Abstract
In this paper, we present a particle-based method for visually simulating lava flows. Employing our developed particle-based simulation models of viscous fluid dynamics and heat transfer, this method realizes the visual features of lava flows: lava flows broaden like a fan form; the viscosity of lava changes according to its temperature; cool downed lava gets hard (hard lava is called crust); the color of lava changes according to its temperature; crust is dark; lava of high temperature run out by breaking crust; etc.
