A Ray Tracing and FEM-based Simulation of Optical Waveguide-based Tactile Sensors

Author: Shao, Qi
Course: Physics-Based Simulation (Spring 2023)
Instructor: Prof. Tao Du
Institution: Tsinghua University

This repository contains a 2D simulation project demonstrating the use of ray tracing and finite element methods (FEM) for modeling optical waveguide-based tactile sensors. The project allows users to visualize and interact with a simulated tactile sensor.

Dependencies

This project requires the following packages:

• pygmsh==7.1.17
• taichi==1.5.0

Platform

The project was developed and tested on Windows 11 with the CUDA backend for GPU acceleration.

Running the Simulation

To run the simulation, use the following command:

python main.py

Demonstration

1. Demo 1: Shows the adjustment of the optical waveguide shape.
   

2. Demo 2: Shows real-time interaction with objects generated using the mouse.
