Abstract: The invention notably relates to a computer-implemented method for displaying a 3D assembly of modeled objects. The method comprises streaming from a first computer to a second computer at least one raster image of a first 3D modeled object, and rendering on the second computer the 3D assembly of modeled objects by merging a second 3D modeled object with the streamed at least one raster image.

Abstract: It is proposed a computer-implemented method for compressing a three-dimensional modeled object. The method comprises: providing a mesh of the three-dimensional modeled object; parameterizing (u,v) the mesh in a two-dimensional plane, the parameterization of the mesh resulting in a set of vertices having two-dimensional coordinates; providing a grid on the two-dimensional plane; and modifying the two-dimensional coordinates of each vertex by assigning one vertex to one intersection of the grid. Such compression method is lossless, completely reversible, suitable to efficiently reduce the storage size of a CAD file.

Abstract: The invention notably relates to a computer-implemented method for designing a 3D assembly of modeled objects. The method comprises rendering on a second computer a 3D assembly of modeled objects by merging a second 3D modeled object with at least one raster image of a first 3D modeled object, the at least one raster image having being streamed from a first computer to the second computer; sending from the second computer to the first computer first data related to the second 3D modeled object for contact computation between the first and second 3D modeled objects; and computing on the first computer a contact between the first and second 3D modeled objects.

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.
