Position Based Fluid Simulation

CSC417 Project
Hanlin Zhou, Long Ji

This project follows algorithms and methods from Position Based Fluids by Miles Macklin and Matthias Müller(2013).
Demos require 64-bit Python3 and taichi library version 0.7.0.
Demos run on GPU (CUDA) by default.
Can switch to CPU by changing "ti.init(arch=ti.gpu)" to "ti.init(arch=ti.cpu)".

2D Simulation:

-run Position_Based_Fluid.py
-Press 'A' and 'D' to control fluid movement.

3D Simulation: (no realtime 3D visualization available)

-run PBF3D.py
-Press 'A','D','W','S' to control fluid movement.
-switching to cpu mode not recommended.
-creates a sub-folder "./3d_ply" which stores outputs PLY files that can be rendered in other software. (Blender, Houdini)
-comment out line 362-366 if you do not want the PLY outputs.
