Houdini is a 3D animation software application developed by Toronto-based SideFX, who adapted it from the PRISMS suite of procedural generation software tools. Houdini's exclusive attention to procedural generation distinguishes it from other 3D computer graphics software. Houdini is most commonly used for the creation of visual effects in film and games. It is used by major VFX companies such as Walt Disney Animation Studios, Pixar, DreamWorks Animation, Double Negative, ILM, MPC, Framestore, Sony Pictures Imageworks, Method Studios and The Mill.
