PBD Taichi

Library for PBD and XPBD, aiming at including most type of constraints on mesh and tetrahedron.

• Cloth simulation
• Deformable simulaiton
• Complementary Dynamics
• Hash grid collision
• Rigid body simulation
• Rod

Environments

Python version 3.9

pip install taichi 
pip install usd-core
pip install meshio
pip install pillow
pip install glfw
pip install PyOpenGL PyOpenGL_accelerate

See results

Run scripts in test folder

For example:

python -m test.cloth_sim

1. Cloth

python -m test.cloth_sim

Constraints:

• Bending
• Length

2. Balloon

python -m test.balloon

Constraints:

• Bending
• Length
• Volume preserving

3. Particles Collision

python -m test.dem3d

Solve collision of large group of particles with hash grid

4. Neo-Hookean Deformable Objects

python -m test.fish_deform

Based on this paper and the live demo.

For comparison, there is a mass spring version.

python -m test.fish_spring

5. Complementary Dynamics

python -m test.fish_comp

Based on complementary dynamics and its modified PBD version.
