Simulation of the natural world is a rich and difficult research problem. The GAMMA group at UNC investigates a wide variety of techniques for efficient physically-based animation and simulation.

Recent projects include automatic simplification of articulated body dymanics, efficient cloth simulation using chromatic decomposition, simulation of hair dynamics, simulation of painting, simulation of lightning, and simulation of ice formation. Past projects include automatic simplification of particle systems, and fast penetration depth calculation using deformed distance fields.

• Cloth simulation using chromatic decomposition
• Adaptive Dynamics of Articulated Bodies
• Efficient, Error-Bounded Approximate Simulation for Quasi-Statics of Complex Linkages
• Paint simulation, including an interactive brush model, the dAb painting system, the IMPaSTo painting system, and an interactive viscous paint model.
• Physically based simulation, animation and rendering of lightning
• Hair Modeling Using Level of Detail Representations, Adaptive Grouping and Subdivision and Water and Styling Product Effects.
• Simulation of ice crystal growth using phase fields and a hybrid approach.
