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.

• read my PhD thesis
• read the SIGGRAPH'97 technical sketch
• read a draft technical report in English (packed with gzip,  1.54 Mb, Letter)
