Animating Corrosion and Erosion
In this paper, we present a simple method for animating natural phenomena such as erosion, sedimentation, and
acidic corrosion. We discretize the appropriate physical or chemical equations using finite differences, and we use
the results to modify the shape of a solid body. We remove mass from an object by treating its surface as a level set
and advecting it inward, and we deposit the chemical and physical byproducts into simulated fluid. Similarly, our
technique deposits sediment onto a surface by advecting the level set outward. Our idea can be used for off-line
high quality animations as well as interactive applications such as games, and we demonstrate both in this paper.
