Landscape design rendering is an important task in the field of computer graphics. In games and other applications, there is often a need to draw large open areas. The creation of these territories is a laborious task for a person, therefore, it is often partly or completely carried out by a computer. Thus, to use the landscape in computer graphics, it is necessary to solve the following tasks: its modeling or generation and visualization.
