    • A surface texture expression system and a method thereof for performing a mixing expression of a surface texture are provided to store given surface texture information in a form in which the capacity is relatively small and a form which is high-capacity source data. A materials information preprocessor(100) converts surface material feeling information inputted through a user input device into a B-spline volume form. A sampling information preprocessor(200) generates sampling information which is in proportion to the texture information transformed through the material information preprocessor. A surface materials renderer(300) renders the surface materials renderer by using the texture information put through the sampling information.

    • The invention relates to a boundary smoothing method of a geometrical figure using a terminal in which a smoothing operation on the boundary of the given geometrical figure is defined using sweep and unsweep operation in a process for processing the boundary of the geometrical figure using CAD system or graphic tool, thereby computing and processing the boundary at a high speed with good performance the present invention provides a boundary smoothing method of a geometrical figure that is an important geometry operation, using a terminal. The boundaries of the geometrical figure are smoothed by using the sweep and unsweep operation without a complicated mathematical operation on the boundaries of the geometrical figure, and without being subject to a step of removing a self-cross or intercross. This method allows a user to designate and control an application region of the smoothing operation and a smoothing degree. Also, the method of the present invention can be easily realized by software. Since the realized software has a high performance, if it is combined with the current CAD system, graphic tool or the like, more enhanced effect can be obtained.

    • PURPOSE: A sweep-envelope and line-sweep computation method for general sweep boundary is provided to calculate the line-sweep of corresponding line segments, approximate boundary extraction, and extract the general sweep boundary on a 2-dimensional plane. CONSTITUTION: Two objects are approximated as polygons having the same number of vertexes(801). After start points of two polygons are searched(802), the start points are started and line-sweeps are calculated to corresponding two line segments in a clockwise direction(803). If the number of line segments exist in the polygons, the number of line-sweep is generated and the generated line-sweeps are added to two polygons through a union arithmetic for obtaining a sweep region(804).
    • 目的:提供一般扫描边界的扫描包络线扫线计算方法,以计算相应线段的线扫,近似边界提取,并提取二维平面上的一般扫描边界。 构成:两个对象被近似为具有相同数目顶点的多边形(801)。 在搜索两个多边形的开始点之后(802),起始点开始,并且沿顺时针方向对相应的两个线段计算行扫描(803)。 如果在多边形中存在线段的数量,则生成行扫描的数量,并且通过用于获得扫描区域的并集运算将生成的行扫描添加到两个多边形(804)。
