Modeling Realistic Water and Fire

An overview of the latest techniques on computer graphics to model realistic water and fire is given. These fluid models are based on a simplification of the Navier-Stokes equations. Some of the most important applications represent real life problems solving as water flood, real fire situation, firemen training and others. Regarding water modeling, there are compared the different approaches, volume modeling or surface modeling. Situations as the immersion of an object into water are analyzed and the physical characteristics of water, such as light reflection/refraction are mentioned. In fire modeling the physical characteristics are analyzed, but also the chemical contribution for a more accurate model of fire, which includes smoke and radiance. The two different models are compared, from the point of view of both having a fluid like movement, as implicit surface models and particle systems employed in these analyzed approaches.
