A toy fluid engine

A repo that tries to reimplement some fluid-related algorithm,

The project is based on Taichi, a programming language that embeds both GPU and CPU parralleled computing.

Dependency Installation

pip install taichi taichi_glsl

Fast Run

python exp_play_Euler.py --cfg mouse2d # use mouse to drag the fluid
python exp_play_Euler.py --cfg jet2d   # shot the jet from below
python exp_play_Euler.py --cfg jet3d   # 3D jet
python exp_play_Euler.py --cfg BMcq_jet2d # takes time

Feature:

Currently, we support

• Euler
• Material Point Method

In both 2D/3D. The 3D version is rendered with Taichi Three(Tina)

Reference

For implementation

• NVIDIA GPU GEMs,
• taichi official example
• Cornell_class_slides
• offcial tutorial
• Previous Eulerian Fluid Engine With taichi
