Realistický model oblohy
The simulation of natural phenomena such as clouds, smoke, fire and water is one of the most important research areas in computer graphics. Clouds are an essential component of any outdoor virtual environment, they add an important element of visual detail without which the environment would feel unrealistic. But the complexity of cloud formation, dynamics, and light interaction makes cloud simulation and rendering difficult in real time. This paper describes current state of knowledge. In the first part I show meteorological definition of clouds and classification of the basic cloud types. The next part describes general technologies that have been used to model and render clouds. The main part of this paper shows a simulation technique, based on a numerical solution of the partial differential equation and Coupled Map Lattice.
