--- _id: '3762' abstract: - lang: eng text: 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. article_processing_charge: No author: - first_name: Christopher J full_name: Wojtan, Christopher J id: 3C61F1D2-F248-11E8-B48F-1D18A9856A87 last_name: Wojtan orcid: 0000-0001-6646-5546 - first_name: Mark full_name: Carlson, Mark last_name: Carlson - first_name: Peter full_name: Mucha, Peter last_name: Mucha - first_name: Greg full_name: Turk, Greg last_name: Turk citation: ama: 'Wojtan C, Carlson M, Mucha P, Turk G.
