Sample points of 3D curves sketched by a user

机译:用户绘制的3D曲线的采样点

摘要

The invention notably relates to a computer-implemented method for designing a three-dimensional modeled object comprising providing sample points of 3D curves sketched by a user; determining a volumetric function, within a predetermined class of volumetric functions, as the optimum of an optimization program that explores orientation vectors defined at the sample points under the constraint that the explored orientation vectors be normal to the 3D curves and respect a minimal rotation propagation condition over each 3D curve, wherein the optimization program penalizes a distance from the explored orientation vectors; and fitting the sample points with an isovalue surface of the volumetric function.
