Particle System with High-Level Elements

We present a particle system with simple mass spring elements and propose a complete GPU implementation of the system in shader programs. In this system, there is a large number of small meshes we refer to as molecules. Each particle is moved independently according to external forces that model fluid, then restoration forces are applied onto every particle along the springs incident on it. The end result is a large set of objects noticeably aligned with their local flow and interacting with the environment.
