构造规则

In ACIS, function can be usedto form law, then the law would be used to produce curve.

在ACIS 造型工具中，可以利用函数来构造规则，然后利用规则来直接产生曲线，利用曲线按照一定的方式来产生面，然后将面按照一定的路径扫略来生成实体；本章就针对生成曲线的函数加以讨论，利用遗传算法的相关理论进行编码和进化操作，然后由用户对产生的子代进行评价，从而产生形式多样的子代实体。

Firstly, a spherical mesh with regular subdivision connectivity is constructed to partition the spherical domain into some small regions. Then the region, which contains the query point p, is found according to the position of p and selected as the search area for locating p. During the point location, the barycentric coordinates are used to extract local heuristic information about the location of p so as to find the shortest path from the start triangle to the target one containing p.

通过构造规则子分网格将原始球面网格区域划分成若干具有子分层次关系的查询小块；在进行查询前，根据查询点p的位置找到它所在的小块作为搜索区域，从而极大地缩小了查询范围；在查询过程中，根据重心坐标所包含的启发信息，选择一条从初始搜索三角形到目标三角形的最短查询路径。

Concretely, starting from a short sequence primal masks possessing Hermite interpolation properties, a necessary and sufficient conditions such that primal masks satisfies the preassigned order of sum rules are established, then a dual masks with short support, symmetry and any preassigned order of sum rules is constructed, it follows that two multiscaling functions are obtained and then multiwavelets and dual multiwavelets are derived. From which, a general design framework is obtained for constructing biorthogonal multiwavelets system with multiplicity 2r associated with Hermite interpolation functions.

Earthworks zero line is determined by constructing the spatial gridding curved surface model of the original terrain and the field leveling design terrain by digital elevation mode. The DEM data of original terrain are obtained by actual measurement. The mathematical correlation is deducted to demonstrate the relationship between the coordinates of any point on spatial line and the direction cosine by the spatial linear equation. DEM data obtaining program is compiled by Fortran9.0 and it is applied automatically to obtain the DEM data of field leveling design terrain.
