摘要： A method for constructing a triangular mesh surface of a point cloud includes constructing triangles according to point cloud data, determining seed triangles from the constructed triangles. The method further includes selecting triangles that share a side with a determined seed triangle from the constructed triangle, determining a specific triangle having the biggest dihedral angle with the determined seed triangle and the biggest angle opposing the shared side of the determined seed triangle. The method also includes repairing holes formed by the specific triangles if the all specific triangles have been determined, adjusting a normal vector of each specific triangle, and outputting a triangular mesh surface constructed by the adjusted triangle.

摘要： An adaptive weighting method for layout optimization differentiates different priorities by assigning the weight of a higher priority (pi) to be multiple of the weight of a lower priority (pi−1) where W(pi)=mi % W(pi−1. To avoid numerical imprecision, this method keeps the total cost in the objective function within a trustable range by scaling the initial weights in the objectives, while maintaining relativity, to produce the scaled weights.

摘要： A method for rotating a mechanical arm receives origin position parameters and final position parameters of the mechanical arm. A computer determines a position that an end joint of each of sections arrives after each iteration according to the origin position parameters and the final position parameters. The computer calculates a distance between the current position and the final position of the end joint of each of the sections and obtains a minimum distance. The coordinates of the end joint of each of the sections corresponding to the minimum distance is calculated. The computer drives each of the end joints to rotate to the calculated end joint coordinates corresponding to the minimum distance.

摘要： A method of polygonal area design rule correction for use in an electronic design automation tool for governing integrated circuit (IC) design layouts using one-dimensional (1-D) optimization, with steps of analyzing IC design layout data to identify violating polygons, partitioning violating polygons into rectangles in a direction of optimization, formulating an area constraint for each violating polygon to formulate a global linear programming (LP) problem that includes each constraint for each violating polygon and solving the global LP problem to obtain a real-valued solution. A next LP problem is created for each area constraint, and solved. The creating a next and solving the next LP problem and solving are repeated until the last “next LP problem” is solved using constraints and objectives representing sums or differences of no more than two optimization variables.

摘要： A system and method are disclosed for legalizing a flat or hierarchical VLSI layout to meet multiple grid constraints and conventional ground rules. Given a set of ground rules with multiple grid constraints and a VLSI layout (either hierarchical or flat) which is layout-versus-schematic (LVS) correct but may not be ground rule correct, the system and method provide a legalized layout which meets the multiple grid constraints while maintaining LVS correctness and fixing the ground rule errors as much as possible with minimum layout perturbation from the input design. The system and method support multiple grid pitch constraints for hierarchical design, and provide for LVS correctness to be maintained while an on-grid solution possibly with some spacing violations.
