– Interactive Sound Simulation and Rendering
Wednesday 27th by Dinesh Manocha
Extending the frontier of visual computing, sound rendering utilizes sound to communicate information to a user and offers an alternative means of visualization. By harnessing the sense of hearing, audio rendering can further enhance a user’s experience in a multimodal virtual world and is required for immersive environments, computer games, engineering simulation, virtual training, and designing next generation human-computer interfaces.
In this talk, we will give an overview of our recent work on sound synthesis and sound propagation. These include generating realistic physically-based sounds from rigid body dynamics simulations and liquid sounds based on bubble resonance and coupling with fluid simulators. We also describe new and fast algorithms for sound propagation based on improved wave-based techniques and fast geometric sound propagation. Our algorithms improve the state of the art in sound propagation by almost 1-2 orders of magnitude and we demonstrate that it is possible to perform interactive propagation in complex, dynamic environments by utilizing the computational capabilities of multi-core CPUs and many-core GPUs. We will also demonstrate applications to design of next-generation musical instruments, computer gaming, room acoustics, and outdoor sound propagation.

– Towards patient specific biophysical modeling : application to cardiology
Thursday 28th by Hervé Delingette.
Therapy training and planning often require to simulate the physics and the physiology of the human body in a patient specific manner but with different objectives and constraints. While interactive computational efficiency is often required to develop interactive medical simulators for therapy training, accurate models compatible with clinical constraints must be developed for therapy planning. In this presentation, I will outline the challenges involved when creating biophysical models from medical images for both therapy training and planning. A specific focus will be given on the efficient and realistic simulation of soft tissue deformation which combines elements of geometry, finite element modeling and physics. Several software pipelines will be presented linking medical images to patient specific models in the context of cardiac therapies.
Hervé Delingette is currently a research director in the ASCLEPIOS research team at the INRIA research center in Sophia Antipolis. He received in 1989 a Master degree and in 1994 a PhD degree from the Ecole Centrale des Arts et Manufactures de Paris, (France) and was habilitated in 2006. From 1989 until 1992, he was a Visiting Scientist at the Robotics Institute of Carnegie Mellon University (CMU) and the Human Interface Laboratory of Nippon Telegraph and Telephone (NTT). His research interests are in the fields of medical image analysis, image segmentation, soft tissue modelling, surgery simulation and computational models of the human body. He authored more than 60 journal papers in those fields and co-chaired the First Symposium on Surgery Simulation and Soft Tissue Modelling in 2003 and the fifth international conference on Functional Imaging and Modelling of the Heart in 2009.
