    • A data management method of obtaining accurately the number of data satisfying a retrieval condition and the number of data not satisfying a retrieval condition is employed in a data management apparatus including: a storage device storing a plurality of data, each data having an attribute and an attribute value associated with each attribute; a display device; a control circuit for displaying on the display device a region for each attribute value of a certain attribute and a plurality of icons representing the plurality of data, respectively, on each region; and a circuit to retrieve data by a filter to which an attribute and an attribute value are related. The data management method includes the steps of displaying the plurality of icons on a region provided for every attribute value as to a certain attribute; generating a filter overlapping the region; moving or modifying the configuration of the filter on the region arbitrarily; entering a retrieval condition as to an attribute and an attribute value related to the filter; detecting whether the region has an overlapping section with the filter; and detecting data that meets the retrieval condition when the region has an overlapping section with the filter.

    • A method for generating a multisided patch in which the expression form of each boundary curve and topology of the curve network can freely be set, curve formulae can be simply input, and high continuity. By inputting data of boundary curves to multisided patch generator via editing means which generates and edits curves, and blending sweep surfaces in two stages, a free-form surface is generated as a surface interpolating them. That is, data of a plurality of boundary curves is inputted to multisided patch generator, each given curve is swept by sweeping means along the curves intersecting it to generate surfaces, and the surfaces are blended by blending means in two stages, thereby generating a free-form surface. Since the surface formulae can be defined on the basis of the curve formulae of the boundaries, topology of the curve network and the descriptive form of each curve can freely be set, so that the boundary curve formulae of a multisided patch can be simply input by directly drawing the curve shapes on defined two-dimensional planes. In addition, geometric continuity of the generated surface is high because continuity of the given curves is high.
    • 一种生成可以自由设置每个边界曲线的表达形式和曲线网络拓扑的多区块的方法,可以简单地输入曲线公式,并具有高连续性。 通过将生成和编辑曲线的编辑装置的边界曲线的数据输入到多段贴片发生器,并且将扫描表面混合在两个阶段中,生成自由曲面作为表面内插它们。 也就是说,多边界曲线的数据被输入到多片贴片发生器,每个给定的曲线被扫描装置沿着与其相交的曲线扫过以产生表面,并且表面通过混合装置分两个阶段共混,从而产生一个自由 形状表面。 由于表面公式可以根据边界的曲线公式定义,曲线网络的拓扑结构和每个曲线的描述形式可以自由设置,从而可以简单地输入多维贴片的边界曲线公式 直接在定义的二维平面上绘制曲线形状。 此外,由于给定曲线的连续性高,所以产生的表面的几何连续性很高。
