This project releases the educational C++ code used at SIGGRAPH 2016 Course "Physically Based Sound for Computer Animation and Virtual Environments".

There are two sub-projects, IsoStuffer and ModalSound.

IsoStuffer is an implementation of [Labelle and Shewchuk 2007]. It provides the functionality to construct a tetrahedral mesh from a water-tight triangle mesh.

ModalSound is a demostration of synthesizing rigid body sounds using the modal sound model. It includes the code of computing stiffness and mass matrices from a volumetric mesh and use the precomputed acoustic multipole coefficients to evaluate the acoustic transfer values at runtime.
