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
