Methods, systems and computer program products pertaining to simulating liquid bodies are presented. The subject matter of this document can be embodied in a method that includes obtaining one or more data arrays representing low frequency spatial features of a simulated volume of liquid, and up-sampling the one or more data arrays to produce corresponding high resolution data arrays. The method also includes obtaining procedural data representing high frequency spatial features of a simulated liquid surface, and modifying the one or more high resolution data arrays using the procedural data to produce corresponding modified data arrays that reflect both the high frequency and the low frequency spatial features of the simulated volume of liquid.

High resolution simulation of liquids

A computer-implemented method for simulating a granular material includes removing, from a layer of granular material in a virtual domain defined by a data structure stored in a computer readable storage medium, a portion of the granular material in a closed region where the portion and a part of an object impacting the granular material are defined as occupying a same space. The method includes determining a value for a size aspect of the portion based on applying a numerical solver along an entirety of a boundary of the closed region. The method includes placing additional granular material along the boundary to create a shape resulting from the impact of the object. The method includes generating an image using the data structure, the image reflecting the impact of the object on the granular material in the virtual domain.
