Abstract: Provided are a sub-particle scale turbulence simulation method for SPH fluid, and a system and recording medium for the method. In the present disclosure, by combining a multi Eulerian grid with a SPH system, various Eulerian grids are combined with the SPH system while the vorticity of particles is efficiently calculated, which allows firm detection of a deformation region. For this reason, along with the flexibility and simplicity of the multiple grids system, the present disclosure may be easily expanded to a broad spectrum in aspects of time and space. Moreover, the present disclosure may express multi-level vorticity, which could not be expressed by an existing SPH system, and give a stable and visually satisfactory result.

Abstract: Provided are a method, an apparatus and a system for dense graph simplification, and a recording medium for the same. The method includes receiving an original graph and extracting a plurality of salient points, which minimize a cost representing a greatest vertical distance between the original graph and each of a plurality of lines connecting two data points in a designated region on the original graph; and outputting a simplified graph in which the extracted salient points are connected. Thus, optimal results are ensured in dense graph simplification, and interactive control is allowed for a user.

Abstract: Provided are a rendering method for monoscopic, stereoscopic, and multi-view computer generated imagery, a rendering system, and a recording medium thereof. When rendering an image sequence having a plurality of consecutive frames, standard frames are initially selected and rendered, and then normal frames between the selected standard frames are rendered by receiving rendering information of a preceding frame in time in a channel and rendering information of a subsequent frame as transfer functions, thereby reducing rendering time and rendering error. If the image sequence is a multi-channel image sequence for stereoscopic and multi-view imagery, rendering information of a simultaneous frame in a neighboring channel can be additionally received as a transfer function, thus allowing more efficient rendering.
