description: This paper is devoted to the creation of an algorithm for modeling the interaction of airflows on a large area of grass. The propeller on the scene, which can have different directions, sets the airflow. The work sets the following goals: 1. Creating a mathematical model that describes the airflow. 2. Development of a parallel algorithm for processing the grass on the GPU in real time. Mathematical model of the airflow has been developed. The model is based on the representation of the propeller by ring sources and allows calculating the value of the airflow via the coordinates of the point relative to the propeller, taking into account the height of terrain. The developed technique for processing grass creates realistic animation of its interaction with airflows and dynamic objects in real time. Processing includes texturing, lighting, and dynamic distribution of grass over the landscape to improve visualization quality.
