The method comprises modeling the stack within a computer simulation as a set of associated primitives with associated constraints thereto in the memory, wherein the stack comprises a plurality of layers and wherein each layer comprises at least one primitive. The method further comprises estimating a height for each of the primitives in the stack and determining a respective scaling factor for each of the primitives in parallel, wherein each scaling factor is operable to adjust a mass value of each of the primitives. Also, the method comprises scaling a mass value of each of the primitives in accordance with a respective scaling factor in parallel. Finally, the method comprises solving over a plurality of constraints iteratively using a scaled mass value for each of the primitives. | 2015-04-23 |
20150109290 | DEVICE AND METHOD FOR REMOVING NOISE POINTS IN POINT CLOUDS - In a noise points removing method, a point cloud of an object and predetermined parameters relating to the point cloud are received. The point cloud is triangulated to construct a triangular mesh surface, then, the point cloud is divided into a plurality of subsets according to the triangular mesh surface and the predetermined parameters. Each of the subsets of selected one by one, point distances between each point in the selected subsets and all points in adjacent subsets of the selected subsets and subset distances between the selected subset and each of the adjacent subsets according to the point distances are computed. Noise points can be determined according to a number of points in the each of the subsets, the predetermined parameters, and the subset distances, and then be removed. | 2015-04-23 |
