OpenFX is an Open-Source 3D modeling, animation and rendering suite created by Dr. Stuart Ferguson. It has powerful feature-set that 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.
