    Abstract: A method for calculating a force acting on an interface between immiscible fluids in an SPH (Smoothed Particle Hydrodynamics) based fluid simulation includes: calculating a force caused by viscosities of the fluids; calculating a force caused by pressures of the fluids; calculating an external force applied to the fluids from outside; and calculating an interactive force caused by interaction between the fluids. The force acting on the interface between the immiscible fluids are obtained by using sum of the force caused by the viscosities, the force caused by the pressures, the external force and the interactive force. The interactive force is a surface tensional force calculated based on a pressure acting on the interface between the fluids.

    Abstract: The present invention relates to an apparatus for time-coherent texture synthesis including a texture preprocessor for receiving as input information a 2D texture image and a 3D triangular mesh, and preprocessing the 2D texture image in a form suitable to rapid searching, a vector field generator for defining a vector field on a 3D surface of the 3D triangular mesh, a color search unit for finding a color of each edge of a triangle having the defined vector field in consideration of a previous frame, and a texture synthesizer for determining texture coordinates of the triangle using the found colors. The texture preprocessor further receives information regarding a size of the texture to be synthesized and an initial vector field orientation.

    Abstract: PURPOSE: An apparatus and a method for searching neighboring particles based on temporal coherence are provided to minimize times required for searching the neighboring particles. CONSTITUTION: Initial neighboring target particles are set(S201). Mutual influence to the initial neighboring target particles is calculated(S203). The positions and the information of the particles are updated according to the mutual influence of the neighboring target particles. If a neighboring condition is satisfied, neighboring information is stored(S205, S207). If the calculation process with respect to all target particles is completed, the positions and the information of the particles are updated(S209, S211). Neighboring particles of a previous time are set as neighboring particles.

    Abstract: PURPOSE: A device and a method for extracting a correspondence relation among aerial images are provided to form a correspondence relation between images in a place without regional features by using a macroscopic relation of buildings in aerial images of a city. CONSTITUTION: A device for extracting a correspondence relation among aerial images comprises a line extracting unit(70), a line direction determining unit(80), a building upper area extracting unit(90), and a correspondence relation extracting unit(120). The line extracting unit extracts lines corresponding to buildings from two or more aerial images. The line direction determining unit respectively defines directions of the liner as an X-axis, a Y-axis, and a Z-axis based on the coordinate system of 2D images. The building upper area extracting unit extracts a building upper area of a square formed by rotating the lines corresponding to the X-axis to a horizontal direction of the 2D images and the lines corresponding to the Y-axis to be parallel with a vertical direction of the 2D images. The correspondence relation extracting unit extracts a correspondence relation between the aerial images by respectively comparing the building upper area extracted from the aerial images.
