Modeling Autumn Sceneries

Abstract

This paper presents a system for modeling autumn leaves covering vegetation and monuments. We simulate the coloring and aging process by a stochastic model that represents the probability of evolution of a leaf according to the characteristics of the environment. We distribute leaves over the ground by approximating their complex movement by trajectory templates such as fluttering, rolling and tumbling. Leaves stack onto the ground in successive layers so as to improve the collision detection step.
