Fusion: Unity PBD physics on GPU

Fusion is built in the spirit of enabling developers to have “physics” in their game without sacrificing performance, or at least, not too much performance. We choose to base our simulation on Position-Based-Dynamics, which already gives good performances when running on CPU and pretty easy to parallelize.

PBD could support many types of physical objects, we choose to implement Cloth and Fluid since they are hard to achieve without actual physics simulation, and they give vivid results when finished.

We aimed at making a usable Unity plugin so that the users could easily add physics-conformed cloth and fluid in their game environment or make a game fully focused on interaction with fluid or cloth.
