This project is a straightforward GPU-based implementation of Jos Stam's

[Stable Fluids] in Unity.

[Stable Fluids]: https://www.dgp.toronto.edu/people/stam/reality/Research/pdf/ns.pdf

[WebGL Demo](https://keijiro.github.io/StableFluids)

## System Requirements

- Unity 6

## Project Structure

While this project uses URP, the following modules depend only on the Core

Render Pipeline shader library, making them compatible with any render pipeline

(Built-in/Universal/High-Definition).

### `Assets/StableFluids`

Contains Jos Stam's Stable Fluids implementation. Access the velocity field

texture via `FluidSimulation.VelocityField` for rendering or to apply external

forces.

### `Assets/Marbling`

Contains components for the marbling demo, which advects colors based on the

velocity field.
