Time varying hierarchical
Part of my PhD work consisted in exploring
how methods like hierarchical radiosity developed for global illumination
simulations can be applied to acoustic simulation. In that context I proposed
an extension of the existing algorithms in order to handle time-varying
energy exchanges. I addressed the problems of :
representing a time-varying `sound radiosity
solution' encoding global specular and diffuse reflections
optimizing the calculations by using a hierarchical
representation and achieving a `time-compression'
taking phase into account
auralizing the obtained solution.
