Fluid simulation

My CPU implementation of fluid based on what is described in GPU Gems.

Renderings

Normal	Multiply velocity by scalar after advection

How to run on linux

Make sure libsdl2 installed. For debian based OS: sudo apt update && sudo apt install libsdl2-dev -y
Make sure g++, cmake and make are installed
mkdir build && cd build && cmake .. && make && ./fluid

Notes

Still need to implement boundary conditions
