3D Gaussian Splat for Point Cloud Generation in Physics-Driven MPM Simulations
Abstract
This project aims to bridge the gap between real-world phenomena and computational physics simulations by converting video data of dynamic events, such as granular column collapses or dam breaks, into point clouds in real time using Gaussian splatting techniques. The generated point clouds will then be utilized in Material Point Method (MPM) simulations to model and understand these complex scenarios' underlying physics accurately. This approach will integrate with the CB-Geo MPM project, focusing on rendering natural hazards like landslides with an in-situ visualization interface. The project holds high priority due to its potential to enhance predictive modeling and digital twin reconstructions of natural disasters, contributing significantly to computational geotechnics and disaster management.

Motivation
Current techniques for modeling natural hazards and other dynamic events often rely on static datasets that do not capture the full scope of real-world variability. This project aims to create more dynamic and accurate digital twins of natural hazards by leveraging real-time video data and converting it into point clouds for MPM simulations. This method will enable the prediction and analysis of complex phenomena with unprecedented detail and fidelity.
