Fluid Animation Using Sketching, Diffusion-Reaction and Lattice Boltzmann Models

This work presents a methodology for two-dimensional fluid animation that is based on sketching techniques, along with diffusion-reaction equations and fluid simulation using the Lattice Boltzmann Method (LBM). In the initial stage, the framework converts the drawings made by the users into streamlines. From these lines it is generated a local velocity field, which is widespread throughout the flu...
