Water surface simulation summing simple sine functions in ThreeJS using vertex shaders

Finished at April 1, 2017

A height map is calculated dynamically summing simple sine functions

This is a simple surface ocean water simulation based on a sum of sine functions approach for calculate a height map that fits as a normal extrusion coefficient in a plane mesh and that dynamically calculates water surface orientation from GPU in a vertex shader. Visualization characteristics are provided by Jeremy Bouny water projects made in ThreeJS @jbouny/ocean . This Project could be considered a basic implementation of GPU gems chapter 1, named Effective Water Simulation from Physical Models By Mark Finch and Cyan Worlds.

2D SPH Water simulation in ThreeJS from CPU

Finished at May 25, 2017

Every water particle is represented as a green box of width and heigh h

This is a basic water body simulation based on the Smoothed Particle Hydrodynamic (SPH) method with leapfrog integrator for simulate water fluids in 2D from CPU using JavaScript and ThreeJS. The code was originally written in C by the Computer Science professor David Bindel at Cornell University as a parallel computing class exercise although this is a serial implementation (no parallel computing is involved).
The port from C to JavaScript was made in collaboration with @jorovipe97.
