摘要： One embodiment of the present invention sets forth multigrid generation technique which enables accurate simulations of large scale three dimensional (3D) fluid volumes. A model of the fluid to be simulated is represented using a cell grid. The generated multigrid provides a hierarchy of increasingly coarser representations of the model that are used by a pressure solver. Eulerian simulation techniques require solving a linear system to determine pressure values for each cell within the cell grid. Different levels of the multigrid are then used to compute the pressure values for different regions of the model, maintaining accuracy near the surface of the fluid while simplifying the computations. The accurate pressure values ensure that the simulation produces detailed features of the water movement. Additionally, the multigrid pressure solver may be optimized for execution by a graphics processor.

摘要： One embodiment of the present invention sets forth a geometric multi-grid technique which enables accurate simulations of three dimensional (3D) fluid volumes. A model of the fluid to be simulated is represented using a cubic cell grid. The geometric multi-grid is generated to provide a hierarchy of increasingly coarser representations of the model that are used by a fluid pressure solver. During fluid simulations, the linear complementarity problem (LCP) resulting from discretizing the Poisson equation, subject to separating solid boundary conditions, is solved using the geometric multi-grid. Visual artifacts such as liquid sticking to a bounding surface are minimized and the computations performed to solve the LCP are simplified.

摘要： One embodiment of the present invention sets forth an Eulerian fluid simulation technique which enables real-time simulations of large scale three dimensional fluid volumes that include free surface water. A hybrid grid representation composed of regular cubic cells on top of a layer of tall cells is used to reduce computation time. Water above an arbitrary terrain can be represented without consuming an excessive amount of memory and compute power, while focusing simulation effort on the area near the surface of the water to produce accurate results. Additionally, the grid representation may be optimized for a graphics processor implementation of the fluid solver.
