Device for aiding the production of a mesh, comprising a first data structure storing first numerical data defining a surface to be processed, a partitioner (304;306;318) calculating three-dimensional work cells on the basis of given initial points, each of these work cells being associated with a point in space, a tiling tool (302;318) actuating the partitioner (304;306;308) with a first set of initial points, defined with respect to the surface to be processed, so as to obtain a first set of work cells, an evaluator (310;312;318), calculating a cumulative quantity representing the sum of the moments of the points of the work cells with respect to their respective associated points, and an optimizer (318;314) iteratively actuating the tiling tool and the evaluator with on each occasion a set of initial points drawn from the previous sets, according to a rule calculated so as to tend to minimize said cumulative quantity. The moments are determined according to a chosen nonnative function, of order higher than or equal to two and/or according to an adaptation matrix representing an anisotropy field. |
