摘要： Provided are a system for generating a surface mesh surrounding particles on a 3D space. An implicit function module receives particle data containing three-dimensional location and radius data of the particles, grids the particles into rectangular parallelepiped shape, and generates implicit function data having implicit function value determining the surface at grid points. A mesh module generates a mesh through a pre-process of substituting the implicit function value of the gird point, where the implicit function value is defined, by zero when the a distance between a grid point where the implicit function value of the implicit function data and the vertex of the mesh is within a set distance. Accordingly, the system and method are useful for visualizing the results of particle simulations used in basic science and engineering. In particular, the system and method can generate high-quality mesh in computer graphics of fluid simulation using the particles.
