The creation of visualization system for dynamics of dusty plasma particles on the basis of OpenGL

Abstract

In work the program allowing in a flexible dialogue mode to investigate structural, dynamic properties of dusty plasma on the basis of a computer method of langevin dynamics is described, and also visually to watch emergence of ordered structures in dust plasma. The program is developed in language of objectoriented programming of Delphi7 with use of graphic library OpenGL. The periodic grid with the cubic cell, filled with particles is considered. Animation visually shows that the particle leaving a cell through one of sides with a particular speed, gets to other cell, but thus the same particle with the same speed enters in this cell through a counter side. The user in an interactive mode observes driving of particles in a basic cell, thereby, having an opportunity visually to estimate its trajectory and a type of a potential energy of system depending on time. Also, control which using is included in the program, shift operators, turn, a full-screen mode, scaling transforms images.
