Dynamation was a 3D computer graphics particle generator program sold by Wavefront to run on SGI's IRIX operating system as part of The Advanced Visualizer.
It gave users an interactive environment to create and modify dynamic events such as water, clouds, rain, fire and dust.
The software was used to create visual effects in movies such as Twister, Last Action Hero, Balto, Crimson Tide, Heaven's Prisoners, Michael, Moses, Anaconda, Godzilla, Stuart Little, and Starship Troopers.
It was also utilized in the opening credits of Star Trek: Voyager to create an intricate interaction of the starship traveling through cosmic dust.
Dynamation's interactive particle engine has been integrated into the 3D computer graphics package Maya and is no longer sold as a separate product.
