OpenFX is an Open-Source 3D modeling, animation and rendering suite created by Dr. Stuart Ferguson. He made the decision to release the source code to the public in the middle of 1999, and the product formerly named SoftF/X was renamed to OpenFX. It has now been released under the terms of the GNU General Public Licence.
A powerful feature-set includes a full renderer and raytrace engine, NURBS support, kinematics-based animation, morphing, and an extensive plugin API.
Plugin capabilities include image post processor effects such as lens flare, fog and depth of field. Animation effects such as explosions, waves and dissolves add enormously to the flexibility of the program. Check out the full list of the various effect types and let your imagination run wild!
Currently, OpenFX only runs on the Win32 platform, which includes Windows 95/98/NT/2000. There are plans afoot to port it to Linux/*BSD platforms, and it currently runs fairly well under these by using the WINE set of libraries.
