A System for Interactive Sound Synthesis Based on Tree Simulation

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we proposes a system to generate environmental sounds from tree swaying based on a tree simulation. A position-based dynamics is used to simulate the real-time tree swaying, in order to obtain the timing of leaf collision and friction. For the collision sound, modal analysis is performed based on the voxel model made from a leaf shape to obtain the natural frequencies, and for the friction sound, a recursive frequency characteristic is reproduced using 1/f noise. The system can generate sound based on the simulation with various tree parameters, and reduce the time and effort required to record or synthesize sound which match computer graphics animations. As a result, the system enables simultaneous generation of both animation and sound.
