SimSDF: Physically-Based Simulation with Signed Distance Field

This repository contains an implementation for the CS5643 final project, coded by Zichen Wang, Xilai Dai, and Barry Lyu.

Environment

The environment setup for this repository is fairly simple. Run
conda create sim-sdf
conda activate sim-sdf
pip install numpy taichi matplot

Code Structure

Here is a breakdown of the repository to facilitate better comprehension of our codes. The repository contains many folders, and each folder presents a scene using a certain approach--

Folders starting with sphere denote head-on collision experiment of two spheres;
Folders starting with many_spheres denote a scene of many spheres.
Folders ending with gt denote the ground truth using particle simulation;
Folders ending with mesh denote the baseline using mesh to approximate the sphere;
Folders ending with sdfdenote our method using SDF.

Inside each folder, we have the following files--
main.py is the primary entry pooint. It is also where the initial scene is delcared.
util.py combines configures with common functions.
scene.py contains the Scene class.
shape.py contains the supported object classes. Refer to the Object class as an interface for all objects.
gui.py implements the GUI.
maxsdf.py generates the illustrative figure shown above.
