Ignis: Eulerian Fluid Simulation and Rendering at VR Frame Rates
Charlie Shenton · 2023
We present Ignis, a GPU Eulerian fluid solver capable of simulating and rendering at VR resolutions and refresh rates. Core to our approach are an approximate shadowing technique and an adaptive dithering technique, which allow us to cheaply render fully lit volumes at high resolutions and under a range of visibility conditions. We discuss the design decisions which enable our solver to run at interactive rates.
