Predictive-Corrective Incompressible SPH Simulation
Zihao Li, Samuel Johnson, Dixuan Yang
This work is based on Predictive-Corrective Incompressible SPH (PCISPH), which is an improvement of the original SPH simulation method by applying an additional prediction-correction loop to achieve the incompressibility as well as allowing larger simulation timesteps. In order to enhance the quality and stability of this simulation, we integrated concepts from other related papers such as enabling self-adjusted time steps, applying particle collision tests, using a more practical "cohesion-viscosity-curvature surface tension model", dealing with boundary particle issues result from insufficient neighbors, etc. Once we have the particles simulated, we render them using screen-space fluid rendering with curvature flow. This technique creates a screen space smooth mesh from the particles using a blurred depth map. It also creates a thickness map of the particles. Combining these two maps with realistic shading produces realistic rendering of water in real time.
Shallow Lava Flow Simulation
By Nate Bowditch (nbowditch)
Description: "Lava flow over a heightmap-based terrain is simulated using a simplified version of the shallow water equations. The project started out by implementing the paper Fast Hydraulic Erosion Simulation and Visualization on GPU by Xing Mei, Philippe Decaudin, and Bau-Gang Hu. In this paper, values such as the flow and height of fluid at each cell on a grid are stored on the GPU in the pixels of textures. These values are used to redraw the mesh of the fluid after each timestep as well as calculate how the fluid will move. To make this work for lava, heat energy is tracked across cells, and over time, heat energy slowly approaches the temperature of the environment. The average temperature between adjacent cells is made to be proportional to the cross-sectional area of the virtual pipe connecting the adjacent cells. This virtual pipe limits the flow between adjacent cells; thus, temperature is made to have an effect on the viscosity of the lava, where hotter lava is less viscous. To get the lava to be a realistic color, there is a simplified integration over wavelength energy values found via Planck's law. Hotter lava appears bright orange and cool lava appears dark red or black."
