Digital Animation of Power-Snow Avalanches
Filipe Nascimento, Fabricio S. Sousa, Afonso Paiva Powder-snow avalanches are natural phenomena that result from an instability in the snow cover on a mountain relief. It begins with a dense avalanche core moving fast down the mountain. During its evolution, … Continue reading

Unified Pressure, Surface Tension and Friction for SPH Fluids
Timo Probst, Matthias Teschner, Fluid droplets behave significantly different from larger fluid bodies. At smaller scales, surface tension and friction between fluids and the boundary play an essential role and are even able to counteract gravitational forces. There are quite … Continue reading

Corotational Hinge-based Thin Plates/Shells
Qixin Liang We present six thin plate/shell models, derived from three distinct types of curvature operators formulated within the corotational frame, for simulating both rest-flat and rest-curved triangular meshes. Each curvature operator derives a curvature expression corresponding to both a … Continue reading
