KRAKATOA is Frantic Films production-proven Volumetric Particle
Rendering Manipulation and Management Toolkit.

It provides a pipeline for acquiring caching deforming shading and
rendering vast quantities of particles at unprecedented speed to represent
natural phenomena like dust smoke silt ocean surface foam plasma and
even solid objects. Krakatoa integrates well with Particle Flow the
flexible 3ds Max built-in Event-Driven Particle System and provides data
exchange capabilities for sharing particles with other 3D and simulation
applications.
