A system and method for facilitating moving particles in a virtual space use depth information that reflects distances of objects in a virtual space to either a ground level or a viewpoint. The depth information may be stored in a set of information. The system detects collisions of particles and other objects based on the depth information, on a frame-by-frame basis.

Surface features might represent features of a virtual fluid and a method might include obtaining a digital representation of the virtual fluid defined at least in part by an implicit surface, obtaining a digital representation of a collection of points defined relative to the implicit surface whereat the surface features are to be determined. A point of the collection of points might have associated therewith a plurality of attribute values specifying a property of the surface features. For an input point, a corresponding implicit surface point might be determined, along with, for the corresponding implicit surface point, a subset of the points within a search region. Interpolated attribute values might be obtained from attribute values associated with points of the subset, and a surface displacement value computed from interpolated attribute values. A dataset corresponding to the surface features might be generated.

An electronic apparatus performs a method of simulating visual effect of avalanche of media. The method includes: interpolating particle information of the media to a grid; simulating advection of fluid from the media; applying a computed drag force to the interpolated particle information on the grid and to the simulated advection of the fluid; interpolating updated particle information from the grid; simulating fluid projection from the media; determining whether a fluid generation condition is satisfied; in response to the determination that the fluid generation condition is satisfied: generating additional fluid from the media; and applying a fluid decaying scheme.

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.
