PBF3D

This repository is the implementation of PBF (Postion Based Fluid) based on taichi, and with help of particle2obj tool in fluid-engine-dev to make particles to mesh, finally use blender to render animation.

Dependencies

taichi			(tested with 1.5.0)
opencv-python	        (tested with 4.5.5)

blender			(tested with blender 3.6.0-usd.200.0)

Overall process

1. first run pbf3d.py to get particles' position and save to local (the file extension should be xyz);
2. run particle2obj.py to generate mesh per frame (you can adjust the kernel_size as needed);
3. run animate.py in blender, this is a blender script to import mesh and generate animation;
4. use blender to render each frame of the image and save local;
5. run pic2vedio.py to make images to vedio;
