Simulating an arbitrary number of particles

摘要

A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes obtaining first data corresponding to a first simulation of matter in a space domain. The method also includes performing, using the first data, a second simulation that produces second data representative of particles in the space domain. The method also includes rasterizing the second data representative of the particles as defined by cells of a grid, wherein each cell has a common depth-to-size ratio, and, rendering an image of the particles from the rasterized second data.

1. A computer-implemented method comprising:
obtaining first data corresponding to a first simulation of fluid matter in a Cartesian space domain, the first data produced from a globally coupled fluid model; defining a three-dimensional (3D) grid of cells to represent at least a part of the space domain, wherein the 3D grid of cells forms a frustum-shaped perspective grid; identifying a first plurality of the cells of the 3D grid of cells that contain components of the fluid matter according to the first data; subdividing the identified cells into a plurality of subcells; performing, for each of the plurality of subcells, using the first data, a second simulation of the fluid matter that produces second data representative of physical properties of the fluid matter in the subcells, the second simulation being particle-based; for each subcell, compressing particle simulation information from the second data to produce at least one value for each of a second plurality of cells of the 3D grid; and storing the values for each of the second plurality of cells in a retrievable form.
