Rasterization-Based Liquids

Martin Guay

4.1 Overview

Rasterization pipelines are ubiquitous today. They can be found in most of our

personal computers as well as in smaller, hand-held devices—like smart phones—

with lower-end hardware. However, simulating particle-based liquids requires

sorting the particles, which is cumbersome when using a rasterization pipeline.

In this chapter, we describe a method to simulate liquids without having to sort

the particles. Our method was specifically designed for these architectures and

low shader model specifications (starting from shader model 3 for 3D liquids).

Instead of sorting the particles, we splat them ...
