The article presents a program for animating the system of interacting flexible macroscopic objects and a liquid medium. Three-dimensional animation is carried out based on the simulation of physical phenomena. Its main task is faithful rendering of the dynamics of the objects present in the animation. Visualization is an important element of the animation program, but it has been significantly simplified by transferring its basic tasks (covering and shading) to graphic libraries. The simulation techniques used (particle and cellular automata method), detection and collision handling of objects were presented. In order to obtain faster animations, the program has also been implemented in a distributed version on a UNIX network of workstations.Downloads
