ABSTRACT:
Thin films or sharp edges in a fluid body are expressed in the display of a particle-based fluid-body simulation. The surface construction method is a method applied to a method for rendering calculation results on the screen of a display device using data that are obtained by calculation of a fluid-body simulation based on a particle method executed by a CPU or the like. The method has a first stage of allocating a concentration sphere to a particle that is a calculation object and computing an implicit function curved surface, and computing a plurality of base vertices (V0) for creating a fluid-body surface by the implicit function curved surface; and a second stage that is executed at least one time for adjusting a surface sharpness for each of the plurality of base vertices (V0) for creating the fluid-body surface that is computed in the first stage.
