Methodology for virtual sound synthesis for graphical object interactions

초록

Modal synthesis procedures are extensively used in virtual reality applications to estimate the vibrations of rigid bodies and to identify the shapes of modes when subjected to an external force. Modal analysis involves the statistics of material parameters and damping factors. The damping functions are significant in virtual sound generation because the duration of oscillations depends on damping, i.e., how long the sound will be perceptible before fading out completely. The computed damping coefficients to be applied for synthesizing the subsequent virtual sounds when rigid bodies come in contact with each other in a virtual environment. In this study, we present a pipeline to generate virtual sounds for 3D object interactions in dynamic virtual envi-ronments.
