HTML5 Canvas Fluid Solver

==========================

A Simple fluid solver implementation in javascript.

A live demo can be found [HERE](https://topaz1008.github.io/canvas-fluid-solver).

The demo uses [lil-gui](https://github.com/georgealways/lil-gui) for the GUI.

Simulates the [Navier–Stokes](https://en.wikipedia.org/wiki/Navier-Stokes_equations) equations for incompressible fluids.

Largely based on Jos Stam's paper [Real-Time Fluid Dynamics for Games](https://www.dgp.toronto.edu/people/stam/reality/Research/pdf/GDC03.pdf).

The density field is rendered on an off-screen bitmap and blit'ed to the canvas for performance reasons.

The code is commented as best I could where ever I felt it was necessary.

The best reference is the original paper which is still online and contains a very clear explanation of the solver and methods it uses. It also contains a complete C implementation of the solver.

If the original paper ever goes offline I have a copy of it [here](https://github.com/topaz1008/canvas-fluid-solver/blob/master/doc/GDC03.pdf).

Other implementations I've looked at while making this. (these links are very old and are dead and/or insecure so proceed at you own risk)

Running

---------

Just open `index.html` in your browser or see the live demo [HERE](https://topaz1008.github.io/canvas-fluid-solver).

Wishlist

---------

* Add internal grid boundaries.

* Maybe think about considering thinking about a 3D implementation ;)
