Abstract: 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.

Abstract: An apparatus and a method for expressing wetting and drying on an object surface are provided. The apparatus includes an adding water mark module adding new water on an object surface from a particle or a mesh representing water in outside environment, a wetting module considering water affinity of the object surface, a 2D fluid simulation module processing a flow of water particles in excess of a wet capacity of the object, and a drying module drying a drying wet portion after a predetermined time elapses. Moreover, a characteristic change of the object surface can be expressed, which is caused by water contact in the object surface interacting with water, and also water affinity can be expressed using a wetting capacity and a drying time. Therefore, detailed expression of water is possible when water exists in a scene, and various scenes with water can be depicted more realistically, which is a very important component of special effects.

Abstract: Provided are a system and method for simulating fluid particles having multi-resolution. In the method, given particle data expressing fluid is analyzed in an fluid particle analyzing module so that data for determining resolutions is obtained. A resolution of each of regions is determined using the obtained data in a resolution level determining module. Particles of each of the regions are reformed to particles corresponding to the resolution of each of the regions using the determined resolution of each of the regions in a fluid particle reforming module. Position data of fluid particles of a next frame is obtained after a simulation using the reformed particles in a multi-resolution fluid simulation module. Therefore, the fluid simulation having the high resolution can be performed in limited computing resources by applying different resolutions to each of the regions.
