Cellular Automata Fluid Simulation

This is an implementation of fluid/liquid dynamics using Cellular Automata. The purpose of this project is to show how dramatic is the difference of computing the evolution of cells with two approaches: naive grid cell evolution in CPU, and compute shaders in GPU.

How to play

• The elements that can be drawn on the canvas are:
  • Ground NumKey 1
  • Water NumKey 2
  • Acid NumKey 3
• Increase the size of the brush with the mouse wheel
• Generate a new procedural cave map with N
• Clean the map with C
• Rotate the map with R
• Quit the program with Esc

How to build
