Procedural modeling of water caustics and foamy water for cartoon animation

Abstract

We propose a method for procedural modeling and animation of cartoon water effects such as water caustics and foamy water. In our method we emulate the visual abstraction of these cartoon effects by the use of Voronoi diagrams and the motion abstraction by designing relevant controlling mechanisms corresponding to each effect. Our system enables the creation of cartoon effects with minimal intervention from the animator. Through high-level initial specification, the effects are animated procedurally in the style of hand-drawn cartoons.

Cartoon Water Rendering with Foam and Surface Smoothing

“…Yingst et al method [11] emulate sea foam dissipation with a precomputed dither array, on a method suitable for real-time environments, but produces pixelation as the camera approaches the liquid surface. Liao et al [12] presents another method, consisting of procedural modeling of water caustics and foam employing a texture generated with Voronoi diagrams. Both methods don't require a physical simulation.…”

“…Methods to render non-photorealistic water were recently developed, but they are either not meant for real-time applications [7] [8], don't use fluid simulation [9] or don't take into account effects like foam and spray [10]. Although techniques to generate foam and spray specifically for cartoon water were developed recently, they rely on preloaded textures and procedural methods instead of on the simulation itself [11] [12].…”

Molecular Dynamic Simulation Study on Thermal Decomposition Mechanism of Cellulose

“…Based on the previous experimental results, the possible formation pathways of major products through reactions of all kinds of molecular fragments were analyzed. of cellulose pyrolysis mainly focused on experimental studies to explore the rate of tar, gases and coke in different conditions based on B-S model [9][10][11] . The thermogravimetric analyses were also performed to confirm pyrolytic characteristics of cellulose and the kinetic models of cellulose pyrolysis were constructed to obtain kinetic parameters 12,13 .…”
