A General Two-Stage Initialization for Sag-Free Deformable Simulations

ACM Transactions on Graphics (Proceedings of SIGGRAPH 2022), 41, 4, 2022

This is a Python implementation of initializating sag-free MPM simulation (https://graphics.cs.utah.edu/research/projects/sag-free-simulations/).

Naive initialization

Sag-Free initialization

Usage

Turn on the sag-free initialization by setting USE_SAGFREE_INIT as 1 in line34.

Dependencies

This demo depends on Taichi. You may follow its documentation for installation, or simply type pip install taichi under a Python 3 environment. This demo is tested under Taichi 1.0.4.

Run the Demo

python SagfreeElasticBeam.py
