In this paper. we propose an efficient sound propagation and remapping technique based on geometry to enhance immersive sound effects in virtual environments. and suggest a method to interactively represent sound by considering the altitude and slope of the terrain. The proposed technique can represent real-time patterns of sound such as waves and flows of sound. https://www.roneverhart.com/Polly-Pocket-Polly-Lila-Tropicool-Pineapple-Wearable-Purse-Compact/
