Soft Body Simulation using eXtended Position Based Dynamics

Overview

Academic prototyping project for soft body simulation using XPBD. Different constraint types will be implemented using Eigen for matrix computations and libigl for visualization and user interaction.

Short term roadmap

Constraint types

• edge length
• tetrahedral volume
• fem based

Dependencies

• C++17 compiler
• libigl

libigl is included in the project using CMake's FetchContent and pulls in Eigen, glfw, Dear ImGui and TetGen with it.
