Windy Trees: Computing Stress Response for Developmental Tree Models

Sören Pirk, Till Niese, Torsten Hädrich, Bedrich Benes, Oliver Deussen We present a novel method for combining developmental tree models with turbulent wind fields. The tree geometry is created from internal growth functions of the developmental model and its response to external stress is induced by a physically-plausible wind field that is simulated by Smoothed […]

SPGrid: A Sparse Paged Grid structure applied to adaptive smoke simulation

Rajsekhar Setaluri, Mridul Aanjaneya, Sean Bauer, and Eftychios Sifakis We introduce a new method for fluid simulation on high-resolution adaptive grids which rivals the throughput and parallelism potential of methods based on uniform grids. Our enabling contribution is SPGrid, a new data structure for compact storage and efficient stream processing of sparsely populated uniform Cartesian […]

Coupling Hair with Smoothed Particle Hydrodynamics Fluids

Wei-Chin Lin We present a two-way coupling technique for simulating the complex interaction between hair and fluids. In our approach, the motion of hair and fluids is simulated by evaluating the hydrodynamic forces among them based on boundary handling techniques used in SPH (Smoothed Particle Hydrodynamics) fluids. When hair makes contact with fluids, water absorption […]
