Teilchensystems
Teilchensystems (German for "particle systems") are frameworks used to model and simulate large numbers of small discrete elements—particles—and their collective behavior. The concept appears in several fields, most notably computer graphics, fluid and aerosol modeling, statistical physics, and crowd simulation. In computer graphics, Teilchensystems generate visually complex phenomena such as fire, smoke, rain, dust, and explosions by evolving many simple particles according to rules for motion, forces, lifetimes, and visual attributes. In physics and engineering, they serve as numerical or conceptual tools for studying granular media, colloids, aerosols, and molecular ensembles.
Typical components of a Teilchensystem include particle state variables (position, velocity, mass, age), emission mechanisms, interaction
Optimizations such as spatial partitioning, level-of-detail, and GPU acceleration help manage performance when simulating millions of
