In Ghost of Tsushima, the Guiding Wind is a central gameplay mechanic. To support the illusion that there is actual wind blowing, many separate systems work in concert to simulate wind-driven motion, so that everything in the world reacts appropriately as the wind changes direction. These simulations are not always perfectly accurate, but they are quite fast, handling thousands of pieces of cloth, hundreds of thousands of particles, and millions of blades of grass. I will present a variety of tips and tricks we use to make these simulations fast and believable, while utilizing the Playstation GPU to its maximum.
This talk is less a tutorial in how to make perfectly-real simulations, and more a collection of specific tricks and techniques we used to make our sims run very fast on the PS4 GPU.
Programmers and technical artists with an interest in procedural GPU-based simulation
