    • Device for aiding the production of a mesh, includes storing first numerical data defining a surface to be processed, a partitioner calculating three-dimensional work cells given initial points, each work cell associated with a point in space, a tiling tool actuating the partitioner with a first set of initial points, defined with respect to the surface, so as to obtain a first set of work cells, an evaluator calculating a cumulative quantity representing the sum of the moments of the points of the work cells with respect to their associated points, and an optimizer iteratively actuating the tiling tool and the evaluator with a set of initial points drawn from the previous sets, according to a rule calculated to minimize said cumulative quantity. The moments are determined by a chosen nonnative function, of order higher than or equal to two and/or according to an adaptation matrix representing an anisotropy field.
    • 用于协助生产网格的设备包括存储定义要处理的表面的第一数字数据,分配器计算给定初始点的三维工作单元,与空间点相关联的每个工作单元,启动分隔器的平铺工具, 相对于表面定义的第一组初始点,以便获得第一组工作单元,评估者计算表示工作单元的点相对于其相关点的时刻之和的累积量 并且优化器根据计算出的最小化所述累积量的规则,迭代地使用来自先前集合的一组初始点来激活平铺工具和评估器。 力矩由选择的非相关函数确定,阶数高于或等于2,和/或根据表示各向异性场的适应矩阵确定。
