useful features (such as its own internal scripting language POCO), put it many years ahead of better known animation tools of the time. Development history Animator originates back to its author's Jim Kent earlier program Cyber Paint for the Atari ST. Jim Kent evolved in 1989 his software into Animator for Gary Yost's "Yost Group" for 80286 PCs with MS-DOS. Animator was then licensed to Autodesk, who published the software as Autodesk Animator. Releases Animator was debuted at SIGGRAPH 1989, featuring a VGA graphics mode of 320×200 pixels with 256 colors. In July 1991, the successor Animator Pro was released, with the significant improvement of allowing almost any resolution and color depth. The software was sold for approx. $800, significantly more expensive than the previous version, addressing the professional audience. The 1995 released Animator Studio was a complete re-write for Windows 95, but was not anymore developed by the Yost Group. Abandonment and legacy Eventually development of the product ended and support was discontinued by Autodesk. The trademark for "Autodesk Animator", filed on December 18, 1989, expired on July 21, 1997. Jim Kent kept copyrights to the 300,000 lines source code base of Animator Pro, and allowed it to be made available publicly under the open-source BSD license in 2009. The original 256 color Animator version for DOS is also provided as a freeware download. After some initial code review porting to modern platforms was started on GitHub. As of April 2014
