Abstract: It is proposed a computer-implemented method for streaming a simulated three-dimensional modeled object from a server to a remote client, comprising the steps of: a) receiving on a server an interaction performed by a user on a remote client; b) performing on the server the steps of: simulating a three-dimensional modeled object based on the interaction; converting the result of the simulation into at least one two-dimensional image; compressing the said at least one two-dimensional image; and sending to the remote client the compressed at least one two-dimensional image.

Abstract: 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.
