20130116984 | Designing a Modeled Volume Represented by Dexels - It is provided a computer-implemented method for designing a modeled volume. The method comprises providing a set of dexels that represents the modeled volume, each dexel comprising a set of at least one segment representing the intersection between a line and the modeled volume, wherein the set of dexels is partitioned into groups of neighboring dexels, and wherein a memory space depending on the maximum number of segments comprised in each of the dexels of the group is allocated to each group; providing a sculpting operation on the modeled volume; and updating the set of dexels in response to the sculpting operation. Such a method improves the design of a modeled volume represented by a set of dexels. | 05-09-2013 |
20130116990 | Simulation Of The Machining Of A Workpiece - It is provided a computer-implemented method for simulating the machining of a workpiece with a cutting tool having a cutting part and a non-cutting part. The method comprises providing a modeled volume representing the workpiece and a trajectory of the cutting tool; determining a colliding sweep of the cutting tool, wherein the colliding sweep represents the volume swept by the non-cutting front of the cutting tool when the cutting tool follows the trajectory; testing a collision with the workpiece according to the determining step. Such a method improves the simulation of the machining of a workpiece with a cutting tool. | 05-09-2013 |
20130135302 | Creating a Surface from a Plurality of 3D Curves - It is provided a computer-implemented method for creating a surface from a plurality of 3D curves. The method comprises providing a plurality of 3D curves, determining crossings between pairs of the curves, defining a base graph comprising nodes representing the crossings and arcs connecting pairs of nodes representing crossings that are neighbors, determining, from the graph, a mesh comprising vertices defined by a 3D position and edges connecting pairs of the vertices, and fitting the mesh with a surface. Such a method makes the creation of a surface from a plurality of 3D curves easier. | 05-30-2013 |
